Answer:
x = 59°
y = 67°
Step-by-step explanation:
x = y - 8
x + y + 54 = 180
(y - 8) + y = 180 - 54
2y - 8 = 126
2y = 134
y = 67°
x = 59°
Step-by-step explanation:
10(0.5x + 6) = 8
5x + 60 = 8
5x = 8 - 60
5x = -52
x = -52/5
x = -10.4
Answer:
$569.50
Step-by-step explanation:
15% deduction from the initial price(100%) will have us remaining with 85%
100% = 670
85% = <u>85% x 670</u>
100%
= $569.50
Answer:
C
Step-by-step explanation:
Starting with the first part, shifting 2 units left, this means that for this new function, for each value of x, the original function is equal to if you plugged in a value 2 values higher. Therefore, we should be looking for a x+2 -- that's C. Then, for the second part, we need to go up 9 units, which adds 9, so C fits that as well.
The answer to your question is (C)
1 by itself added to 2/5 would go on the side and look like: 1 2/5
So (C)
