Answer:
Step-by-step explanation:
olve the line equation for y
:
y = -ax/2 +5
:
therefore, the y-axis intercept is 5
:
area of triangle = (1/2) * base * height
:
(1/2) * base * 5 = 10
:
base = 4 which is the x-axis intercept
:
-a(4)/2 +5 = 0
:
-2a = -5
:
a = 5/2
:
Basically multiply the 2 inside the bracket, then addition and subtraction. For the -2x=-52 part. Move -2 to divide the -52, you'll get x = -52/-2 as you'll get x = 26 because minus * minus or minus divide minus will always be positive.
