3 to the 4th power + 2 ⋅ 5 =
Mandarinka [93]
Hello,

The answer is "x=91".

Reason:

First write the equation:

3^4+2*5=

Now use PEMDAS:

E goes first:

3^4=3*3*3*3=81

81+2*5

M goes next:

2*5=10

81+10=

Now use A:

81+10=91

x=91

If you need anymore help feel free to ask me!

Hope this helps!

A house was purchased for $89,000. After 6 years the value of the house was $101,000. Find a linear equation that models the val
mamaluj [8]

Answer:  y = 2000x + 89000

Step-by-step explanation:

Given that;

initial purchase amount = $89,000

price after 6 years = $ 101,000

years = 6

now

slope = ( 101000 - 89000) / 6

slope = 12000 / 6

slope = 2000

therefore the linear equation that models the value of the house after x years will be;

y = 2000x + 89000
