Y = x^2 +2x
y = 3x +20
so:
x^2 + 2x = 3x + 20
subtract 3x from both side:
x^2 +2x -3x = 20
combine like terms:
x^2 -x = 20
subtract 20 from each side:
x^2 -x -20 = 0
factor the polynomial:
(x-5) (x+4) = 0
solve for x
x = 5 and x = -4 ( 5-5 = 0 and -4 +4 = 0 )
replace x = 5 in 2nd equation: y = 3(5) +20
y = 15 +20
y = 35
replace x with -4 in same equation:
y = 3(-4) +20
y = -12 +20
y = 8
so solution is (5,35) and (-4,8)
The measure of angle U will be equal to the measure of angle W.
Because W is pronounced "double u", W = 2 * U.
Therefore U = W and U = 2 * W, so both U and W = 0.
Just kidding.
The correct answer is the smallest prime number greater than 40.
Answer:
2af+bf = 2af+bf
Step-by-step explanation
f(x) = 4x2 – 3x. = x(4x−3)
Answer:
measure of angle YVZ=56°
Step-by-step explanation:
angle WVY and angle YVZ form a right angle, meaning they add to 90 degrees.
We can make an equation out of this:
2x+3x+5=90
solve for x
5x+5=90
5x=85
x=17
substitute x back into the expression for angle YVZ because that's the measure we're looking for
angle YVZ=3(17)+5=56
