13. m = -1

14. y-intercept = 2

Step-by-step explanation:

Questions #1, 4, 7, 10, 13:

These questions are the ones looking for the slope. To find the slope with the equation, all you have to do is look at the coefficient to the "x".

Questions #2, 5, 8, 11, 14:

These questions are the ones looking for the y-intercepts. To find the y-intercept of the equation, all you have to look for is the other term (not the one with "x"). It will generally be the second one in the equation.

Questions #3, 6, 9, 12:

These questions are the ones asking you to graph them. To find two coordinates to place (and then connect the dots to form the line), you can use the y-intercept and the slope. The y-intercept alone can count as one. Then you must look at the formatting of the slope.

The numerator of the slope is how much a point rises and the denominator is how much is runs. For example, if you have the coordinate (4,5) and the slope is 1/2, you would rise one and go run over two, so another coordinate would be (6,6)

16. Find the final balance in an account with $730 invested at 3% annual simple interest for 4 years. (1 point) $735.48 $87.60 $

podryga [215]

Answer:

$817.60

Step-by-step explanation:

Simple interest has the formula:

Simple Interest = Principal * rate * time

here,

Principal amount is $730

The rate of interest is 3%, which is 3/100 = 0.03

The time length in years is given as 4

We find the interest amount first:

SI = P * r * t

SI = 730 * 0.03 * 4

SI = 87.6

We are asked to find FINAL BALANCE, which is PRINCIPAL + INTEREST

So,

Final Balance = 730 + 87.6 = $817.60

Answer:

Step-by-step explanation:

First, you gotta work out the hypotenuse of ABC, which is AC.

To do that, you need to figure out the scale factor between the two right-angled triangles. You can do that for this question because this is a similar shapes question.

12.5/5 = 2.5

The scale factor length between the two triangles is 2.5.

You can use 2.5 now to work out AC, so AC would be 13 x 2.5, which gives 32.5.

Now that you've got the hypotenuse and BC of ABC, you can use Pythagoras's theorem to work out the length of AB

Pythagoras's theorem = $a^2 + b^2 = c^2$
