Steps to solve:

x + x + 2 + 2x = -2

Combine Like Terms:

(x + x + 2x) + 2 = -2

Simplify.

4x + 2 = -2

Subtract 2 to both sides.

4x + 2 - 2 = -2 - 2

Simplify.

4x = -4

Divide 4 to both sides.

4x/4 = -4/4

Simplify.

x = -1

tankabanditka [31]

Answer:

8 < x < 34

Step-by-step explanation:

ab = 13, ac = 21, bc = x

The longest side of a triangle must be less than the sum of the other two sides.

If 21 is the longest side:

21 < 13 + x

8 < x

If x is the longest side:

x < 13 + 21

x < 34

Therefore, 8 < x < 34.

Tyrone has $500 in his savings account. He wants to save more money. He is looking at two investment plans. Under plan A, he wil

Marrrta [24]

Answer:

$\$522.78$

Step-by-step explanation:

Let

x ---> the number of years

y ---> the amount in the account balance

Plan A

we have a linear equation of the form

$y=mx+b$

where

The slope is equal to

$m=\$100\ per\ year$

The y-intercept or initial value is

$b=\$500$

substitute

$y=100x+500$

For x=10 years

substitute

$y=100(10)+500=\$1,500$

Plan B

we have a exponential growth function of the form

$y=a(1+r)^x$

where

$a=\$500\\r=15\%=15/100=0.15$

substitute

$y=500(1+0.15)^x$

$y=500(1.15)^x$

For x=10 years

substitute

$y=500(1.15)^{10}=\$2,022.78$

Find the difference of the two account balances after 10 years

$\$2,022.78-\$1,500=\$522.78$
