Answer:

D. The checking account is overdrawn by $15.

Step-by-step explanation:

Since the balance on a checking account represents the remaining money left in that checking account, having a negative value for that would mean an overdrawing of money, or drawing more money than is in that account in the first place.

Therefore, the answer would be that the checking account is overdrawn by $15.

Chantel drew a picture of her dog on a piece of paper that is 12 centimeters long. She used a copy machine to enlarge her drawin

Georgia [21]

Answer:

a(n)=1.15[a(n-1)]

Step-by-step explanation:

we know that

$115\%=115/100=1.15$

Let

a0 -----> the length of the original copy

The first copy is equal to

a1=1.15(a0)

The second copy is

a2=1.15[1.15(a0)] or a2=1.15[a1]

The third copy is

a3=1.15{1.15[1.15(a0)]} or a3=1.15[a2]

therefore

A recursive formula will be

a(n)=1.15[a(n-1)]

Raise 5 to the power of 3

rewrite i9 as (i^4)2^i

so, you get 125((i^4)^2i)

i^4=1

125(1^2i)

Evaluate 2/ 3 ÷ 4 /5 Give your answer as a fraction in its simplest form.

gulaghasi [49]

Step-by-step explanation:

Our problem:

$\frac{2}{3} \div \frac{4}{5} = unknown$

How to solve?

Find the reciprocal (opposite) of 4/5, then multiply. Simplify if necessary.

Find the reciprocal:

$\frac{2}{3} \times \frac{5}{4} = unknown$

Multiply:

$\frac{2}{3} \times \frac{5}{4} = \frac{10}{12}$

Simplify:

$\frac{10 \div 2}{12 \div 2} = \frac{5}{6}$

5/6 is your answer.

What is the slope of the line that passes through the points (-2, 2), and (-4, -2)? - 2 -2

dusya [7]

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-2, 2) and (-4, -2). Substitute:

$m=\dfrac{-2-2}{-4-(-2)}=\dfrac{-4}{-2}=2$

<h3>Answer: the slope = 2</h3>
