Answer:

Answer:

x=16, y=-12. (16, -12).

Step-by-step explanation:

5x-16y=272

y=(64-7x)/4

------------------

4y=64-7x

4y+7x=64

5x-16y=272

---------------------

4(4y+7x)=4(64)

5x-16y=272

-----------------

16y+28x=256

5x-16y=272

------------------

33x=528

x=528/33

x=16

5(16)-16y=272

80-16y=272

16y=80-272

16y=-192

y=-192/16

y=-12

How do you find the surface area of a prism

You find the area of each side and add it all together.

l=length h=height b=base

rectangle/square: 2(lxh)+2(hxb)+2(bxh)

l=length h=height b=base

rectangle/square: 2(lxh)+2(hxb)+2(bxh)

Two number cubes are rolled. What is the probability that the first lands on 2 and the second lands on a number greater than 4?

Well you need to find both probabilities first:

Landing on 2:

Landing on a number GREATER than 4:

Then multiply them together

So the probability of the two dice landing within those specific requirements is

Hope this helps!

find the equation of the line which passes through the midpoint of P(2,3)and F(-3,4) and parallel to 2x+y+5=0

Y=-2x-5

(-.5,3.5)

Y-3.5=-2(x+.5)

Y-3.5=-2x-1

Y=-2x+2.5 is the equation of the line

(-.5,3.5)

Y-3.5=-2(x+.5)

Y-3.5=-2x-1

Y=-2x+2.5 is the equation of the line

James invests $20,000 in an account that offers a compound interest rate of 8.3% per year. Which of the following is the correct equation for how much

James will have after 6 years?

Answer:

Step-by-step explanation:

Let y represents the amount James have after 6 years,

Given,

Principal amount, P = $ 20,000,

Compound rate of interest per year, r = 8.3 %,

Thus, the amount after x years would be,

Therefore, the amount after 6 years would be,

Which is the correct equation that represents the amount, James will have after 6 years.

James will have $32,270.13 after 6 years
