Answer:
a) find the value of y when x is equal to 4.
Step-by-step explanation:
Edward sliced 6 chocolate cakes and 12 lemon cakes
Answer:
2. y = 7/2 x -2
3. y = 3/4x-1
Step-by-step explanation:
points (0,-2) (4,12)
slope = (y2-y1)/(x2-x1)
slope = (12--2)/(4-0)
= (12+2)/4
= 14/4 = 7/2
the slope is 7/2 and the y intercept is -2
y = mx+b
y = 7/2 x -2
points (0,-1) (4,2)
slope = (y2-y1)/(x2-x1)
slope = (2--1)/(4-0)
= (2+1)/4
= 3/4
the slope is 3/4 and the y intercept is -1
y = mx+b
y = 3/4x-1
Function 1 can be described by
c = 35 +10p
Function 2 can be described by
c = 35 +15p
The functions have the same initial value. <=== ANSWER
_____
The functions are not the same. The rate of change for Tour 2 is greater.
-8k - 8(-8k + 6) = -8k + 64k - 48 = 56k - 48
