The graph is shown below.
Step-by-step explanation:
Let x be the weight of fruit in pounds and P(x) be the price of fruit.
For fruit weighing greater than or equal to 0.01 pounds and less than or equal to 0.5 pounds, the amount charged is $2.00.
P(x) = $2.00 for 0.01 ≤ x ≤ 0.5
For fruit weighing greater than 0.5 pounds and less than or equal to 1.0 pounds, the amount charged is $3.50.
P(x) = $3.50 for 0.5 < x ≤ 1.0
For fruit weighing greater than 1.0 pounds and less than or equal to 1.5 pounds, the amount charged is $5.00.
P(x) = $5.00 for 1.0 < x ≤ 1.5
For fruit weighing greater than 1.5 pounds and less than or equal to 2.0 pounds, the amount charged is $6.50.
P(x) = $6.50 for 1.5 < x ≤ 2.0
For fruit weighing greater than 2.0 pounds and less than or equal to 2.5 pounds, the amount charged is $8.00.
P(x) = $8.00 for 2.0 < x ≤ 2.5

Write the equation of a line that is perpendicular to the given line and that passes through the given point.
y-3=-1/5(x+2);(-2,7)
The point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
m - slope
We have the line
[tex]y-3=-\dfrac{1}{5}(x+2)\to m=-\dfrac{1}{5}[/tex]
If m₁ and m₂ are the slopes of the perpendicular lines, then
[tex]m_1m_2=-1\to m_2=-\dfrac{1}{m_1}[/tex]
Therefore the slope of ouer line is
[tex]m=-\dfrac{1}{-\frac{1}{5}}=5[/tex]
We have the point (-2, 7). Put the coordinates to the equation of a line in the point-slope form:
[tex]y-7=5(x-(-2))[/tex]
[tex]y-7=5(x+2)[/tex] use the distributive property

show that the points p(7,12) and q(-3,-12) and r (14,5) lie on a circle with center c(2,0)
If the points P (7, 12), Q (-3, -12) and R (14, 5) lie on a circle with the center C (0, 2), then the distance OP, OQ and OR are the same.
The formula of a distance between two points:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Substitute:
[tex]OP=\sqrt{(2-7)^2+(0-12)^2}=\sqrt{(-5)^2+(-12)^2}=\sqrt{25+144}=\sqrt{169}\\\\\boxed{OP=13}\\\\OQ=\sqrt{(2-(-3))^2+(0-(-12))^2}=\sqrt{5^2+12^2}=\sqrt{25+144}=\sqrt{169}\\\\\boxed{OQ=13}\\\\OR=\sqrt{(2-14)^2+(0-5)^2}=\sqrt{(-12)^2+(-5)^2}=\sqrt{144+25}=\sqrt{169}\\\\\boxed{OR=13}[/tex]
OP = OQ = OR, therefore the points P, Q and R lie on one circle.

What is the equation of the line, in standard form, that passes through (4, -3) and is parallel to the line whose equation is 4x + y - 2 = 0?
answers:
4x - y = 13
4x + y = 13
4x + y = -13
Answer:
The equation of this line would be 4x + y = 13
Step-by-step explanation:
In order to find this equation we must first find the slope of the original line. To do this, we solve the original equation for y.
4x + y - 2 = 0
4x + y = 2
y = -4x + 2
The original slope (the coefficient of x) is -4, which means the new slope will also be -4 because parallel lines have the same slope. Now, we can use this slope along with the point in point-slope form to find the equation of the line. Just plug in the numbers and solve for the coefficient.
y - y1 = m(x - x1)
y + 3 = -4(x - 4)
y + 3 = -4x + 16
4x + y + 3 = 16
4x + y = 13
Find the x-intercepts (solve for x) for the following AND PLEASE SHOW YOUR WORK! y=−2x^2−9x+5
Answer:
see explanation
Step-by-step explanation:
To find the x- intercepts set y = 0, that is
- 2x² - 9x + 5 = 0
To factorise the quadratic consider the factors of the product of the coefficient of the x² term and the constant term that sum to give the coefficient of the x- term.
product = - 2 × 5 = - 10 and sum = - 9
The factors are - 10 and + 1
Use these factors to split the middle term
- 2x² - 10x + x + 5 = 0 ( factor the first/second and third/fourth terms )
- 2x(x + 5) + 1(x + 5) ( factor out (x + 5) )
(x + 5)(- 2x + 1) = 0
equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
- 2x + 1 = 0 ⇒ x = [tex]\frac{1}{2}[/tex]
x-intercepts are x = - 5 and x = [tex]\frac{1}{2}[/tex]

Answer: the two numbers is 35 and 18
Step-by-step explanation: 35+18=53 35-18=17
please mark brainliest
Final answer:
The two numbers are 35 and 18. We found these by solving the simultaneous equations x + y = 53 and x - y = 17, representing their sum and difference.
Explanation:
Finding Two Numbers Given Their Sum and Difference
Let's denote the two unknown numbers as x and y. According to the conditions given:
x + y = 53 (Equation 1: The sum of the two numbers)
x - y = 17 (Equation 2: The difference of the two numbers)
We can solve these two simultaneous equations to find the values of x and y.
Add the two equations:
(x + y) + (x - y) = 53 + 17
2x = 70
x = 35
Substitute x in Equation 1:
35 + y = 53
y = 53 - 35
y = 18
Therefore, the two numbers are 35 and 18.

a used automobile dealership recently reduced the price of a used compact car by 10 % if the price of the car before discount was $33500 find the discount and the new price
Answer: The new price is $3350.
Answer:
$3350; $30 150
Step-by-step explanation:
Original price = $33 500
Discount = 33 500 × 10 %
Discount = 33 500 × 0.10
Discount = $3350
New price = Original price - Discount
New price = 33 500 - 3350
New price = $30 150
Selling price is $70.00. Rate of the sales tax is 60%. That is the sales tax?
The sales tax would be $42.00, making the total cost $112.00.
To calculate the sales tax on an item, one must first convert the sales tax rate from a percentage to a decimal. Converting 60% to a decimal by dividing by 100 gives us 0.60.
Then, multiply this decimal by the selling price to find the amount of sales tax.
Amount of sales tax = price x rate of sales tax
So for a selling price of $70.00, the sales tax would be calculated as follows:
= $70.00 x 0.60 = $42.00
The sales tax on a $70.00 item at a rate of 60% is $42.00.
To find the total cost, one must add this tax to the original selling price.
Total cost = selling price + sales tax
Total cost = $70.00 + $42.00
Total cost = $112.00
Thus, the total amount paid including sales tax would be $112.00.

80 + 64 =144
Answer:
100 /( 5 x 4 + 4³) = 1 4/21
100 / 5 x 4 + 4³ = 144
Step-by-step explanation:
100 /( 5 x 4 + 4³)
PEMDAS tells us to do what is inside the parenthses
We will do the power in side the parentheses first 4^3 = 64
100 /( 5 x 4 + 64)
Now we will multiply
100/(20+64)
Now we add inside the parentheses
100/84
Divide the top and bottom by 4
25/21
Changing from an improper fraction to a mixed number
1 4/21
OR
100 / 5 x 4 + 4³
If the quantity is not in parentheses
We will do the power first 4^3 = 64
100 / 5 x 4 + 64
Then we do the multiplication and division from left to right
20 *4+64
80+64

To find whether it is a arithmetic or geometric sequence it is easiest to try to subtract term a2 from a1, seeing if d or r is positive. If that does not heed an answer try dividing a2 by a1 to see if it is a geometric sequence.
The terms go as follows just in case (They would normally be in subscripts)-
a1= -12
a2= -7
a3= -2
a4= 3
Answer: Yes; 5 (choice A)
We add 5 to each term to get the next
-12+5 = -7
-7+5 = -2
-2+5 = 3
and so on. The nth term formula is
an = -12 + 5(n-1)

five more then -8 times a number is 29. What is the number? Let the mystery number be represented by n.
Answer:
The mystery number is -3
Step-by-step explanation:
five more then -8 times a number is 29.
-8n +5 = 29
Subtract 5 from both sides
-8n +5-5 = 29-5
-8n = 24
Divide by -8 on each side
-8n/-8 = 24/-8
n= -3
The mystery number is -3
The mystery number in the equation is -3, determined by solving the algebraic equation 5 + (-8 × n) = 29.
The equation given in the problem statement translates to the mathematical expression 5 + (-8 × n) = 29, where n is the mystery number. To find the value of n, we can perform the following steps:
Subtract 5 from both sides to get -8n = 24.
Divide both sides by -8 to isolate n, giving us n = 24 / -8.
Calculate the result to find that n = -3.
Therefore, the mystery number is -3.

3,5 is increased by 2
5,8 is increased by 3. theres our pattern, each time it increases it follows the next number so the next 3 numbers it would be increased by is. 4,5,6.
Now knowing it is 4,5,6 we need to add, start adding.
8+4=12. Which answers have 12 in them? B and C.
We know 12 is the next number, now we add 5 to that.
12+5=17.
B has 17 but C doesn't, so that tells you its most likely going to be B. To make sure add 6 to 17.
17+6=23. Its true that it is B, as B is 12.17.23.
The next three terms in the sequence are 13, 21, and 34.
Explanation:The given sequence is 2, 3, 5, 8.
To find the next three terms in the sequence, we need to determine the pattern.
By observing the sequence, we can see that each term is obtained by adding the two previous terms.
For example,
3 = 2 + 1,
5 = 3 + 2, and
8 = 5 + 3.
Using this pattern, the next term would be obtained by adding 8 + 5, -
8 + 5 = 13
The two terms after that would be
13 + 8 = 21 and
21 + 13 = 34.
Therefore, the next three terms in the sequence are 13, 21, and 34.

If an image is being enlarged by 15% you would take the base number multiply it by the percent in decimal form and add the result to the base number.
4.25*0.15=0.6275
0.6375+4.25=4.8875
Answer: 4.8875
To find out the height of the photocopied drawing, we first calculate 15% of the original height (4.25 inches) and add this to the original height. The photocopied drawing is approximately 4.89 inches tall.
Explanation:The student photocopied a drawing with the copier set to enlarge the image by 15%. If the original drawing is 4.25 inches tall, the enlarged photocopied drawing would be larger by 15% of 4.25 inches.
Firstly, to find 15% of 4.25 inches, you multiply 4.25 by 0.15 (the decimal equivalent of 15%), which equals 0.6375 inches.
Adding this to the original height of the drawing, we get 4.25 inches + 0.6375 inches = 4.8875 inches, which is approximately 4.89 inches when rounded to two decimal places.
So, the photocopied drawing is approximately 4.89 inches tall.

Which grows faster as x increases, x3 or 3x? Explain.
As x increases, x^3 grows faster than 3x.
As x increases, the growth rate of x^3 (x cubed) is faster than that of 3x. This can be explained by comparing their respective derivatives.
The derivative of x^3 with respect to x is 3x^2, while the derivative of 3x is simply 3.
The derivative represents the rate of change, or the slope of the function at a given point. In the case of x^3, its derivative 3x^2 grows at a faster rate than the derivative of 3x, which is a constant (3).
This means that as x increases, the rate of change of x^3 (3x^2) increases faster compared to the rate of change of 3x (which is constant at 3). In other words, x^3 exhibits exponential growth, while 3x exhibits linear growth. So, as x increases, x^3 grows faster than 3x.
