What is the positive difference in the y-intercept value of f(x) and g(x) ?
Enter your answer in the box.
Final answer:
The y-intercept of function f(x) can be found by using the given points to determine the slope and then plugging in the slope and a point into the point-slope equation. The y-intercept of function g(x) is given by the table. The positive difference in the y-intercept values of f(x) and g(x) is -0.5.
Explanation:
The y-intercept of a linear function represents the value of the function when x is equal to 0. To find the y-intercept of function f(x), we can use the given points (0,1) and (2,7) to determine the slope of the line. The slope is calculated by taking the difference in the y-coordinates and dividing it by the difference in the x-coordinates:
slope = (7 - 1) / (2 - 0) = 3.
Now that we have the slope, we can use the point-slope form of a linear equation to find the equation of the line:
y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.
Using the point (0,1) and the slope 3, we get:
y - 1 = 3(x - 0).
Simplifying the equation gives us:
y = 3x + 1.
The y-intercept of function g(x) is given by the table as the value of g(x) when x = -1, which is 1.5.
The positive difference in the y-intercept values of f(x) and g(x) is given by:
1 - 1.5 = -0.5.

Two angles form a linear pair. The measure of one angle is 2/3 the measure of the other angle. Find the measure of each angle
Answer:
108° and 72°
Step-by-step explanation:
let one angle be x then the other angle is [tex]\frac{2}{3}[/tex] x
the sum of the 2 angles = 180°, hence
x + [tex]\frac{2}{3}[/tex] x = 180 ( combining the left side )
[tex]\frac{5}{3}[/tex] x = 180
multiply both sides by 3 then divide both sides by 5
5x = 540 ⇒ x = 108
the 2 angles are x = 108° and [tex]\frac{2}{3}[/tex] x = 72°

What is the value of the underlined digit? 526
In the number 526, the underlined digit '5' represents the 100's place, so its value is not simply 5, but 500. A helpful tool to work with such problems is the place value chart.
Explanation:In the number 526, the emphasized or underlined digit represents the 100's place. So, the value of this specific digit, which happens to be 5, isn't simply 5 but 500 in the context of this particular group of digits. You can easily understand this by breaking down the number: 526 equals 500 (5 hundreds) plus 20 (2 tens) plus 6 (6 ones).
Another easy method to identify the value of an underlined or specific digit in a number is by knowing the place value chart, which runs from right to left as: Ones, Tens, Hundreds, Thousands, and so on. The third digit from right is the Hundreds place, and since in 526, 5 is in this position, its value becomes 500.

When Stephanie was 13 years old she had 137 baseball cards. Each year for her birthday she got 25 more. Stephanie is now 28 years old. Assuming Stephanie has not lost or destroyed any cards, how many baseball cards does she have now?
Answer:
512 baseball cards
Step-by-step explanation:
At 13, Stephanie had 137 baseball cards.
There are 28-13 = 15 years between 13 and 28
For those 15 years, she got 25 cards a year.
15 * 25 = 375
In those 15 years, she got 375 cards.
She started with 137, and she gained 375.
137+375 = 512
She now has 512 cards.

the area of a rectangular dog pen is 8 1/2 square feet. if the width is 3 2/5 feet, what is the length, in feet?
Answer:
Area of rectangle is equal to multiply the length by width
i.e [tex]A = l\times w[/tex] .....[1]
where
A is the area of rectangle ,
l is the length and
w is the width of the rectangle respectively.
Given : Area of rectangular do pen(A) = [tex]8\frac{1}{2} = \frac{17}{2}[/tex] square feet and width(w) = [tex]3\frac{2}{5} = \frac{17}{5}[/tex] feet.
To calculate the length in feet.
Substitute the given values in [1], we get
[tex]\frac{17}{2}= l\times \frac{17}{5}[/tex]
Multiply both sides by [tex]\frac{5}{17}[/tex] we get;
[tex]l = \frac{17}{2} \times \frac{5}{17} =\frac{5}{2} = 2\frac{1}{2}[/tex] feet.
Therefore, the length in feet is, [tex]2\frac{1}{2}[/tex]
there are 75 students in a speech contest. Yesterday, 1/3 of them gave their speeches. Today, 2/5 of the remaining students gave their speeches. how many students still haven't given their speeches?
Answer:
30 students
Step-by-step explanation:
Yesterday: 1/3 of the 75 students (75 / 3) = 25 students
There are now 50 students remaining to give their speeches.
Today: 2/5 of the 50 students (50 / 5 = 10 x 2 ) = 20 students
50 - 20 = 30 students remaining to give their speeches.
Therefore, 30 students still haven't given their speeches.
To find out how many students still haven't given their speeches, we first need to calculate the number of students who gave their speeches yesterday and today. Since there were 75 students in total and 1/3 of them gave their speeches yesterday, we multiply 75 by 1/3:
75 * 1/3 = 25 students
This means that 25 students gave their speeches yesterday. To find out how many students were left for today, we subtract the number of students who gave speeches yesterday from the total number:
75 - 25 = 50 students remained
Today, 2/5 of the remaining students gave their speeches. We calculate this by multiplying the number of remaining students by 2/5:
50 * 2/5 = 20 students
Therefore, 20 students gave their speeches today. Now, we subtract the number of students who have given their speeches today from the remaining number of students to find out how many have not given their speeches yet:
50 - 20 = 30 students
Thus, 30 students still haven't given their speeches.

Answers:
Problem 1) ASA
Problem 2) ASA
Problem 3) AAS
Problem 4) Neither
Problem 5) AAS
Problem 6) Neither
==============================
Explanation:
Any time we have ASA is when we can match up two pairs of angles and a pair of sides between the two pairs of angles. With problems 1 and 2, this happens. The corresponding angles that are congruent are the ones that have the same angle markers.
AAS is slightly different from ASA in that the side is not between the angles. This happens with problem 3 and problem 5. For problem 3, for instance, the second pair of angles are the two vertical angles. These angles are not marked, but they are congruent due to the vertical angle theorem. The same thing can be said about problem 5 as well.
With problem 4 and problem 6, we don't have any information about any pairs of angles, so we can't use AAS or ASA at all. We don't know if the triangles are congruent or not. They might be, but we simply don't have enough info to say either way.

Why is partitioning a directed line segment into a ratio of 1:3 not the same as finding the length of the directed line segment?
The ratio given is part to whole, but fractions compare part to part.
The ratio given is part to part. The total number of parts in the whole is 3 – 1 = 2.
The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4.
The ratio given is part to whole, but the associated fraction is .
Answer:
The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4.
Step-by-step explanation:
We know that partitioning a directed line segment into a ratio of 1:3 means that we are dividing the given line segment into two parts whose first part is 1 times the of some quantity while the another part is 3 times of the same quantity. So basically we are comparing part to part in by ratio. And total number of parts in the whole will be just sum of both so we get 1+3=4
Hence choice (3) is correct answer.
"The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4."
Final answer:
Partitioning a directed line segment into a ratio of 1:3 is not the same as finding the length of the directed line segment. The ratio compares parts within the whole, while finding the length involves measuring the entire segment. To find the length of each part in a 1:3 ratio, divide the length of the segment by 4.
Explanation:
Partitioning a directed line segment into a ratio of 1:3 is not the same as finding the length of the directed line segment because the ratio given is part to whole, while finding the length involves determining the actual measurement of the segment. The ratio 1:3 compares the parts within the whole, while finding the length of the segment involves measuring the entire length.
When the ratio is given as 1:3, it means that the segment is divided into 4 equal parts (1 part + 3 parts). The length of the entire segment is the sum of these 4 parts. To find the length of each part, you can divide the length of the segment by 4.
For example, if the length of the segment is 8 units, each part will have a length of 8/4 = 2 units.

what is the slope of a line perpendicular to the line of y=-1/4x-1
Answer: 4
The given line has a slope of -1/4 as this is the number in front of the x. The general equation y = mx+b has m as the slope. So m = -1/4 is given
Flip the sign to get -1/4 turn into +1/4 or just 1/4
Then flip the fraction (aka reciprocal) to go from 1/4 to 4/1 and that simplifies to 4.
Multiplying the original slope (-1/4) and the perpendicular slope (4) will result in -1.

Answer:
the correct option is D: 1.33 just finished test need any other answers feel free to message me :)
Answer:
1.33 cm/sStep-by-step explanation:
The line is going from point (0;0) to point (12;16), the proportional relationship between these points refer to the slope of the line, which can be found with this expression:
[tex]m=\frac{\Delta y}{\Delta x}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Replacing all values we have:
[tex]m=\frac{16-0}{12-0}=\frac{16}{12}=1.33[/tex]
Therefore the relation shown in the graph is represented by 1.33 cm/s, which refers to the constant speed developed by the object.
