Answer:

2. x > 17

3. x ≤ 7

4. a < 4

5. t ≥ -2

Step-by-step explanation:

2). x - 7 > 10

Now we add 7 on both the side of the inequality [Both the side of sign (>) greater than].

x - 7 + 7 > 10 + 7

x > 17

Answer is x > 17

3). 3x ≤ 21

Now we divide by 3 on both the sides of the inequality.

$\frac{3x}{3}$ ≤ $\frac{21}{3}$

x ≤ 7

Answer is x ≤ 7

4) 5a - 2 < 18

(5a -2) + 2 < 18 + 2

5a < 20

$\frac{5a}{5}$

a < 4

Answer is a < 4

5). 2t + 8 ≥ -4(t + 1)

2t + 8 ≥ -4t - 4

2t + 8 - 8 ≥ -4t - 4 - 8

2t ≥ -4t - 12

2t + 4t ≥ -4t + 4t - 12

6t ≥ -12

t ≥ - $\frac{12}{6}$

t ≥ -2

Answer is t ≥ -2

Samantha puts an initial $500 into a savings account. The account has a 4% annual compound interest rate. What is the function t

Licemer1 [7]

I use a bit of a different looking formula.

A(t)=P(1+r/n)^nt

P=amount of money. (500)
r= rate (in decimal. 4%=0.04)
n=number of times per year (1 in this problem)
t=amount of time. (5 years)

Plugged in it looks like this:

A(t)=500 (1+ 0.04/1)^1x5

Then I put it into my calculator like this:

0.04/1+ 0.04

Then add one to the above answer:

0.04+1=1.04

Then raise the above answer to the 1x5:

1.04^5=1.2166......

Then multiply the above answer by 500:

1.2166.... x 500=608.3264512

She has $608 after 5 years.

Hope this helps, let me know if you have any questions.
