The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have
[tex]x_1=0,\ y_1=2.50\\\\x_2=1,\ y_2=5.00[/tex]
Substitute:
[tex]m=\dfrac{5-2.5}{1-0}=\dfrac{2.5}{1}=2.5[/tex]
y-intercept is for x = 0. Therefore y-intercept = 2.50.
The linear relationship: y = mx + b
m - slope
b - y-intercept
Substitute:
y = 2.5x + 2.5
Answer:Part A. the slope = 2.5 and y-intercept = 2.5Part B. y = 2.5x + 2.5Answer:
slope is 2.5
y intercept is 2.5
equation is y = 2.5x + 2.5
Step-by-step explanation:
We can find the slope by using the formula
m = (y2-y1)/(x2-x1)
= (27.5-2.5)/(10-0)
= (25/10)
= 2.5
The y intercept is the y value when x = 0
The y intercept is 2.5
The equation for the line can be written using the formula
y= mx +b where m is the slope and b is the y intercept
y = 2.5x + 2.5
Consider the diagram what is the length of segment ab
The length of segment AB is 9 units. So the answer is B) 9.
To find the length of segment AB, we can use the angle bisector theorem, which states that in a triangle, the length of the angle bisector from a vertex to the opposite side is proportional to the lengths of the two segments of that side.
Let's denote the length of AB as x.
Given that BC = 9 units and B is the midpoint of AC, AC = BC = 9 units.
Given that AD = 16 units.
Since B is the midpoint of AC, we can deduce that AB = BC = 9 units.
Therefore, the correct answer is B) 9.

The graph of f(x) = 2x + 1 is shown below. Explain how to find the average rate of change between x = 0 and x = 3.
Answer:
The rate of change is 7/3
Step-by-step explanation:
To find the average rate of change, we subtract the value of the function at the 2 points, over the difference of the 2 points.
f(3) -f(0)
-----------
3-0
f(3) = 2^(3)+1 = 8+1 =9
f(0) = 1 +1 = 1
9 -2
-----------
3-0
7/3
The rate of change is 7/3
Each line is one unit.
When X = 0, the blue line is at Y = 2
When x = 3, the blue line is at Y = 9
The average rate of change would be the change in y over the change in x.
The change in y = 9 - 2 = 7
The change in x = 3-0 = 3
The average rate of change would be 7/3

Hailey is starting a new exercise program. The first day she will spend 30 minutes on a treadmill. She will increase her time on the treadmill by 5 minutes each day for two weeks. Which function T(d), time in minutes, can be used to determine how many minutes Hailey will spend on the treadmill on any specific day.
Answer:
A) T(d) = 5d + 30
Step-by-step explanation:
Answer:
T(d) = 5d + 30
Step-by-step explanation:
Hailey is starting a new exercise program.
The first day she will spend 30 minutes on a treadmill.
She will increase her time on treadmill by 5 minutes each day for 2 weeks.
We have to form the function modeling this situation.
The equation will be in a linear form y = md + c
where c = constant term = 30 minutes
m = rate of change = Increase in time of exercise per day = 5
d = variable representing day
y = Second variable representing total time given for exercise
y = 5d + 30 or y = 5d + 30
We can rewrite the equation in the form of a function.
T(d) = 5d + 30
DEFG is a parallelogram. Segment DH = 2y + 6, segment HF = 4x + 1, segment HE = 3x + 2 and segment GH = 20. Find the value of x
Answer:
6
Step-by-step explanation:
If GH equals 20 so does HE so 3x6+2=20
Answer:
x=6
Step-by-step explanation:
given that DEFG is a parallelogram and the diagonals bisect at H.
Since diagonals bisect each other in a parallelogram, we have
DH = HF and EH = HG.
GH=20 is given. i.e. 3x+2 = 20
Subtract 2
3x = 18
Divide by 3
x =6
so answer is x =6.
We can find value of y also. DH =HF=4x+1
i.e. 2y+6 = 25
y = 9.5
Calculate the shaded area.
Give your answer to 3 significant figures and state it’s units.
To calculate the shaded area, determine the area of the entire shape and the area of the shaded region. Subtract the area of the shaded region from the area of the entire shape to find the shaded area.
Explanation:To calculate the shaded area, we first need to determine the area of the entire shape. Let's say the shape is a rectangle with a length of 10 units and a width of 6 units. The area of the rectangle is given by multiplying the length by the width, so in this case, the area is 10 units x 6 units = 60 square units.
Next, we need to determine the area of the shaded region. Let's say the shaded region is a right triangle with a base of 4 units and a height of 3 units. The area of a triangle is given by multiplying the base by the height and dividing by 2. So, the area of the shaded triangle is (4 units x 3 units) / 2 = 6 square units.
Finally, we can calculate the shaded area by subtracting the area of the shaded triangle from the area of the entire shape. The shaded area is 60 square units - 6 square units = 54 square units.

The bike shop is having a sale. Everything in the store is 20% off. A bike is originally priced at $345.00 What is the sale of the bike? Enter your answer in the box.
To find the sale price of a bike originally priced at $345.00 with a 20% discount, calculate the discount amount ($69.00) and subtract it from the original price, resulting in a sale price of $276.00.
Explanation:The bike shop is having a sale where everything in the store is 20% off. To calculate the sale price of a bike that is originally priced at $345.00, you first need to determine the discount amount. Convert 20% to a decimal by dividing 20 by 100, which gives you 0.20. You then multiply the original price of the bike, $345.00, by 0.20 to find the discount amount.
$345.00 \times 0.20 = $69.00
Next, subtract the discount from the original price to find the sale price.
$345.00 - $69.00 = $276.00
Therefore, the sale price of the bike is $276.00.
Meghan paid $7 dollars for a book. This price included a 20% discount. What was the original price of the book?
To find the original price of the book after a 20% discount, multiply the price paid by 0.2 and subtract the result from the price paid.
Explanation:To find the original price of the book, we need to determine the amount of the 20% discount and subtract it from the price Meghan paid. First, let's calculate the discount amount by multiplying $7 by 20% (or 0.2), which gives us $1.40.
Next, subtract the discount amount from the price Meghan paid: $7 - $1.40 = $5.60. The question asks us to find the original price of a book before a 20% discount which Meghan paid $7 for post-discount.
Therefore, the original price of the book was $5.60.

ABC is a straight line. the length of AB is four times the length of BC. AC = 75cm. work out the length of AB.
Answer:
AB = 60 cm
Step-by-step explanation:
AB + BC = AC
let the length of BC = x then AB = 4x, hence
4x + x = 75
5x = 75 ( divide both sides by 5 )
x = 15
AB = 4x = 4 × 15 = 60 cm
Given to us,
ABC is a straight line,
the length of AB is four times the length of BC,
AC = 75cm.
Equation 1As given to us, the length of AB is four times the length of BC. therefore, we can write it as, AB = 4(BC), which is equation 1 for us.
Equation 2Also, the length of the ABC will be constant. therefore, 75 cm. and the line AB and BC will together form the line ABC(AC). thus, we can write it as,
AB + BC = AC
Line BC
substituting the value of AB from equation 1 we get in equation 2,
4(BC) + BC = AC
5(BC) = AC
5(BC) = 75
[tex]\bold{(BC)=\dfrac{75}{5}}[/tex]
BC = 15 cm.
Line ABSubstituting the value of BC in equation 1, we get,
AB = 4(BC)
AB = 4 x 15
AB = 60 cm
Hence, the length of line AB is 60 cms.

Problem 1
Answer: Choice C) sample is appropriately large; margin of error is plus/minus 0.187
-----------------------------
Explanation:
At 90% confidence, the z critical value is roughly z = 1.645 (this is found using a table in the back of your textbook)
n = 250 is the sample size, which is appropriately large (it's over n = 30)
s = 1.8 is the standard deviation
The margin of error E is found by the formula below
E = z*s/sqrt(n)
E = 1.645*1.8/sqrt(250)
E = 0.18727008303518
E = 0.187
note: the sample mean is not used at all in the computation of the margin of error.

Problem 2
Answer: Choice D) both are effective; however, Intensity program is more effective compare to Q30X program
-----------------------------
Explanation:
There's not much to say here other than your teacher really wrote a lot to set up this problem. There's a lot of extra filler that you need to toss out and ignore. Basically the short of it is that Brant wants to run faster so he tests two programs. He finds that both are effective (since they both yield roughly the same percent decrease in run times) but the Intensity program is better by two percentage points. It's not much, but it's something. So this is why the answer is choice D.
===========================================
Problem 3
Answer: Choice A) appropriately large; margin of error is plus/minus 0.079
-----------------------------
Explanation:
n = 150 is the sample size. It is appropriately large as it is over n = 30
At 95% confidence, using a stats table (in the back of your book) you should find the critical value is z = 1.960
p = 0.56 is the decimal version of 56%, this is the proportion of those who use public transportation
We'll use a slightly different margin of error formula. This time it's to measure the error for proportions (rather than means)
E = z*sqrt(p*(1-p)/n)
E = 1.960*sqrt(0.56*(1-0.56)/150)
E = 0.07943845584267

Which two answers are correct ?
Answer:
Choice A) x and f(x) approach negative infinity
Choice D) x and f(x) approach positive infinity
Step-by-step explanation:
A cubic curve starts low and ends high if the leading coefficient is positive, which in this case it is. This means that the left side of the graph falls while the right side rises. Your teacher might say something like "fall to the left, rise to the right" to describe what the end behavior is doing.
More formally "fall to the left" means that as x approaches negative infinity, y = f(x) is approaching negative infinity as well. Similarly, "rise to the right" indicates that as x approaches infinity, y = f(x) heads off to infinity as well. Both x and y = f(x) move in the same direction along their respective number lines; eg, if one goes in the negative direction, then so does the other.

Florida has 8 less than 5 times the number of counties ,a, in Arizona. Georgia has 25 more than twice the number of counties, f, in Florida. Write an expression for the number of counties in Florida. Write an expression for the number of counties in Georgia.Arizona has 15 counties. How many do Florida and Georgia have? Number of counties Florida has: Number of counties Georgia has:
Answer:
Number of countries in Florida=5×a-8
Number of countries in Georgia=2×f+25
Step-by-step explanation:
Given that the number of countries in Florida is denoted by f, number of countries in Arizona is given by a and the number of countries in Georgia is given by g.
as Florida has 8 less than five times the number of countries in Arizona
So f=5×a-8
Georgia has 25 more than twice the number of countries in Florida
So g=2×f+25
Now it is given that Arizona has 15 countries i.e. a=15
So f=5×15-8
f=67
g=2×67+25
g=159
Hence, number of countries in Florida is:67
number of countries in Georgia is:159
Florida has 67 counties and Georgia has 159 counties, based on the expressions given and the number of counties stated for Arizona.
Explanation:The number of counties in Florida is represented by the expression 5a - 8, where 'a' is the number of counties in Arizona. Given that Arizona has 15 counties, we substitute 'a' with '15' in the expression to get 5*15 - 8 = 67. Hence, Florida has 67 counties.
The number of counties in Georgia is represented by the expression 2f + 25, where 'f' is the number of counties in Florida. Given that Florida has 67 counties, we substitute 'f' with '67' in the expression to get 2*67 + 25 = 159. Hence, Georgia has 159 counties.
