Answer:

Marsha earned interest = $850

Step-by-step explanation:

Amount deposited = $8500

Time = 2 years

Interest rate = 5% = 0.05

We need to find how much did Marsha earn in interest

The formula use is: $I=P\times r \times t$

Where I is interest earned, P is amount deposited, r is interest rate and t is time.

Putting values and finding interest.

$I=P\times r \times t\\I=8500\times 2\times 0.05\\I=850$

So, Marsha earned interest = $850

Answer:

$\frac{(6q-5)}{(3q+5)}$

Step-by-step explanation:

Given: $\frac{18q^{2}-45q+25 }{9q^{2}-25 }$

Factorizing the numerator and the denominator, we have:

18 $q^{2}$ - 45q + 25 = 18 $q^{2}$ - 30q - 15q + 25

= (3q - 5)(6q - 5)

and

9 $q^{2}$ - 25 = (3q - 5)(3q + 5)

So that,

$\frac{18q^{2}-45q+25 }{9q^{2}-25 }$ = $\frac{(3q-5)(6q-5)}{(3q-5)(3q+5)}$

= $\frac{(6q-5)}{(3q+5)}$

Therefore,

$\frac{18q^{2}-45q+25 }{9q^{2}-25 }$ = $\frac{(6q-5)}{(3q+5)}$

Answer & Step-by-step explanation:

When we see the phrase "rate of change" then it means that we are looking for the slope. So, we will need to know the formula for finding slope or the rate of change.

$slope=\frac{y_2-y_1}{x_2-x_1}$

Now, let's use this equation to solve for the rate of change of each question.

Problem 1:

$Slope=\frac{2-\frac{4}{3}}{0-(-1)}\\\\Slope=\frac{\frac{2}{3}}{1}\\\\Slope=\frac{2}{3}$

The rate of change of this equation is 2/3

Problem 2:

$Slope=\frac{4-2}{1-0}\\\\Slope=\frac{2}{1}\\\\Slope=2$

The rate of change for this equation is 2

Problem 3:

$Slope=\frac{10-4}{2-1}\\\\Slope=\frac{6}{1}\\\\Slope=6$

The rate of change for this equation is 6

Which of the following are equations for the line shown below? Check all that

Maurinko [17]

ANSWER: A & B

FOR COORDINATES (2,2)
A) 2-2=-0.25(2-2)
0=0
B) 2-3=-0.25(2+2)
-1=-1

FOR COORDINATES (-2,3)
A) 3-2=-0.25(-2-2)
1=1
B) 3-3=-0.25(-2+2)
0=0

WHY ITS NOT C and D

COORDINATES (2,2)
C) 2+3=-0.25(2-2)
5=0 ZERO DOES NOT EQUAL 5
D) 2-3=-0.25(2-2)
-1=0 ZERO DOES NOT EQUAL -1

COORDINATES (-2,3)
C) 3+3=-0.25(-2-2)
6=1 SIX DOES NOT EQUAL 1
D) 3-3=-0.25(-2-2)
0=1 ZERO DOES NOT EQUAL 1
