2p+3q=-7 <br> 3p+5q=-12<br> What is the solution in an ordered pair?
natita [175]

Answer:

(p, q ) = (1, - 3 )

Step-by-step explanation:

2p + 3q = - 7 → (1)

3p + 5q = - 12 → (2)

Multiplying (1) by 3 and (2) by - 2 and adding the result will eliminate p

6p + 9q = - 21 → (3)

- 6p - 10q = 24 → (4)

Add (3) and (4) term by term to eliminate p

0 - q = 3

-q = 3 ( multiply both sides by - 1 )

q = - 3

Substitute q = - 3 into either of the 2 equations and solve for p

Substituting into (1)

2p + 3(- 3) = - 7

2p - 9 = - 7 ( add 9 to both sides )

2p = 2 ( divide both sides by 2 )

p = 1

Identify the domain and range for the table from problem #5 of your assignment. Also, determine if it represents a function.
Lana71 [14]

Answer:

Domain: {4,5,7,10}

Range: {2,4,8}

Not a function

Step-by-step explanation:

The domain is all the x-values.

The range is all the y-values.

However, this isn't a function because two different inputs have the same output. If it were a function, there would be one unique output for every input.

Rearrange the equations and identify the equations parallel lines

a) \\&#10;y=2x-5 \\ \\&#10;b) \\&#10;3y=2x+4 \\&#10;y=\frac{2}{3}x+\frac{4}{3} \\ \\&#10;c) \\&#10;2y=4x-5 \\&#10;y=2x-\frac{5}{2} \\ \\&#10;d) \\&#10;3y=x+4 \\&#10;y=\frac{1}{3}x+\frac{4}{3} \\ \\ &#10;e) \\&#10;5-3y+x=0 \\&#10;-3y=-x-5 \\&#10;y=\frac{1}{3}x+\frac{5}{3} \\ \\&#10;f) \\&#10;6y-4x-5=0 \\&#10;6y=4x+5 \\&#10;y=\frac{4}{6}x+\frac{5}{6} \\&#10;y=\frac{2}{3}x+\frac{5}{6}

Parallel lines have the same slope, and in the y=mx+b form "m" is the slope.
B and F are parallel.
A and C are parallel.
D and E are parallel.
