Answer: 0.25 + 0.5x = 2.5
Step-by-step explanation:
0.25 = the how long his hair is right now
0.5 = how much it grows each month
X= how many months it takes to reach 2.5 inches of hair
2.5= how long he'd like his hair to be
1) To graph y = 2x +3, give 2 different value for x & find its related y value:
for instance if x = 0 , then y = 3
if x = 1, then y = 5
Plot The coordinates of A(90,3) & B(1,5). You need just 2 point to draw a line.
2) The inverse of y=2x+3
a) Switch the x & y ===> x=2y+3
b) subtract 3 from both sides ===> x-3=2y+3-3===> x-3 = 2y
c) divide both sides by 2 ===> (x-3) / 2 =2y / 2 ==> 1/2(x-3)=y
And the inverse function of y = 2x+3 is y= 1/2(x+3)

Answer:
- 3/2
- it is the ratio of oil to vinegar in the dressing
- y = 3/2x
Step-by-step explanation:
1. The table can be filled in like this:
- (x, y)
- (0, 0)
- (2, 3)
- (4, 6)
- (6, 9)
The constant of proportionality is the ratio of y to x:
k = 3/2
__
2. The meaning of the constant of proportionality is just what it is defined to mean: the ratio of oil to vinegar in the dressing.
__
3. The equation is y=kx, where k is the value in part 1:
y = (3/2)x
