Answer:
16 m²
Step-by-step explanation:
8 • 2 = 16
4(y-3) = 4*y -4*3
= 4y - 12
Hey!
------------------------------------------------
First, find the slope.
y2-y1/x2-x1
-20-(-5)/21-16
-15/5
-3
------------------------------------------------
Second, find the y-intercept.
We can solve for b with one of the points.
Put into slope-intercept form,
y = -3x + b
Substitute x and y with (16, -5)
-5 = -3(16) + b
-5 = -48 + b
-5 + 48 = -48 + b + 48
43 = b
------------------------------------------------
Third, put in slope-intercept form.
y = mx + b
m = slope
b = y-intercept
y = -3x + 43
------------------------------------------------
Hope This Helped! Good Luck!
Answer:
120
Step-by-step explanation:
3+9= 12
12+27= 39
