Answer: x = -7

Step-by-step explanation:

4(1 - x) + 2x = -3(x + 1)

First, use distributive property

4 - 4x + 2x = -3x + -3

Combine like terms

4 - 2x = -3x - 3

Add 3x to each side

4 + x = -3

Subtract 4 from each side

x = -7

Answer:

-2

<h2>Step-by-step explanation:</h2>

1. Equation at the end of step 1  ((4•(1-x))+3x)-(0-2•(x-1))  = 0

2. Equation at the end of step 2 (4 • (1 - x) +  3x) -  -2 • (x - 1)  = 0

3. Equation at the end of step 3  x + 2  = 0

4. End of equation Solve  :    x+2 = 0

What is the equation of the line that passes through the point (-5,-2) and has a slope of 3/5?
SOVA2 [1]

Answer:

y = 3/5x + 1

Step-by-step explanation:

Formula:

y - y1 = m(x - x1)

Plug in:

y - (-2) = 3/5(x - (-5))

Two negatives make a positive:

y + 2 = 3/5(x +5)

Distribute 3/5 to (x + 5):

y + 2 = 3/5x + 3

Get y by itself by - 2:

y = 3/5x + 1

Hope this helps you :)

Number line for-5 c &lt;-30 the sign also has a line under it
Eddi Din [679]
If you are solving for c you need to divide both sides of the inequality by -5 so c< (or equal to) -30/-5 or c<(or equal to)7

Hey! Apologies that I can’t make this look nice because I’m on mobile.

To simplify this, we can multiply the denominator by its conjugate. For a imaginary function (a+bi), its conjugate would be (a-bi), so we can apply that here to multiply both sides by (2-i)/(2-i). This works because it simplifies to one. Then, we have our fraction as 4*(2-i)/((2-i)(2+i))=(8-4i)/(4-i^2)=(8-4i)/5

Feel free to ask further questions, and have a great rest of your day!

What does a=? b=? Angle B=?
Kobotan [32]

Answer:

If you were solving the right triangle, it would be:

m∠A = 46°

m∠B = 44°

m∠C = 90°

AB = 32

BC ≈ 23

AC ≈ 24

Step-by-step explanation:

To solve this right triangle, you can use trigonometric ratios to solve for the sides. To find the angle measures:

m∠A = 46° (given)

m∠B = x

m∠C = 90° (given)

180 - (46 + 90) = x

180 - 136 = x

44 = x

m∠B = 44°

To find the side measures, you can use tangent, sine, cosine, and the Pythagorean Theorem.

Recall that:

tangent = opposite side/adjacent side

sine = opposite side/hypotenuse

cosine = adjacent side/hypotenuse

So:

sin46 = BC/32

BC = 32 (sin46)

BC ≈ 23

tan46 = BC/AC

AC = BC/tan46

AC = (23.01887361...) (tan46)

AC ≈ 24
