Answer:

1) no, because a solution must be an ordered triple pair (x,y,z)

2) { x+y+z=5

{ 2x-3y+z=7

{ x+2y-4z=2

3) infinity many solutions

4) use equations (1) and (2) to eliminate y

5) solve one equation for one of its variables

Answer:

If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations. If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.

In the parallelogram, M

alexira [117]

Answer:

112°

Step-by-step explanation:

Given parallelogram JKLM with:

m∠KLO = 53°
m∠MLO = 59°

Find:

m∠KJM

We know opposite angles of parallelogram are congruent:

m∠KJM = m∠KLM

Use angle addition postulate:

m∠KLM = m∠KLO + m∠MLO
m∠KLM = 53° + 59°
m∠KLM = 112°

Write the equation of a line that is parallel to the following: 1. x = 5 2. y = -3

sineoko [7]

Answer:

1. x=6

2. y=2

Step-by-step explanation:

If x=5, the line is vertical, so we need a vertical line so that we are parallel. A vertical line is x= a constant

We can choose the value for x as long as it is not 5, that would make it the same line. I will choose x=6

If y=-3=5, the line is horizontal, so we need a horizontal line so that we are parallel. A horizontal line is y= constant

We can choose the value for y as long as it is not -3, that would make it the same line. I will choose y=2

What value makes the two expressions equivalent? 45x + 72y __(5x + 8y)

zimovet [89]

Answer:

Step-by-step explanation:

This is because of the distributive property.

The outside number is multiplied by each inside number.

So, if it's 9(5x+8y), then do 9*5x which is 45x and 9*8y which is 72y.
