Pretty sure it's C. The division property of equality.

Because on the last step, you divide 9d by 9, to get d. And you also have to divide the other side by 9.

Answer:

D.

the addition property of equality

Step-by-step explanation:

Given the expression in

Step 2: 9d - 5 = -15

The addition property of equality was used to get step 3.

That is

9d - 5 = -15

Move -5 over the equality sign and it becomes +5

9d = -15 + 5

9d = -10

OR add 5 to both sides of the equation as shown below

9d - 5 +5 = -15 + 5

9d = -10 which we have in step 3

The coordinates of rhombus ABCD are A(–4, –2), B(–2, 6), C(6, 8), and D(4, 0). What is the area of the rhombus? Round to the nea
Gekata [30.6K]

Answer:

Brainleist!!!!

Step-by-step explanation:

First calculate the distance between B and D, A and C. 

We have the distance between B and D will be:  sqrt[(x2-x1)^2+(y2-y1)^2] = 8.5

The distance between A and C will be: 14.14 

We have the area of rhombus: 1/2 * 8.5 * 14.14 = 60 square units.

Answer:

a. What is the slope of the line?

y = -3x-3

b. What is the x-intercept of the line? (Where does the line cross the x-axis?)

(-1,0)

c. What is the y-intercept of the line? (Where does the line cross the y-axis?)

(0, -3)

Step-by-step explanation:

Calculate slope:

m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{-3-0}{0-(-1)} \\m = \frac{-3}{1}\\m = -3

Calculate y-intercept:

<em>(Pick any point that lies on the line)</em>

<em />(-1,0)

b = y - (mx)\\b = 0 - (-3 * -1)\\b = 0 - (3)\\b = -3

Create function:

y = -3x-3

Get x-intercept:

<em>Set y = 0:</em>

<em />0 = -3x-3\\3 = -3x\\-1 =x

(-1,0)

Get y-intercept:

<em>Set x = 0:</em>

y = -3x-3\\y = -3 * 0 -3\\y = 0 - 3\\y = -3

(0, -3)

What does that mean
aivan3 [116]

The question is asking you to find the result when you square root 256.

The symbol of a square root is √

If ² is a square symbol, √ is the one that will convert the number back to it's non-squared form.

You normally can't do this without the calculator.

In this question, √256 = 16
