Answer:
a. 16
Step-by-step explanation:
Triangles = 180 degrees
180 - 80 = 100
100 = (4x - 4) + (0.5x + 32)
4x - 4 + 0.5x + 32 =100
(4x + 0.5x) +(-4 + 32) = 100
4.5x + 28 = 100
4.5x + 28 -28 = 100 - 28
4.5x = 72
4.5x/4.5 = 72/4.5
x = 16
Answer:
Quadratic equation follows form: ax^2 + bx + c = 0
a = 8
b = - 6
c = 13
The answer is y=-2x+6
We know the slope of the given equation is -2. A parallel line must have the same slope as the original function. So if we plug in the coordinates and the slope into the point slope formula we get y=-2x +6
Can you define it much more simpler
From the attached graph, we see that
f(x) is increassing in (- ∞ , -4), and
f(x) is decreasing in ( -4, ∞ )
therefore
The function is increasing for all real values of x where x < –4. TRUE
<span>The function is increasing for all real values of x where –6 < x < –2. (FALSE, f(x) is positive in this range)
</span><span>The function is decreasing for all real values of x where x < –6 and where x > –2. (FALSE, f(x) is negative in this range)
</span><span>The function is decreasing for all real values of x where x < –4. (FALSE, f(x) is decreasing ∀ x>-4</span>
