balandron [24]

Answer:

6/5

Step-by-step explanation:

Using the given points (0, 3) and (-2.5, 0) you can substitute it into the slope formula which is y2-y1/x2-x1

In this case, 3 in the first parenthesis is the y2, while 0 in the second parenthesis set is 0.

so,

= substitute in the numbers for the slope formula: 3-0/0-(-2.5)

= reduce the fraction and you get: 1.2

= convert to simplified fraction to get: 6/5

Hope this helps, I did this on a quiz and got the answer right.

Consider the following formula used to estimate the height, h, of a seeding after w weeks since planting h=(1/5)w + (8/5)which o
Bogdan [553]

Answer:

w=5h-8

Step-by-step explanation:

Take the original formula h=(1/5)w+(8/5)

Subtract -8/5 on both sides to isolate the w, so h-8/5=(1/5)w

Now you have to get rid of the 1/5, so multiply 5(h-8/5), the 5 in the 8/5 cross each other out. You are left with 5h-8
