Question:

Expand and simplify 5(x - 1) - 3(x + 4)

Answer:

1.) Use the distributive property to solve this equation:

5(x - 1) = 5x - 5

3(x + 4) = 3x + 12

2.) Put it in the equation:

5x - 5 - 3x + 12

3.) Group them:

5x - 3x - 5 + 12

4.) Simplify:

2x - 7
which is the answer.



Hope this helped! :))

So first it’s 5x-5-3x-12( got this using distributive property)
Now we simplify by combining like terms so 5x-3x=2x
And -5-12=-17
Ending to be 2x-17

. Complete the missing steps in the paragraph proof of Theorem 3-8.
Crank
To solve for the missing steps, let's rewrite first the problem.

Given:

In a plane, line m is perpendicular to line t or  m⟂t
                  line n is perpendicular to line t  or  n⟂t


Required:

Prove that line m and n are parallel lines


Solution:

We know that line t is the transversal of the lines m and n.

With reference to the figure above, 

∠ 2 and ∠ 6 are right angles by definition of <u>perpendicular lines</u>. This states that if two lines are perpendicular with each other, they intersect at right angles.

So ∠ 2 ≅ ∠ 6. Since <u>corresponding</u> angles are congruent. 

Therefore, line m and line n are parallel lines.

Examine the following table. Determine whether the rate of change is constant or variable. If it is constant, state the rate of
xenn [34]

Answer:

Variable rate of change.

Step-by-step explanation:

Plot the points and you'll see that the graph is not a straight line, therefore the rate of change is variable.

The equation 6y = 30 - 8x has solutions of (b, 1) and (a, b).<br> What are the values of a and b?
victus00 [196]

The values of a and b are a = \frac{3}{2} and b = 3, respectively.

In this question we need to solve the linear equation for each point, first for (x,y) = (b, 1) and later for (x,y) = (a, b).

If we know that (x,y) = (b, 1), then the value of b is:

6 = 30-8\cdot b

8\cdot b = 24

b = 3

If we know that (x,y) = (a, b) and b = 3, then the value of a is:

6\cdot b = 30 - 8\cdot a

18 = 30-8\cdot a

12 = 8\cdot a

a = \frac{3}{2}

The values of a and b are a = \frac{3}{2} and b = 3, respectively.
