Answer:

the marked question is "different." It is asking to solve for y, not x.
y = 4 -1/2x
x = 8 -2y

Step-by-step explanation:

a) All of the equations ask for a solution for x, except the marked one at lower left. It is the "different" question.

b) We can divide the upper right equation by 6 to find the solution for y.

24 -3x = 6y

4 -1/2x = y

y = 4 - 1/2x

c) We can divide the lower-right equation by 3 to find the solution for x.

24 -6y = 3x

8 -2y = x

x = 8 -2y

Answer:

(7y + 3x)(7y - 3x)

Step-by-step explanation:

a² - b² = (a + b)(a - b)

49y² - 9x² = (7y)² - (3x)² {a = 7y ; b - 3x}

= (7y + 3x)(7y - 3x)

I’m confused on this one

dedylja [7]

It's a parallelogram so if one angle is 90 degrees they all will be because of transverse angles and all that good stuff.

So we're given the diagonal of a rectangle and one side and we're asked to find the other. The diagonal of a rectangle is the hypotenuse of the right triangle whose legs are the sides of the rectangle. So this is a Pythagorean Theorem question in disguise:

$AB^2 + AD^2 = BD^2$
