Answer:
The function is even because f(x) = f(−x).
Step-by-step explanation:
we know that
An even function is one for which
f
(−x)=f(x) for all x in its domain.
An odd function is one for which
f(
−x)
=−f(x) for all x in its domain
In this problem we have
so
therefore
f
(x)=f(-x) for all x in its domain.
Is a even function
Answer: 40%
Step-by-step explanation:
To find the percent, divide the amount donated by the full amount of money raised. 400/1000 =<em> 0.4</em>.
Now to make this into a percentage, multiply the answer by 100. 0.4 * 100 = 40.
Answer:
If your quadratic equation it is in the form of x^2+bx+c=0 (in other words, if the coefficient of the x^2 term=1), it's possible (but not guaranteed) that a relatively simple shortcut can be used to factor an equation. Find two numbers that both multiply to make C and add to make B.

Step-by-step explanation:
For the triangles to be congruent.
The hypotenuse and a leg of the triangle on the left and the hypotenuse and a leg of the triangle on the right must be congruent, thus
4y = x + 4 → (1)
x = y + 8 → (2)
Substitute x = y + 8 into (1)
4y = y + 8 + 4 = y + 12 ( subtract y from both sides )
3y = 12 ( divide both sides by 3 ) )
y = 4
Substitute y = 4 into (2)
x = 4 + 8 = 12
Thus
x = 12 and y = 4
