Answer:
Step-by-step explanation:
I guess the angles are supplementary, which means they have a sum of 180º.
11x - 15 + 5x - 13 = 180
16x -28 = 180
16x = 208
x = 13
Answer:
f(-6) = 3
Step-by-step explanation:
In order to find the value of f(-6), we need to find what y-value appears associated with x = -6 according to the graph resented.
Therefore, go to x = -6 on the horizontal axis (six units to the left of the origin of the coordinate system), and find at what value of the y-axis the vertical grid passing through x = -6 intercepts the graph of the function.
That is indicated by a red dot in the attached image.
We see therefore that for x = -6 the y-value that the graph of the function shows in the vertical scale is "3".
Then, f(-6) = 3
Answer:
x = 16
Step-by-step explanation:
Verticle angles are always congruent, so:
(8x + 15) = 143
Now, we can solve to isolate x:
8x + 15 - 15 = 143 - 15 (subtract 15 from both sides)
8x/8 = 128/8 (divide both sides by 8)
x = 16
You can always plug in the value of x to the original equation to check your answer:
8(16) + 15 = 143
