a) The Linear function will be:
b) After 50 months, the length will be 40 inches.
Step-by-step explanation:
In this question we need to find the linear function to model length L(t). We are given:
Length of hair to donate = 15 in
Growth of hair per month = 1/2 in
The Linear function will be:
- Now, determining the time t when her hair length reaches 40 inches.
Length of hair L(t) = 40
We need to find t in the above linear function
Subtracting 15 from both sides
Multiplying 2 on both sides
So, After 50 months, the length will be 40 inches.

It would be the second choice. Add by 25.
Answer:
2bricks
Step-by-step explanation:
volume of cuboid = length × breadth ×height
step 1 : calculate the first one
v= 15cm ×8cm× 5cm = 1200cm^3
step 2 calculate the 2nd one
v= 15cm ×10cm×8cm = 600cm^3
number of bricks
1200cm^3 × 1bricks/ 600cm^3 = 2 bricks
Answer:
(5, 0)
Step-by-step explanation:
Se the equations equal
x² - 2x - 15 = 8x - 40
Subtract 8x from both sides
x² - 10x - 15 = -40
add 40 to both sides
x² - 10x + 25 = 0
Factor
(x - 5)(x - 5) = 0
x = 5
---------------
plug in x = 5 into
y = 8x - 40
y = 8(5)- 40
y = 0
-----------------
Solution
(5, 0)
