Answer:

Step-by-step explanation:

Dear Mrs.Rappa,

I don't know much about this but i do know that saving accounts are risky and she should just set up a checking. Because it's proven that you'll take the risk of losing value in your money. And you take a risk, but to help you more i need to know about what the 5% 7 means. if i do know what it's means, but the 5% is good, it's compound interest which means you get more money on that interest It grows, but as far as the 7 goes, IDK. but the saving %"s are good like yay money, but she takes the risks. So why the risk is there is because of the stock market, and also because the bank takes other clients money for them to pay other client's. So a risk in 7yrs.  

                                                       Sincerely,

                                                           First name Last name Here

Answer:

138

Step-by-step explanation:

p(x) = 3x^4 + 2x^3 − 4x^2 + 21

Let x = 2

p(2) = 3*(2)^4 + 2*(2)^3 − 4*(2)^2 + 21

       = 3*16+2*8-4*4+21

       =48+16-16+21

        = 69

This is per girl

There are 2 girls

2 * 69

How do you solve this? x - 2y = 4
valentina_108 [34]
If you want to solve for x, then
add 2y to both sides
x=2y+4
if want to solve for y
minus x both sides and divide by -2
x-2y=4
-2y=-x+4
y=1/2x-2
