Replace values of n in expression with 1/4.

9(1/4 + 2) - 5(1/4)

Distributive property

9/4 + 2 - 5/4

Rearrange.

2 + 9/4 - 5/4

Subtract.

2 + 4/4

Simplify.

2 + 1

<h3>The expression is equal to 3 when n = 1/4. </h3>

A system of equations has infinitely many solutions. If 2y – 4x = 6 is one of the equations, which could be the other equation?

Molodets [167]

Hi there!

$\large\boxed{y = 2x + 6}$

For a system to have infinite solutions, the lines have to be the same. We can begin by rearranging the given equation into the format y = mx + b:

2y - 4x = 6

Move x to the opposite side:

2y = 4x + 6

Divide all terms by 2:

y = 2x + 6

The answer choice that matches this is the first one.

Write and equation for (-1,2) and (0,0)

Natali5045456 [20]

Since the slope is -2 because
x1: -1 x2: 0
y1: 2 y2: 0
y2-y1/x2-x1 = slope (0-2/0+1= -2/1 = -2)

You would havr to change it into point slope form so it would look like this
Y-2 = -2(x+1)
y-2 = -2x -2
+2 +2
y = -2x + 0
Hope this helps:)
