Solve for 2.<br> -9x +5 &lt; 17 AND<br> 13x + 25 &lt; -1
Elena L [17]

Answer:

no solution

Step-by-step explanation:

-9x +5 < 17 AND   13x + 25 < -1

Solve each part separately and then put back together

-9x +5 < 17

Subtract 5 from each side

-9x+5-5< 17-5

-9x < 12

Divide each side by -9 remembering to flip the inequality

-9x/-9>12/-9

x > -4/3

and

13x + 25 < -1

subtract 25 from each side

13x +25-25 < -1-25

13x <-26

Divide by 13

13x/13 < -26/13

x <-2

There is no overlap so there is no solution

Sunny_sXe [5.5K]

Answer:

\$286.00

Step-by-step explanation:

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=1\ years\\ P=\$275.00\\r=4\%=4/100=0.04

substitute in the formula above

A=275.00(1+0.04*1)

A=275.00(1.04)

A=\$286.00
