Answer:

Is x = 4 a solution to the equation 6 = x + 2? YES

Is x = 4 a solution to the inequality 2x ≥ 9? NO

Step-by-step explanation:

Is x = 4 a solution to the equation 6 = x + 2? YES

we cans solve the equation 6=x+2 by clearing for x:

6 = x + 2

we move the +2 on the right as a -2 to the left:

6 - 2 = x

4 = x

this way we find that indeed x = 4 is a solution to 6 = x + 2.

Is x = 4 a solution to the inequality 2x ≥ 9? NO

Let's solve the inequality by clearing for x:

2x ≥ 9

we move the 2 that is multiplying on the left to divide on the right side:

x ≥ 9/2

x ≥ 4.5   ⇒ <u>x must be greater than or equal to 4.5</u>

thus, <u>4 is not a solution to the inequality</u> because 4 is less than 4.5

Which expressions is equivalent to 2r+(t+r)
azamat

Answer:

t+3r

Step-by-step explanation:

This is a one step solution

All you do is add like terms

In this case the only like terms are the varibles r

2r+(t+r)

so if you add all of the rs together there would be 3rs

So the rest of the problem would continue as normal while bringing the 3r to the end

t+3r

What is the slope of line PQ?
Scilla [17]

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

<u>Part a) Find the slope of line PQ</u>

P(-8,2)\ Q(4,2)

substitute in the formula

m=\frac{2-2}{4+8}

m=\frac{0}{12}=0

Any line parallel to X-axis has slope equal to zero

so

the line PQ is parallel to the x-axis

therefore

<u>the answer Part a) is </u>

0

<u>Part b) Find the slope of line MN</u>

M(8,6)\ N(8,-8)

substitute in the formula

m=\frac{-8-6}{8-8}

m=\frac{-14}{0}

Anything divided by zero is undefined

m=undefined

therefore

<u>the answer Part b) is </u>

undefined

<u>Part c) How are the two lines related ? </u>

we know that

Any line perpendicular to X-axis has slope undefined

Because the term (x2-x1) will always be zero

so

<u>the answer Part c) is</u>

the lines are perpendicular
