Answer: 9
Step-by-step explanation: You have to use PEMDAS for this equation. First, E for Exponent. 2 to the 3rd power is 8. Then, M for Multiply. 4 times 2 is 8. You then add the two 8’s together. Finally, S for Subtract. 16-7 is 9
Answer: x = 0 or x = 2
Step-by-step explanation:
To solve this, we must note that the two equations speaks of a single function of y. So
y = 2x - 3 = x² - 3
So from.here we can equate the two together and solve for x.
x² - 3 = 2x - 3, biw convert to a quadratic expression
x² - 2x - 3 + 3 = 0
x² - 2x = 0
Now factorize
x( x - 2 ) = 0, so solving for x
x = 0 or x = 2. .I believed getting the 2 won't be a problem
When x - 2 = 0
Then x = 2.
I just did on a calculator, I hope it helped a littler
A/2=b/3
b/a
a=2/3b
b=3/2a
4b/9a
Answer:
x = lillies
y = tulips
x + y = 13
1.25x + .90y = 14.85
-1.25x - 1.25y = -16.25
1.25x + .90y = 14.85
-0.35y = -1.40
y = 4 tulips
x + 4 = 13
x = 9 lillies
(9 lillies, 4 tulips)
