Step-by-step explanation:
2x + 1 + x - 13 = 180° because these angles are supplementary
3x - 12 = 180°
3x = 180 + 12
3x = 192 divide both sides by 3
x = 64
2x + 1 ➡ 2 × 64 + 1 = 129°
x - 13 ➡ 64 - 13 = 51°
Answer:
Slope = 
Step-by-step explanation:
The equation for finding slope is:
In the equation, m is the slope, x is the x-intercept, and b is the y-intercept. The number next to x is ALWAYS the slope.
Your equation:
The number(fraction) next to x is . Therefore, your answer will be

Answer: 7/16 of a yard
Step-by-step explanation:
first we have to find common denominators. 3x=7/8, or 3x=14/16
1/4=4/16 then 14-4-3=7, all over 16.
17.) (-2,0) & (5,0)
19.)(-8,0) & (-7,0)
20.)(-5,0) &(1.5,0)
21.)(-2,0) &(8,0)
I put all of them into Desmos the x’s or solutions are when the u shaped graphs pass through the x-axis
