Answer:

1. (-4,0) and (-2,0)

2. (2,0)

3. (2,0)

4. (-6,0), (-2,0), (2,0), and (6,0)

Step-by-step explanation:

The x-intercepts are the points in which the line crosses the x-axis. Another word for this are the zeroes, because y=0 would be right on the x-axis, and finding the zeroes would be finding the points that cross y=0. Notice how the points listen on the answer are right on the x-axis of each graph; they intercept the x-axis.

What is the missing value of 5x-2y=30 (8,)

AnnZ [28]

Answer:

In this equation, we can start by understanding that "x" has a value of 8, as given in the ordered pair. When multiplied by 5, this leads to "40 - 2y = 30". Next, we can subtract 40 from both sides of the equation. This leads us to a value of "-2y = -10". The next step would be to divide both sides by -2 as a way of isolating "y", which leads us to a final value of "y = 5". The final ordered pair would be (8,5).

A value of a car is $24,000. You pay it off by making payments of $6200 a year. Write and equation for when the car would be pay

Damm [24]

Answer: 24,000 / 6,200 = x years

Step-by-step explanation:

The car is valued at $24,000.

Yearly payments are $6,200.

The year that it will be paid off can be dtermined by calculating how long it would take $6,200 to get to $24,000.

You can do that by dividing $24,000 by $6,200.

Assume the number of years for the car to be paid off is x:

24,000 / 6,200 = x years
