Find the midpoint of a segment whose endpoints are (9, –7) and (–3, 5).
suter [353]
For this question, you would have to use the midpoint formula. 
(X1 +X2 / 2 , Y1 + Y2 / 2)

In other words, 
(9 + -3 / 2 , -7 +5 / 2)
(6 / 2 , -2 / 2)
(3 , -1)

Your midpoint is (3, -1)

Alexeev081 [22]

For this case we have to:

Let "w" be the variable that represents the number of savings weeks.

We have that Landon's initial amount is $ 70.

y = 70 + 7w

After 5 weeks:

y = 70 + 7 (5)\\y = 70 + 35\\y = 105\

Answery = 70 + 7w\\y = 105

6x= 12
 divide both sides by 6
x=2
replace the x with 2

2= cucumber plants
10= tomato plants
