Solve the equation. 5x + 6 = 2(2x – 3) what dose x =

Lady_Fox [76]

Answer:

x=−12

Step-by-step explanation:

Let's solve your equation step-by-step.

5x+6=2(2x−3)

Step 1: Simplify both sides of the equation.

5x+6=2(2x−3)

5x+6=(2)(2x)+(2)(−3)(Distribute)

5x+6=4x+−6

5x+6=4x−6

Step 2: Subtract 4x from both sides.

5x+6−4x=4x−6−4x

x+6=−6

Step 3: Subtract 6 from both sides.

x+6−6=−6−6

Which of the following is the best definition of vertical angles?

Lilit [14]

Step-by-step explanation:

Very quick and effortless example of vertical angles in the attached image. When 2 straight lines intersect, the 2 angles opposite each other at that point are vertical angles, and they are always congruent.

I'd say it's the 3rd option:

"Vertical angles are a pair of non-adjacent angles formed by two intersecting lines."

but any of the first three could be technically true really. Adjacent angles are 2 angles that share a side, and vertical angles cannot share one.

The slope of the line is ___. (Simplify your answer. Type an integer or a fraction.)

bonufazy [111]

Answer:

-5/7

Step-by-step explanation:

Look at the graph. As we move from left to right from (-3, 2) to (4, -3), x increases by 7 and y decreases by 5. Thus, the slope is

m = rise/run = -5/7.

PLEASE HELP HYPERBOLAS What is the length of the transverse axis ? (x-1)^2/25-(y+3)^2/9=1

Sav [38]

Given equation of hyperbola is

$\frac{(x-1)^{2}}{25}-\frac{(y+3)^{2}}{9}=1$

Given hyperbola is the horizontal hyperbola

The standard form of the horizontal hyperbola is

$\frac{(x-h)^{2}}{a^{2}}-\frac{(y-k)^{2}}{b^{2}}=1$

When we compare these two equations, we get

h = 1, a = 5 , k = -3 and b = 3

Length of the transverse axis = 2a

Plug in the value of 'a' as 5

So,Length of the transverse axis = 2(5) = 10
