Step by step explanation: I'm Sorry this answer is late but here! I don't really get number 2 I'm sorry.

question 1

x=-y

2x-y=-6

x=-y

2(-y)-y=-6

x=-y

y=2

x=-(2

y=2

(-2,2)

x=-2,

y=2

Question 2

-2x + 6y = 30

-2x + 6y + -6y = 30 + -6y

-2x + 0 = 30 + -6y

-2x = 30 + -6y

x = -15 + 3y

x = -15 + 3y

Aaron and noah wanted to have a contest to see which of their paper airplanes could fly the longest distance. Aaron's plane flew
Marina CMI [18]

Aaron's plane flew 3.21 meters further than Noah's plane.

<u><em>Explanation</em></u>

Aaron's plane flew 4 meters and Noah's plane flew 79 centimeters.

So, first we need to <u>convert 79 centimeters into meters</u>.

We know that, 1 centimeter = 0.01 meter

So, 79 centimeters = (0.01*79)meter= 0.79 meter

Now, the difference of distance between Aaron's plane and Noah's plane is (4-0.79) meters = 3.21 meters

What are the zeros of f(x)=x^2+x-20?
zzz [600]
F(x) = x² + x - 20 = x² + 5x - 4x - 20 = x(x + 5) - 4(x + 5) = (x + 5)(x - 4)

f(x) = 0 ⇔ (x + 5)(x - 4) = 0 ⇔ x + 5 = 0 or x - 4 = 0 ⇒ x = -5 or x = 4

Answer: C. x = -5 and x = 4.
