8. Jackie is creating a spreadsheet to keep a record of amounts she has collected
from customers for candy boxes she has sold to them. She must write a linear
equation in two variables to represent the amount collected in terms of
number of boxes sold. She has been using the table below to determine the
amount to charge.
Which linear equation in two variables can Jackie used to represent the amount of collected in terms of number boxes sold in her spread sheet?
A. y=5.5x+6.75
B.y=13.5x-1.25
C.y=13.5x+12.25
D.y=6.75x+5.5
Answer:
D. y = 6.75x + 5.5Step-by-step explanation:
The slope intercept form:
y = mx + b, where m- slope, b- y-interceptUse two ordered pairs from the table and work out the equation.
(1, 12.25) and (3, 25.75)Find the slope:
m = (y₂ - y₁)/(x₂ - x₁)m = (25.75 - 12.25)/(3 - 1) = 13.5/2 = 6.75Find the y- intercept:
12.25 = 6.75*1 + bb = 12,25 - 6.75b = 5.5The equation is:
y = 6.75x + 5.5Correct choice is D
Slope
m=(25.75-12.25)/3-1m=6.75Equation in point slope form

Answer:
D) 22
Step-by-step explanation:
B is the midpoint. The midpoint is the point in a line that breaks the line into two equal segments. With that info, we know that BC = AC.
So that means:
3x - 14 = x + 10
Now solve this equation.
3x - 14 = x + 10
+14. +14
3x = x + 24
-x
2x = 24
/2. /2
X = 12.
Now we know the value of x, insert the value into x + 10.
12 + 10 = 22
The answer is 22
Answer:
B) 12
Step-by-step explanation:
Because,
3x - 14 = x + 10
3x - x = 10 + 14
2x = 24
x = 12

A 3m wide road runs around a circular park whose circumference is 132m . Find the cost of fencing the outer boundary of the road at the rate of $10 per m
Answer:
$ 1508.57 and please give brainliest
Step-by-step explanation:
The road around the park = 3 m wide,
and the circumference of the park = 132 m,
We have to find the cost of fencing
the outer boundary,
the rate = $10 per m
Step-by-step explanation:
As we know that the circumference
of a circle = 2 × 22÷7 × radius
2 × 22÷7 × radius = 132 m,
44 × radius = 132 m × 7,
44 × radius = 924 m,
radius = 924 ÷ 44 m
So, radius = 21 m ( smaller circle )
radius = 21 m + 3 m ( larger circle )
= 24 m
Usually, we fence on the borders means it's
the circumference of the larger circle
= 2 × 22÷7 × radius
= 44÷7 × 24 m
= 1056÷7 m
= 150.85 m
cost of fencing = $ 10/m
total cost = 150.85 × $ 10
= $ 1508.57

Write an equation for a parabola with x-intercepts (-4,0) and (2,0) which passes through the point (1,-10).
Answer:
y=2x^2+4x−16
Step-by-step explanation:
Assume that the equation of the parabola is y=ax2+bx+c.
Since the parabola passes through the point (−4,0), then 0=16a−4b+c.
Since the parabola passes through the point (2,0), then 0=4a+2b+c.
Since the parabola passes through the point (1,−10), then −10=a+b+c. Thus, we have obtained the following system:
{16a−4b+c=0; 4a+2b+c=0; a+b+c=−10Solving it, we get that a=2, b=4, c=−16. Thus, the equation of the parabola is y=2x^2+4x−16.
The equation of a parabola is y = -x² + x + 4 with x-intercepts at (-4,0) and (2,0) that passes through the point (1,-10).
What is the equation for a parabola?A parabola can be represented by the equation:
y = ax² + bx + c
To find the equation of a parabola that has x-intercepts at (-4,0) and (2,0), we can set y equal to 0 and solve for x to find the x-intercepts:
0 = a(-4)² + b(-4) + c
0 = a(2)² + b(2) + c
Solving these equations for a and c gives us:
c = b(-4)
c = -2b
The parabola passes through the point (1,-10), we can substitute the values of x and y into the equation to solve for b:
-10 = a(1)² + b(1) + (-2b)
-10 = a + b - 2b
-10 = a - b
Substituting c = b(-4) into the equation gives us:
y = a x² + b x + b(-4)
Substituting a = -b and solving for b gives us:
y = (-b) x² + b x + b(-4)
y = -b(x² - x - 4)
Since the x-intercepts are at (-4,0) and (2,0), the coefficient of x², which is -b, must be positive. Therefore, we can set b = 1 to get the equation of the parabola:
y = -(1)(x² - x - 4)
y = -x² + x + 4
Thus, the equation of a parabola is y = -x² + x + 4.

Answer:
A) 23+x = 35
x = 12
Step-by-step explanation:
The question is asking you to find the equation and variable that best represents the scenario. We know that Emily had 35 dollars and had 7 dollars after paying for everything. This means that 7 plus what she spent must equal 35. However, we only know the cost of the ticket. So, add the cost of the ticket to the money left to figure out part of the equation. This equals 23 dollars. Therefore, whatever is left must be what she spent on lunch. So, the equation should look like 23 + x = 35. This is because the $23 is the ticket/the amount left and the x is the cost of lunch. Together they equal what Emily brought to the fair.

Answer:
19, 18, 15.5
Step-by-step explanation:
To solve this problem, you need to substitute the given values into the function.
b(x = -2) = 18 - 0.5(-2) = 18 + 1 = 19
b(x = 0) = 18 - 0.5(0) = 18 - 0 = 18
b(x = 5 ) = 18 - 0.5(5) = 18 - 2.5 = 15.5

the sum of three numbers is 20
the first is 4 times the sum of the other two
the second is seven times the third
what is the product of all three
Answer:
A*B*C= 28
Step-by-step explanation:
A+B+C=20
1. A = 4(B+C)
2. B = 7C
3. C = C
----------------------
1.
A = 4( 7C + C )
A=4(8C)
A= 32C
---------------------
A+B+C=20
32C + 7C + C = 20
40C = 20
C = 20/40
C = 1/2
------------------------
A= 32(1/2) = 32/2 = 16
B= 7(1/2) = 7/2
C= 1/2
A*B*C = 16 * 7/2 * 1/2
A*B*C= 28

Answer:
7 words per minute
Step-by-step explanation:
1. To find the unit rate (words per minutes), let's set up two ratios:
63:9 = x:1 or 63/9 = x/12. Now, let's solve for x to find how many words she can type per minute.
Step 1: Cross-multiply.
[tex]9 * x = 63 * 1[/tex] [tex]9x = 63[/tex]Step 2: Divide both sides by 9.
[tex]\frac{9x}{9} = \frac{63}{9}[/tex] [tex]x = 7[/tex]Therefore, Christine can type 7 words per minute.
