Answer:

Step-by-step explanation:

(x + 43) +29 + (180 - 111) = 180 ----- (x+43 = 1st angle; 29 = 2nd angle (vertical angle theorem); 180 -111 = 3rd Angle (Linear Pair); 180 = Sum (Tirnagle Angle Sum))

x + 43 + 29 + 69 = 180 -->

x + 141 = 180 -->

x = 39

A linear function has a slope of Negative StartFraction 7 Over 9 EndFraction and a y-intercept of 3. How does this function comp

Svet_ta [14]

Answer:

They are the same line written in different forms.

Step-by-step explanation:

Given a linear function with a slope of $-\frac{7}{9}$ and a y-intercept of 3.

The equation of the line in the slope-intercept form is given as:

$y=-\frac{7}{9}x+3$

Given the other line,

$y+11=-\frac{7}{9}(x-18)$

Simplified:

$y+11=-\frac{7}{9}x+14\\y=-\frac{7}{9}x+14-11\\y=-\frac{7}{9}x+3$

The two lines are one and the same line.
