What is the value of x? −7.5(x−3)=3.75

Elena L [17]

${\boxed{ \Huge{ \blue{ \mathcal{{ Answer}}}}}}$

⇛-7.5(x−3) = 3.75

⇛-7.5x + 22.5 = 3.75

⇛-7.5x = 3.75 - 22.5

⇛-7.5x = -18.75

⇛x = -18.75 ÷ -7.5

⇛x = -18.75/-7.5

⇛x = 2.5

Complete the solution of the equation. find the value of y when x equals -8 8x+8y=-48

Korvikt [17]

8x + 8y = -48
-------------------------
Plug in -8 for x
(8) (-8) + 8y = -48
-------------------------------
Simplify
(8) (−8) + 8y = −48
−64 + 8y = −48
8y − 64 = −48
-----------------------------------------
Add 64 to each side
8y − 64 + 64 = −48 + 64
8y = 16
---------------------------------------------------
Finally, divide each side by 8
8y ÷ 8 = 16 ÷ 8
y = 2
----------------------------------------------------------------
y = 2 is your answer

Stuck on question 1, can anyone help???

poizon [28]

'A' is the square root of 25. That's 5, so take A=5 with you
as you go to the next step.

B is A³. A³ means (A x A x A). We know that 'A' is 5, so 'B' is (5x 5 x 5) = 125 .
Take B=125 with you to the next step.

'C' is B - 25. We know that 'B' is 125. So C = (125 - 25) = 100 .
Take C=100 with you to the next step.

'D' is the square root of 'C'. We know that C=100, so D = √100 .
The square root of 100 is 10, so D=10.
Take D=10 with you to the next step .

'E' is D+39. We know that D=10. So E=(10+39) = 49 .
Take E=49 with you to the last step.

'F' is the square root of 'E'. We know that E=49.

Which graph represents y = |xl? A B C D

zheka24 [161]

Answer:

Step-by-step explanation:

The equation represented in the question is the parent absolute value question. If you know the different parent functions, then the answer is obvious because absolute value equations always form a V. However, if you do not do this then you can create a table and plugin values. Plugin numbers like 0, -1, and 1 for X and solve for Y. Finally, graph these points and see what graph best fits. If needed you can also plug in more points.
