Answer: The answer is B I'm pretty sure
We solve the equation: a = 50 + ( 90 - a );
Then, a = 140 - a;
2a = 140;
a = 140/2;
a = 70 (it is the measure of one angle);
90 - 70 = 20 (it is the measure of another angle);
Explanation:
The slope-intercept form of a line is:
y=mx+b
where:
m is the slope of the line
b is the y-intercept
We are given that m=4 and the line passes through (7,2).
∴2=4⋅7+b
2=28+b
b=−26
Therefore the equation of the line is:
y=4x−26
graph{y=4x-26 [-1.254, 11.23, -2.92, 3.323]}
40-4x=2/3x-10
50=14/3x
150/14=x
75/7=x
