Answer: A) (4, 6)

Step-by-step explanation:

1. You can plot the given points (-2,-2) and (4,-2), as you can see in the first graph attached.

2. The formula for calculate the area of a triangle is:

A=\frac{bh}{2}

Where<em> b</em> is the base and <em>h</em> is the height.

3. As you can see in the first graph, the lenght of the base is:

b=6units

So, you must solve for the heigth:

h=\frac{2A}{b}=\frac{2(24units^{2})}{6units}=8units

3. Add 8 to the y-coordinate of both points given in the problem to know the coordinates of the other vertex:

(-2,-2+8)=(-2,6) (This is not an option)

(4,-2+8)=(4,6) (Option A. This is the answer).

4. Then, the triangle is shown in the second graph.

Match each whole number with a rational, exponential expression. 1. 512 2. 8 3. 343 4. 216 5. 729 6.
Crazy boy [7]

Answer:

1. 2^9 = 512

2. 2^3 = 8

3. 7^3 = 343

4. 6^3 = 216

5. 3^6 = 729

Step-by-step explanation:

To start we have to express the number as a multiplication of prime numbers, from there we can take the expression as a power

1.

2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 512

2^9 = 512

2.

2 x 2 x 2 = 8

2^3 = 8

3.

7 x 7 x 7 = 343

7^3 = 343

4.

6 x 6 x 6 = 216

6^3 = 216

5.

3 x 3 x 3 x 3 x 3 x 3 = 729

3^6 = 729

Georgia’s scores in six subjects are 89, 75, 92, 68, 78, 75, and 80. If she finds a single value that summarizes all the values
posledela
It would be mean. The mean is the average that is you are looking for, since she wants a summerization of all the values in the data set. To find the mean (average) add all the numbers and then divide by the amount of numbers.

Paige was playing a trivia game where you gained points for correct answers and lost points for incorrect answers. At the start
victus00 [196]

Givens

Start = S = - 700

# Correct = C = 8

Value Correct = VC = 400

# Incorrect =I = 9

Value Incorrect =VI =  - 600

Equation

Score = S + C*VC + I*VI         Substitute

Solve

Score = -700 + 8*400 + 9(-600)

Score = -700 + 3200 - 5400

Score = - 700 - 2200

Score = - 2900 <<<<< Answer
