Answer:

there is no solution

Step-by-step explanation:

Expand.

15x+35+2x=7x+10x-4515x+35+2x=7x+10x−45

2 Simplify 15x+35+2x15x+35+2x to 17x+3517x+35.

17x+35=7x+10x-4517x+35=7x+10x−45

3 Simplify 7x+10x-457x+10x−45 to 17x-4517x−45.

17x+35=17x-4517x+35=17x−45

4 Cancel 17x17x on both sides.

35=-4535=−45

5 Since 35=-4535=−45 is false, there is no solution.

Find the equation of the line with m = 2 and passes through the point ( 4 , − 5 ) . Write your answer in standard form A x + B y

Rudiy27

Answer:

2x - y = 13

Step-by-step explanation:

To write the equation of a line use the formula $y - y_1 = m(x-x_1)$ .

Substitute m = 2 and (4,-5).

$y --5 = 2(x-4)\\y + 5 = 2(x - 4)\\y + 5 = 2x - 8\\y = 2x -13\\-2x + y = -13\\2x - y = 13$

Wanda placed $100 in a savings account that pays 2% simple interest per year. After 6 months Wanda made another deposit of $100.

STatiana [176]

Answer:

$\$203.01$

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

<em>After 6 months</em>

$t=6/12=0.5\ years\\ P=\$100\\r=2\%=2/100=0.02$

substitute in the formula above

$A_1=100(1+0.02*0.5)$

$A_1=100(1.01)$

$A_1=\$101$

$t=6/12=0.5\ years\\ P=A_1+\$100=\$101+\$100=\$201\\r=2\%=2/100=0.02$

substitute in the formula above

$A_2=201(1+0.02*0.5)$

$A_2=201(1.01)$

$A_2=\$203.01$
