Answer:

A. P = 9x + 2

Step-by-step explanation:

Perimeter is all the sides lengths added together.

Step 1: Set up equation

P = 2x - 6+ 2x + 1 + 2x + 3x + 7

Step 2: Combine like terms

P = 9x + 2

An investor invested a total of $2500 in two mutual funds. One fund earned a 5% profit while the other earned a 3% profit. If th

7nadin3 [17]

Answer:

$500 and $2000

Step-by-step explanation:

Let x represent the total investment = $2500

also, this total is split into two different funds

Lets represent these funds as a and b, such that fund a yields a profit of 3% and fund b yield a profit of 5%

So,

a + b = x

a + b = 2500 ......eq 1

Profit from each fund gives;

0.03 a + 0.05b = 115 ....eq 2

Solve simultaneously using substitution method

From eq 1;

b = 2500 - a

Slot in this value in eq 2

0.03a + 0.05 (2500 - a) = 115

expand

0.03a + 125 - 0.05a = 115

collect like terms

0.03a - 0.05a = 115 - 125

-0.02a = -10

Divide both sides by -0.02

a = $500

Put this value of a in eq 1

500 + b = 2500

Subtract 500 from both sides

b = 2500 - 500

b = $2000

Find an equation for the line with undefined slope and passing through the point 9, -7

serg [7]

recall, slope = rise/run, and that a fraction is undefined when the denominator is 0, meaning this slope has a run = 0.

to make it short, when the slope is undefined, is a flag that we simply have a vertical line. Check the picture below.
