X^2 - 7x + 12 = 0
x^2 - 4x - 3x + 12 = 0
x (x - 4) -3 ( x - 4) = 0
(x - 4) (x - 3) = 0
x = 3 , 4
Check the answer by plugging in 3 and 4 for x, if the equation equals zero then you have your answer.
The problem is asking you to solve the equation
<em>y</em> = 12<em>x</em> + <em>n</em>
for the variable <em>n</em>. To do this, subtract 12<em>x</em> from both sides:
<em>y</em> - 12<em>x</em> = (12<em>x</em> + <em>n</em>) - 12<em>x</em>
<em>y</em> - 12<em>x</em> = <em>n</em>
Let
x-----------> <span>this week's allowance
we know that
(3/4)x-----------> </span><span>was spent on candy
and
(5/6)[</span>(3/4)x]-------> <span>was spent on gummy bears
(5/6)*(3/4)x=(15/24)x------> (5/8)x
the answer is
5/8</span>
Answer:
Step-by-step explanation:
y = (x − 4) (x − 2)
Use the distributive property to multiply x−4 by x−2 and combine like terms.
y = x
^2 − 6x + 8
X would be: 0.5, 1.5, 4.5
Y would be: 3, 9, 27
When you divide 3 by 0.5 you get six so I basically just did trial and error with all the number
