Answer:
Step-by-step explanation:
Corresponding angles are congruent
x² - 72 = 6x
x² - 6x - 72 = 0
Sum = -6
Product = -72
Factor = -12 , 6 {-12*6 = -72 & -12 +6 = -6}
x² + 6x - 12x -72 = 0
x(x + 6) - 12(x + 6) = 0
(x + 6)(x -12)=0 {Ignore x + 6 = 0 because angles won't be in negative}
x - 12 = 0
x = 12
Answer: is brainly broken for u too??
Step-by-step explanation:
57 + x + x + 130 = 167
57 + 2x + 130 = 167
187 + 2x = 167
- 187 - 187
---------------------------
2x = -20

x = -10
5 because they would most likely want a high amount of coins it's common sense. But if they were very strategic they'd probably also pick 3 but most of the time the value expected would be 5.
Answer:
<h2>
y = (-2/3)x - 4</h2>
Step-by-step explanation:
As we move to the right from (-3,-2) to (6,-8), x increases by 9 and y decreases by 6. Thus, the slope of the line connecting these two points is
m = rise / run = -6 / 9 = -2/3.
Starting with the slope-intercept form of the equation of a straight line,
y = mx + b, and substituting -2/3 for m, -8 for y and 6 for x, we get the following equation, which enables us to solve for the y-intercept, b:
-8 = (-2/3)(6) + b, or
-8 = -4 + b
Then b = -4, and the desired equation is
y = (-2/3)x - 4.
