Answer:
Explanation:
m = (y1 - y)/(x1 - x)
y1 = 50, y = 90
x1 = 2, x = 4
m = (50 - 90)/(2 - 4)
m = -40/-2
m = 20
b is the y intercept = 50
So our equation is written as:
y = 20x + 50
Answer:
120;60
Step-by-step explanation:
The measure of an angle is equal to twice the measure of its supplement.
This means that x = 2(180-x)
<em>Simplify</em>
x = 360 -2x
<em>Isolate the variable</em>
3x = 360
x = 120
This makes its supplement 60
4(.5*7*9)+(7*7)=175 sq cm
