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
Answers
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
y-12.25=6.75(x-1)y=6.75x+5.5Related Questions

Answer:
220%
Step-by-step explanation:
The percentage change is computed by ...
% change = ((new value)/(old value) -1) × 100%
= (800/250 -1) × 100% = (3.2 -1) × 100%
= 220%
The increase was 220%.

What is the area of the polygon?
Answers
(The area of a quadrilateral is equal to length x width. So the area of the larger part of the polygon would be 32ft^2, the area of the small square is 4ft^2 and I’m assuming the area of the small triangle would be 2ft^2 because it has the same length and width as the small square but since it’s a triangle it’s area would be equal to half the area of the square. 32+4+2=38, so the answer would be 38ft^2.)

Find the equation of a line that is perpendicular to the line x=-9 and contains the point (-8,1)
Answers
Step-by-step explanation:
the line x = -9 had only one valid x value (-9), but then all values for y between -infinity and +infinity are valid.
does this sound familiar ?
it should, because the y-axis is the same type of line.
it is x = 0.
so, x = -9 is simply parallel to the y-axis.
and any line perpendicular to it (crosses the original line in a right angle = 90 degrees) is then parallel to the x-axis.
there the situation is upside-down: there is only one valid y value, and all values between -infinity and +infinity are valid x values.
since the specified point on that line has y = 1, it means that the whole line is
y = 1

Answer:
parallel: y = -7x -44perpendicular: y = 1/7x -8/7Step-by-step explanation:
The given equation is in slope-intercept form:
y = mx +b . . . . . . line with slope m and y-intercept b
For the purpose of this question, you need to recognize that the line with equation ...
y = -7x +8
has a slope (x-coefficient) of -7.
The parallel line will have the same slope (x-coefficient).
The perpendicular line will have a slope that is the opposite reciprocal of this:
m = -1/(-7) = 1/7
Each line will have a y-intercept (b) that makes the line go through the given point. The y-intercept can be found by solving the slope-intercept equation for b:
b = y - mx . . . . . . where (x, y) is the point you want the line to go through
__
parallel line:
b = -2 -(-7)(-6) = -2 -42 = -44
The equation of the parallel line is y = -7x -44.
__
perpendicular line:
b = -2 -(1/7)(-6) = -14/7 +6/7 = -8/7
The equation of the perpendicular line is y = 1/7x -8/7.

where a, b and care positive integers.
Work out the values of a, b and c.
Answers
Answer:
[tex]a=9, b=26, c=24[/tex]
Step-by-step explanation:
Let's expand the expression bit by bit.
[tex](x+2)(x+3)=(x)(x)+(x)(3)+(2)(x)+(2)(3)=x^2+5x+6[/tex] by FOIL.
We have that [tex](x^2+5x+6)(x+4)=x(x^2+5x+6)+4(x^2+5x+6)=x^3+5x^2+6x+4x^2+20x+24=x^3+9x^2+26x+24[/tex].
So, the answer is [tex]\boxed{a=9, b=26, c=24}[/tex]
A cubic polynomial is a type of polynomial with the degree of 3 i.e. the highest exponent of the variable is 3.
The general form of a cubic polynomial is written as p(x): ax³ + bx² + cx + d, a ≠ 0, where a, b, and c are coefficients and d is the constant with all of them being real numbers.
Given:
(x + 2)(x + 3)(x + 4)
Now, Multiplying the monomial
= (x² + 2x + 3x+ 6 ) ( x+4)
= (x² + 5x+ 6 ) ( x+4)
= x³ + 4x² + 5x² + 20x + 6x+ 24
= x³ + 9x² + 26x+ 24
Now, Comparing it with the standard form of cubic Polynomial
ax³ + bx² + cx + d
So, a= 1, b= 9, c= 26 and d= 24.
