10 POINTS Solve the combined inequality: 6 -2x < 12 or 7 + 2x < -11

1 answer:

8 0

The first thing we must do in this case is to solve both inequations.
We have then:
Inequality 1:
6 -2x <12
6-12 <2x
-6 <2x
-6/2 <x
-3 <x
Inequality 2:
7 + 2x <-11
2x <-11-7
2x <-18
x <-18/2
x <-9
Answer:
(-inf, -9) U (-3, inf)

A satellite travels from Earth to the moon (238,905 miles), then from the moon to Mars (48,340,732 miles) and finally from Mars

hodyreva [135]

The total distance the satellite traveled in all is 120,528,469 miles

<h3>Calculating total distance</h3>

From the question, we are to determine how far the Satellite traveled in all

From the given information,

A satellite travels from Earth to the moon (238,905 miles),

and

It traveled from the moon to Mars (48,340,732 miles)

and

It finally traveled from Mars to Venus (71,948,832 miles)

The total distance the satellite traveled in all = 238,905 miles + 48,340,732 miles + 71,948,832 miles

∴The total distance the satellite traveled in all = 120,528,469 miles

Hence, the total distance the satellite traveled in all is 120,528,469 miles

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 4 h, and Car B traveled the dista

poizon [28]

The rate of Car A is x
The rate of Car B is x - 5

They travel the same distance. So we can make an equation:

4(x) = 4.5(x-5)

Solve for x.

4(x) = 4.5(x-5)
4x = 4.5x - 22.5

Subtract 4.5x on both sides

-0.5x = -22.5

Divide by -0.5 on both sides
x = 45

But we want the speed of Car B which is x - 5

So Car B's speed is 45 - 5 = 40

Your answer is 40

What is the equation of the points (-3,2) (2,-1) in standard form?

Evgen [1.6K]

You can just plug in one of the points to each equation until you get an equality that is true.

I chose to use (-3,2)

1. 5x+3y=1
5(-3)+3(2)=1
(-15)+ 6 = 1
(-9) = 1 <<<(FALSE)

2. x+5y=3
(-3)+5(2)= 3
(-3)+10= 3
7=3 <<<(FALSE)

3. 3x+5y=1
3(-3) + 5(2)= 1
(-9)+10=1
1=1<<<(TRUE)

So, the correct equation is 3x+5y=1.

Make sense?

Graph A represents the exponential equation y=4(6) and graph B represents y=6(4). which statements are true about graph a and gr

PtichkaEL [24]

Answer:

Step-by-step explanation:The following statements are true about exponential functions:

-The domain is all real numbers.

- The input to an exponential function is the exponent.

- The base represents the multiplicative rate of change.

The reason why the other two options are wrong are explained below:

The range of exponential functions is not always includes negative numbers; on the contrary, the range is the set of all positive real numbers.

The graph of an exponential function does not have a horizontal asymptote at x = 0; contrarily, the equation of the horizontal asymptote of the graph of is y = 0, which is the x-axis.
