70+80+(m+10)= 180°
150+m+10=180
160+m=180
m=20°
Answer:
Step-by-step explanation:
Simplifying
8x + 5y = 27.15
Solving
8x + 5y = 27.15
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5y' to each side of the equation.
8x + 5y + -5y = 27.15 + -5y
Combine like terms: 5y + -5y = 0
8x + 0 = 27.15 + -5y
8x = 27.15 + -5y
Divide each side by '8'.
x = 3.39375 + -0.625y
Simplifying
x = 3.39375 + -0.625y
Answer:

Step-by-step explanation:
<h3><u>Given functions:</u></h3>
- f(x) = 4x² - 6
- g(x) = x² - 4x - 8
<h3><u>Solution:</u></h3>
Subtract both functions
(f-g)(x) = 4x² - 6 - (x² - 4x - 8)
(f-g)(x) = 4x² - 6 - x² + 4x - 8
Combine like terms
(f-g)(x) = 4x² - x² + 4x - 6 - 8
(f-g)(x) = 3x² + 4x - 14
