Anything multiplied by zero is zero
Answer:
(-5,-3)
(1,3)
Step-by-step explanation:
Solving with substitution
Set both equations to y = ...
y = x^2 + 5x - 3
----------------
y - x =2
y = x + 2
----------------
Substitute one of the Y's with the other Y = equation.
x + 2 = x ^2 + 5x -3
Set one side to 0
0 = x^2 + 4x -5
x^2 + 4x - 5 = 0
Simplify by factoring
(x-1) (x+5)
Get your X values
x-1 = 0
x = 1
x+5 = 0
x = -5
Plug in each X into one of the equations to get your Y value.
1st X
y = x + 2
y = 1 + 2
y = 3
When X = 1, Y = 3
2nd X
y = x + 2
y = -5 + 2
y = -3
When X = - 5, Y = -3
Your answers are (1,3) and (-5,-3)
-3 1/2 is rational because the decimal ends at -3.5. It is not sqrt(5) because the decimal never ends and the same follows for pi and 9.23157.
Answer:
The regular price for 1 pound of flour was $ 1.29
Step-by-step explanation:
Price Percentage
$ 16.24 90
x 100
***************************
90 * x = 16.24 * 100
90x = 1,624
x = 1,624/90
x = 18.05
Now, let's calculate the price of each bag of flour, this way:
Price of each bag = 18.05/7
Price of each bag = $ 2.58 (rounding to the next cent)
Finally, we can calculate the regular price for 1 pound of flour:
Regular price for 1 pound of flour = 2.58/2
Regular price for 1 pound of flour = $ 1.29
