Step-by-step explanation:

(Please I will mark BRAINLIEST, not lie)Use this equation to solve for the missing variable:
y = 8x + 12

If x = -6, y = _____

If y = 13, x = _____

Answers

y = 8x + 12

if x = -6

y = 8(-6) + 12

y = -48 + 12

y = - 36

if y = 13

13 = 8x + 12

13-12 = 8x

8x = 1

x = ¹/₈ ≈ 0.125

Answer:

If x = -6, y = -36

If y = 13, x = [tex]\frac{1}{8}[/tex]

Step-by-step explanation:

There is one equation and are asked to find x and y if there is a certain value to substitute either x or y.

Let's start with x, we know that x = -6. Meaning that we need to subtitute x for -6. Do as followed :

y = 8(-6) + 12

y = -48 + 12

y = -36

Now do y, we know that y is 13. Meaning that we need to substitute y for 13. Do as followed :

8x + 12 = 13

We need to isolate x alone, so do as followed :

Subtract 12 from both sides to get 8x alone :

8x = 1

Divide 8 from both sides to get x alone :

x = 1/8

Find A, B so that y = A sin(2) + B cos(2) is a solution to the differential equation

A=
BE
Submit Question

Answers

If y = A sin(x) + B cos(x), then

y' = A cos(x) - B sin(x)

y'' = -A sin(x) - B cos(x)

Substitute these into the ODE:

4y'' + y' + 5y = 2 cos(x)

4 (-A sin(x) - B cos(x)) + (A cos(x) - B sin(x)) + 5(A sin(x) + B cos(x)) = 2 cos(x)

(-4A - B + 5A) sin(x) + (-4B + A + 5B) cos(x) = 2 cos(x)

(A - B) sin(x) + (A + B) cos(x) = 2 cos(x)

Then

A - B = 0

A + B = 2

Adding these equation gives

(A - B) + (A + B) = 0 + 2

2A = 2

A = 1 → B = 1

= 3x(3x + 2).

Answer: 3x(3x + 2)

Solution:

(4x2 - 2x) - (-5x2 - 8x)

= 3x(3x + 2).

Answer: 3x(3x + 2)

Solution:
