Intercepts:
Tema [17]
An x-intercept is the point where the function passes the x axis at y=0.
The y-intercept is the point where the function crosses the y axis at x=0

1. It is an x-intercept, so y = 0. The ordered pair would be (-6, 0)
2. It is a y-intercept, so x = 0. The ordered pair would be (0, -2.3)
3. It is a y-intercept, so x=0. The ordered pair would be (0, 3/4)

To find the x-intercept, set y = 0. To find the y-intercept, set x=0

4. y-intercept: y = 3(0) -9. y = -9 The y-intercept is at (0, -9)
x-intercept: 0 = 3x -9. 9 = 3x. x = 3. The x-intercept is at (3, 0)

5. x intercept: 0 = 5x +10. -10 = 5x. x = -2. The x-intercept is at (-2, 0)
y-intercept: y = 5(0) + 10. y = 10. The y-intercept is at (0, 10)

If you look at finding the y-intercepts in the two problems above, you may see there is a pattern forming. The y-intercept is the number that your adding or subtracting that is located after the x (ex. y = 4x - 2 - the y-intercept would be -2)

9. First, find the x and y-intercepts. The y intercept is -3 You’d graph that at (0, -3). 0 = -1/2x - 3. -1/2x = 3. x = -6 so the x-intercept is at (-6, 0). If you only need to graph 2 points, then you can graph just those two points and draw a line between them.

To graph y=-1/2x + 3, start at the y-intercept and use the slope (-1/2) to find other points. Because your slope is -1/2, you’d go down 1 unit and then to the right 2 units. That would be your next point. If you wanted your line to go further up, go up one unit and then to the left 2 units. That would be your next point.

I am not sure what you need to do on 11 and 12

I think you should try 7, 8 and 10 on your own and let me know if you have any questions on them or if you are stuck on anything.

5. Last year, Dan and Paula regularly invested $25/week in a mutual fund account. This
kozerog [31]

Answer:

They invested total $2730 over the past two years.

Step-by-step explanation:

Consider the provided information.

Dan and Paula regularly invested $25/week in a mutual fund account.

There are 52 weeks in a year.

Total money they invested in a mutual fund in first year.

$25×52 = $1300

They increased their weekly investment by 10 percent.

First find the 10% or 25.

\$25\times \frac{10}{100}=\$2.5

That means they invest $25+$2.5 = $27.5

They invest $27.5/week in next year.

Total money they invested in a mutual fund in second year.

$27.5×52 = $1430

Hence the total money they invested in the account over the past two year is:

$1300+$1430=$2730

Hence, they invested total $2730 over the past two years.
