Answer:
x = -6 and x = 1
Step-by-step explanation:
It's a little easier to see what must be done here if you write this problem as:
3
(1/2)x = -------------
x + 5
Multiply both sides by 2 to eliminate the fraction 1/2:
6
x = ---------------------
x + 5
Now cross multiply: we get x(x + 5) = 6, or:
x^2 + 5x - 6 = 0, or
(x + 6)(x - 1) = 0, so that x = -6 and x = 1. Both are valid answers, as the given expression is true if you substitute these x-values one at a time
Answer:
Step-by-step explanation:
Given expression is,
f(x) = 8x³ - 6x² - 36x + 27
For zeros of the function,
f(x) = 0
8x³ - 6x² - 36x + 27 = 0
2x²(4x - 3) - 9(4x - 3) = 0
(2x² - 9)(4x - 3) = 0
(2x² - 9) = 0
x² =
x =
x =
Or (4x - 3) = 0
x =
Therefore, all zeros of the given functions are .

Answer:
- 128°
- 52°
- 47°
- 133°
- 81°
Step-by-step explanation:
Alternate interior angles are congruent, so you know ...
∠2 = 52°
∠3 = 47°
The sum of angles in a triangle is 180°, so ...
∠5 = 180° -∠2 -∠3 = 180° -52° -47°
∠5 = 81°
Linear pairs are supplementary, so ...
∠1 = 180° -∠2 = 180° -52°
∠1 = 128°
∠4 = 180° -∠3 = 180° -47°
∠4 = 133°
_____
<em>Alternate solution</em>
To find angles 1 and 4, you could also make use of the fact that same-side interior angles are supplementary.
