X=8 which is her age
8 is her cousin age
16 is Amy's age and the sum
Is 32
-7p=-2-6p
7p=2+6p
p=2
Hope this helps :)
Answer:
A. The height of the plant after week 3 was about 2.6 inches.
C. The height of the plant after week 9 was about 3.8 inches.
Step-by-step explanation:
The equation given:
Y = 0.2x + 2
x represents the number of weeks
substituting x = 3 into the equation , we will have
y = 0.2(3) + 2
y = 0.6 + 2
y = 2.6
This means that the height of the plant after week 3 was about 2.6 inches.
Also , substituting x = 9 into the equation will give
y = 0.2 (9) + 2
y = 1.8 + 2
y = 3.8
This means that the height of the plant after week 9 was about 3.8 inches.
Answer:
see explanation
Step-by-step explanation:
To find the y-intercept let x = 0, in the equation
6x - 3y = 15 → (1)
x = 0 : - 3y = 15 ⇒ y = - 5 ⇒ (0, - 5) ← y- intercept
x + 3y = - 8 → (2)
x = 0 : 3y = - 8 ⇒ y = -
⇒ (0, - ) ← y- intercept
