What are the first four terms in the multiplication, or geometric, pattern in which the first term is 7 and then each term is multiplied by 4?7, 28, 112, 448

7, 28, 56, 112

7, 11, 15, 19

28, 112, 448, 1792

Answers

Answer 1
Answer: They tell you that the first term is 7 so that cancels out the last answer choice immediately. Then they tell you that each term is multiplied by 4 so when you multiply 7x4 you get 28. This cancels out the second to last answer. Then keep multiplying by 4. 28x4 is 112. 112x4 is 448.
Therefore, the obvious answer is the first choice!
7, 28, 112, 448

Can somebody help me solve Y=9X+6

Answers

Y=9X+6 (You want to shift everything but the x to the other side right?)
So -6 and you have to do the same to each side which makes:

Y-6=9X

Then to leave the x by itself you need to reserve what you've done again so divide both sides by nine to make/

Y-6/9=X

Hope that made sense!!
Y=9x+6
-6=9x (-6)
-6/9=x

Carly bought a new house for $125,000. The value of the house appreciates approximately 3.5% each year. What will be the value of the house after 10 years?

Answers

This problem can be solved using the formula for interest which is: F = P (1 + i)^n where:

F = future value
P = principal value
i = interest per year
n = interest period

Since we are already provided with the values of each, direct substitution should be done. This is shown below:

F = P(1 + i)^n
F = 125000(1 + 0.035)^10
F = 176324.85

Therefore, the value of the house after 10 years will be $176,324.85

What is the slope of the line that contains the points (8, 3) and (8, 7)?a. 4
b. -1/4
c. 0
d. The slope is undefined.

Answers

The slope can be obtained by (y2 - y1) / (x2 - x1).  In this example, using the two points, we have
(7 - 3) /  (8 - 8 ) = 4 / 0.
Division by 0 is undefined.
So, the answer is (d) The slope is undefined.

3/4z-1/3=2/3z+1/5

Answers

3/4z - 1/3 = 2/3z + 1/5
3/4z - 2/3z = 1/5 + 1/3
9/12z - 8/12z = 3/15 + 5/15
1/12z = 8/15
z = 8/15 * 12
z = 96/15 = 32/5 or 6 2/5

Answers

Answer: x = 3/4

Step-by-step explanation:

4x + 9 = 12

     - 9   - 9

4x = 3  Divide by 4 on both sides.

x = 3/4

Answer:

x = 3/4

Step-by-step explanation:

4x + 9 = 12

Step 1. subtract 9 from both sides

4x + 9 = 12

     - 9     - 9

4x = 3

Step 2. divide by 4 to isolate x

4x = 3

/4     /4

x = 3/4
