final number should be divisible by 10.

x=7

2.50 or 2.5

Step-by-step explanation:

1/4=.25 so 25% of a number=5/8=0.625

.625*4=2.50 or 2.5

Your 2 year investment of $5,300 earns 2.9% and is compounded annually. What will your total return be?

Answers

The total return will be $5611.8

How to calculate the total return?

A 2 year investment of $5,300 earns 2.9%

The investment is compounded annually

The total return can be calculated as follows

= 5300 (2.9/100 + 1)

= 5300 (0.029 + 1)

= 5300(1.029)²

= 5300(1.0588)

= $5611.8

Hence the total return is $5611.8

plsss help me with this:(((​

Answers

Answer:

First we need our slope equation

Y₂-Y₁/X₂-X₁

So we have our equation now lets plug it in

-9+2/-4-3 (we make it a plus for -9+2 because the two minuses cancel out).

So now we have -7/-7 which is 1 because -7 divided by itself is one. Thereby your answer is A. 1

Same thing for question 12

1-5/2-4

-4/-2 which is 2 because -2 goes into -4 two times so your answer is A. 2

Is each line parallel, perpendicular, or neither parallel nor perpendicular to the line 4x + 3y = 12? Drag and drop each choice into the boxes to correctly complete the table. Parallel Perpendicular Neither

Answers

Step-by-step explanation:

The line given:

4x + 3y = 12, its slope is m = - 4/3

Other lines to compare:

-3x + 4y = 8, the slope is m = 3/4, it is perpendicular line as the product of the slopes is  - 1;4x + 3y = 31, the slope is m = -4/3, same slope but different y- intercept, it is parallel line;3x + 4y = 12, the slope is m = -3/4, it is neither parallel nor perpendicular;-4x + 3y = - 1, the slope is m = 4/3, it is neither parallel nor perpendicular
4x+3y=123y=-4x+12y=-4/3x+12

Slope=m=+4/3

#1

-3x+4y=8

m=3/4

Perpendicular

#2

4x-3y=31

m=-4/3

Parallel

#3

3x+4y=12

m=-3/4

neither

#4

-4x+3y=-1

m=4/3

Neither

The inequality represent the given graph is y≤7 . Therefore, option B is the correct answer.

What are inequalities?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

From the given graph, the line passes through (0, -7)

In the given graph the inequality is y≤7

Therefore, option B is the correct answer.
