Answer:

y=1-7x

Step-by-step explanation:

7x+y=1

The first thing to do is get the y by its self. So u cancel the 7x out by-7x and bring it to the other side.

7x-7x = 0

Now all we have left is: y=1-7x

Hope it helps and is right.

A pair of sneakers are on sale for 20% off the original price. Tom purchased a pair of sneakers at this discounted price of $80.
LUCKY_DIMON [66]
The answer is 100.
You start by making a formula:
.80(x) = 80,
As we know the discount is 20% off, which makes the price actually 80% of what it originally was. Convert percent to a decimal gets you that .80
Reverse the process — 80/0.80 = 100

a. Suppose we had $15,192 cash and invested it in the bank at 16 percent interest, how much would you have at the end of 1, 2, 3
Goryan [66]

Answer:

Part a) \$17,622.72

Part b) \$20,442.36

Part c) \$23,713.13

Part d) \$27,507.23

Step-by-step explanation:

we know that  

The compound interest formula is equal to

A=P(1+\frac{r}{n})^{nt}

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

Part a) How much would you have at the end of 1 year?

in this problem we have

t=1\ years\\ P=\$15,192\\ r=0.16\\n=1

substitute in the formula above

A=15,192(1+\frac{0.16}{1})^{1*1}=\$17,622.72

Part b) How much would you have at the end of 2 year?

in this problem we have

t=2\ years\\ P=\$15,192\\ r=0.16\\n=1

substitute in the formula above

A=15,192(1+\frac{0.16}{1})^{1*2}=\$20,442.36

Part c) How much would you have at the end of 3 year?

in this problem we have

t=3\ years\\ P=\$15,192\\ r=0.16\\n=1

substitute in the formula above

A=15,192(1+\frac{0.16}{1})^{1*3}=\$23,713.13

Part d) How much would you have at the end of 4 year?

in this problem we have

t=4\ years\\ P=\$15,192\\ r=0.16\\n=1

substitute in the formula above

A=15,192(1+\frac{0.16}{1})^{1*4}=\$27,507.23
