Answer:
x^2-5x+10
Step-by-step explanation:
As they are two zeros and the standard equation is
x^2+(alpha+beta)x+alpha*beta
Answer:
y= -5x - 21
Step-by-step explanation:
parallel lines have the same slope, so you know the slope.
you need to use the point slope formula y-y1=m(x-x1)
with this equation, this looks like y - -1 =- 5(x - -4)
double negatives are positives, so to keep this easier on the eyes, let's make it y + 1= -5(x + 4)
distribute the -5. you should get y + 1 = -5x - 20
subtract 1 to move it from the left side to the right and you get your answer!
y = -5x - 21
ANSWER

EXPLANATION
From the mnemonics SOH-CAH-TOA.
We want to find the cosine of y
CAH means cosine ratio involves adjacent over the hypotenuse.

From the right by triangle, the side ajacent to angle y is 64 units and the hypotenuse is 80 units.


In a dollar amount, it would round to 50 cents.
Distribute (2x+y) throughout (4x^2-2xy+y^2). You should get
8x^3-4x^2y+2xy^2+4x^2y-2xy^2+y^3
Simplify and collect like terms and you should get 8x^3+y^3
