8 0

Add like terms on the same side:
-10 + 8x = -56
Add ten to both sides
-10 + 8x + 10 = -56 +10
Simplify:
8x = -46
Divide both side by 8
8x/8 = -46/8
Simplify
x = - 5.75
The answer is x = -5.75
(The answer can also be written as -23/4 or -5 3/4)

Let's solve your equation step-by-step.−10+3x+5x=−56
Step 1: Simplify both sides of the equation.
8x−10=−56
Step 2: Add 10 to both sides.
8x−10+10=−56+108x=−46
Step 3: Divide both sides by
8.8x8=−468
x=−23/4

Lorico [155]

Answer:

A) reﬂection of P across the x-axis is at (3, 4).

Step-by-step explanation:

The relevant transformations are ...

(x, y) ⇒ (x, -y) . . . . . . reflection across the x-axis

(x, y) ⇒ (-x, y) . . . . . . reflection across the y-axis

A) sign of y-coordinate has changed: reflection across the x-axis

B) signs of both coordinates have changed: reflection across both axes

C) sign of x-coordinate has changed: reflection across the y-axis

D) sign of y-coordinate has changed: reflection across the x-axis

The only answer choice that has a proper description is Choice A.

If i^2=-1 and (4+2i)(6-ki)=30, what is the value of k?

ZanzabumX [31]

I^2 = -1
i = √-1

Substitute the value of i in the equation:
(4+2i)(6-ki)=30
{4 + (2)(√-1)} {6 - k (√-1)} = 30
( 4 + 2√-1)(6 -k√-1) = 30
24 - 4k√-1 + 12√-1 -2k (-1) =30
24 - 4k√-1 + 12√-1 +2k =30
-4k√-1+12√-1 + 2k - 6 =0
-2√-1(2k -6) + (2k-6) =0
(-2√-1 +1)(2k-6)=0

2k -6 =0
2k = 6
k= 3

So, the value of k is 3.

julsineya [31]

The volume of the prism is 31.25 cm cubed.
Therefore the container has a higher volume.
35 - 31.25 is 3.75.
The difference is 3.75
