To find the y int, sub in 0 for x and solve for y
0 + 2y = 72
2y = 72
y = 72/2
y = 36....so ur y int is (0,36)
to find the x intercept, sub in 0 for y and solve for x
x + 2(0) = 72
x = 72....and ur x int is (72,0)
Plug each x-value into the equation to get the y-value:
(2,-1)
(0,-2)
The answer to your question is precisely 99
I'm not sure that I am 100% right but I'll give it a shot.
50+75= 125*0.35=43.75
$43.75
To find the answer, we can first find the age of Rolando in four year:
17+4
=21
We can then proceed to find the current age of Marisa,which is 3/2 of Rolando’s age calculated above:
Let Marisa’s age be y.
3/2 y =21
y = 21 × 2/3
y = 42/3
y = 14
Therefore Marisa is currently 14 years old.
In three years, Marisa would be:
14+3
=17
Therefore, she will be 17 years old.
Hope it helps!
