Answer: For lines to be parallel, the slope has to be the same.

For lines to be perpendicular, the slope has to be the negative reciprocal.  4 x + 2 y = 7

2 y = − 4 x + 7

y = − 2 x + 7 /2

Compared to : y = 2 x − 3

Step-by-step explanation: Just a good guess.

Answer:

 -5 when ...

Step-by-step explanation:

The rules of exponents can help you simplify the given product.

<h3>Rules</h3>

  (a/b)^c = (a^c)/(b^c)

  (ab)^c = (a^c)(b^c)

  (a^b)(a^c) = a^(b+c)

  (a^b)/(a^c) = a^(b-c)

<h3>Application</h3>

  \left(\dfrac{x}{y}\right)^2(-x^2y)^3=\\\\\dfrac{x^2(-1)^3(x^2)^3y^3}{y^2}=-x^{2+2\cdot3}y^{3-2}=-x^8y

This expression does not match any of those offered.

When x=-1 and y=5, this becomes ...

  -(-1)^8(5)=\boxed{-5}

We’re told that QR and RS are equal, so this is an isosceles triangle.

Meaning the two base angles must also be equal

Using this information, we know that the third angle must be 180 - (22 + 22), since the angles in a triangle add up to 180
