Answer:
x = 6.125
Step-by-step explanation:
y = -2 + 34
so
-2x + 34 = 6x - 15
<u>+2x +2x </u>
34 = 8x - 15
<u>+15 +15</u>
49 = 8x
<em><u>x = 6.125</u></em>
plz mark as brianliest if correct!!!
To make x-y reasonable, you must make x the same value as y. It is the same as y-x. But a different variable order. For example x= 6 and y=9, and x - y is unreasonable, to make it reasonable, you must add 3 more to x to make it the way of y - x. So, your answer is just like 9-9 or 10-10 or any other subtraction equation with equal value, you don’t have to know what the variables equal, you just have to take an example and try it, that’s all you need to do to get out of the tricky problems. Hope this helps and have a great night of sleep :))
C, positive linear association. It is positive because it moves upward on the graph (left to right) and it is linear because it is a nearly straight line.
Answer:
-16 i sqrt(3) + 207
Step-by-step explanation:
Simplify the following:
(2 i sqrt(48) - 3) (-4 i sqrt(12) - 5)
sqrt(12) = sqrt(2^2×3) = 2 sqrt(3):
(2 i sqrt(48) - 3) (-4 i×2 sqrt(3) - 5)
-4×2 = -8:
(2 i sqrt(48) - 3) (-8 i sqrt(3) - 5)
Factor -1 from -8 i sqrt(3) - 5:
(2 i sqrt(48) - 3)×-(8 i sqrt(3) + 5)
sqrt(48) = sqrt(2^4×3) = 2^2 sqrt(3):
-(2 i×2^2 sqrt(3) - 3) (8 i sqrt(3) + 5)
2^2 = 4:
-(2 i×4 sqrt(3) - 3) (8 i sqrt(3) + 5)
2×4 = 8:
-(8 i sqrt(3) - 3) (8 i sqrt(3) + 5)
-(8 i sqrt(3) - 3) = -8 i sqrt(3) + 3:
-8 i sqrt(3) + 3 (8 i sqrt(3) + 5)
(-8 i sqrt(3) + 3) (8 i sqrt(3) + 5) = 3×5 + 3×8 i sqrt(3) + -8 i sqrt(3)×5 + -8 i sqrt(3)×8 i sqrt(3) = 15 + 24 i sqrt(3) - 40 i sqrt(3) + 192 = -16 i sqrt(3) + 207:
Answer: -16 i sqrt(3) + 207
