put the amount of $8 a pound chocolate as say it as x
As the total number of pounds is 20
so the amount of $3 a pound chocolate must be <span>20−x
so it will be</span>.
8x + 3(20 - x) = 5(20)
so correct option is C
hope it helps
Answer:
Step-by-step explanation:
From the graph in the attachment Y has coordinates:Y(3,2)
The transformation rule for a dilation with a scale factor k about the origin is:
In this case we have 
We substitute the coordinates and to get:
This simplifies to:
The first choice is correct.
The nearest percent increase in 53 to 68 is about 29 percent.
Answer:
y = 1/4x - 7/2
Step-by-step explanation:
To answer this question, we have to use point-slope form:
y - y1 = m(x - x1)
Substitute the numbers into the variables:
y - (-4) = 1/4(x - (-2))
y + 4 = 1/4(x + 2)
y + 4 = 1/4x + 1/2
y = 1/4x - 7/2
To verify your answer, simply substitute the values into your equation:
-4 = 1/4(-2) - 7/2
-4 = -1/2 - 7/2
-4 = -8/2
-4 = -4
