Answer:
A
Step-by-step explanation:
A
Distribute the x3 to each number. The coefficient stays the same but add exponent (3) onto each x. Final answer is: x to the seventh power plus 8X to the sixth power plus 2X to the fifth power +18 X to the fourth power +9x the third power
Answer:
- 
Step-by-step explanation:
=
( cross- multiply )
6x = 5y ( divide both sides by 6 )
x =
y
Then
← substitute x =
y into the expression
= 
= 
= 
=
× - 
= - 
Answer:
y= 3x-17
Step-by-step explanation:
When finding a parallel equation to y=mx+b, mx will always stay the same. So we have to find b.
In order to do this you plug the parallel lines passing point into the equation.
-5(y) goes into the y's spot. 4(x) goes into the x's spot.
-5 = 3 x 4 + b
-5 = 12 + b
-5 - 12 = 12 - 12 + b
-17 = b
y=3x-17
3.92 rounded to the nearest tenth should be 4.00 or 4, sorry if I’m wrong, have a good rest of your day/night
