We have to use pythagorean theorem. The equation is a^{2} + b^{2} = c^{2} so we plug in the numbers (hypothenuse is always C in the equation) a^{2} + 8^{2} =10^{2} now we solve:

a^{2} +64=100 Exponents 

a^{2} =36 Subtract

a=6 Square Root

What is the solution of the system ? <br> 2x+3y=4 <br> x-y=-3
fgiga [73]
Change the equation, x - y = -3, to isolate x or y and plug that new equation into the equation 2x + 3y = 4

I changed it to: x = y - 3
so 
2(y - 3) + 3y = 4
2y - 6 + 3y = 4
5y - 6 = 4
5y = 4 + 6
5y = 10
y = 10/5
y = 2

then you plug that 2 into the equation x = y - 3 to get the value of x

x = (2) - 3
x = -1

you can check this by plugging the x and y values into the equation 2x + 3y = 4

2(-1) + 3(2) = 4
-2 + 6 = 4
4 = 4

hope this helps :)

Population of a town is 2500 and it grows with a doubling time of 10 years. What will the population be in eight years
alex41 [277]

Answer: I think 4500.

Step-by-step explanation: Since the doubling time is 10 years, which means another 2500 is added. So all we have to do is add 2500*(8/10) plus the original 2500, and here ya go!
