Solve the following system of equations and show all work. y = x^2 + 3 y = x + 5

1 answer:

7 0

Since both of the equations are equal to y...set them equal to each other.. So it will then be

x^2+3=x+5
-3 -3
x^2=x+2 ---> x^2-x-2
(x-2) (x+1)
x=2,-1

Answer:C) She would have $216.88.

Step-by-step explanation:

A) Deposits: +34.98; +51.02; +51.22

Withdrawals: -5.23; -5.22; -7.89

B) -7.89, -5.23, -5.22, +34.98, +51.02, +51.22

The smallest amount will be the largest withdrawal, as it takes away from the account; the largest amount will be the largest deposit, as it adds to the account.

98 + 34.98 = 132.98 + 51.02 = 184.00 + 51.22 = 235.22 - 7.89 = 227.33 - 5.23 = 222.10 - 5.22 = 216.88

An easy way to test this is with the equation $A^{2}+B ^{2}=C ^{2}$ this means that if you add 4.8²+6.4² does it equal 8²? if so then it is a right triangle. This is called the Pythagorean theorem. So the answer is, yes it is a right triangle.
