Answer:
try option D that should be correct
Step-by-step explanation:
To solve your X int you substitute 0 for y.
X int-
-5x+9(0)=-18
-5x=-18
X= 18/5 and the coordínate is (18/5,0)
Then to solve for y int you substitute 0 for x.
-5(0)+9y=-18
9y=-18
Y= -2 and the coordinate is (0,-2)
The answer is N=13(x+12), where x represents the amount of pounds Steven's boxes weighed and N represents the total number of pounds Nathan lifted.
Answer:
x = 81
Step-by-step explanation:
y = k√x
56 = k√49
56 = k(7)
Divide both sides by 7
8 = k
k = 8
------------------------
When y = 72
72 = 8√x
Divide both sides by 8
9 = √x
Square both sides
81 = x
x = 81
