Question

Two lines, A and B, are represented by the following equations:

Line A: 4x + 4y = 16
Line B: x + y = 4

Which statement is true about the solution to the set of equations?
It is (1, 2). There are infinitely many solutions. It is (1, 5). There is no solution.

Answer 1

what happens when you divide every term in line A by 4...?

Answer 2

Infinite

Answer 3

Consider the following set of equations:

Equation R: −3y = −3x – 9
Equation S: y = x + 3

Which of the following best describes the solution to the given set of equations?
No solution One solution Infinite solutions Two solutions

Answer 4

because they are the same

Answer 5

Infinite

Answer 6

Because they are the same

Answer 7

Consider the following equations:

−x − y = 1
y = x + 3

If the two equations are graphed, at what point do the lines representing the two equations intersect?
(−1, 2) (−2, 1) (1, −2) (2, −1)

Answer 8

Just plug in the values and see which one works

Answer 9

SO (-1,2) ,(-2,1)

Answer 10

I don't know I don't get the concept

Answer 11

I ts just substituting in values

Answer 12

1,-2

Answer 13

When you substitue in that value do both side equal the same.

Answer 14

-1,2

Answer 15

try to plu that in y=x+3

Answer 16

ya -1,2 works

Answer 17

Consider the following set of equations:

Equation A: y = 2x + 4
Equation B: y = 3x + 1

Which of the following is a step that can be used to find the solution to the set of equations?
2x + 4 = 3x + 1 2x = 3x + 4 2x + 4 = 3x 2x + 1 = 3x + 4

Answer 18

I got 2x+4=3x+1

Answer 19

ya

Answer 20

is that right

Answer 21

ya

Answer 22

Consider the following system of equations:

y = −x + 2
y = 3x + 1

Which description best describes the solution to the system of equations?
Line y = −x + 2 intersects line y = 3x + 1. Lines y = −x + 2 and y = 3x + 1 intersect the x-axis. Lines y = −x + 2 and y = 3x + 1 intersect the y-axis. Line y = −x + 2 intersects the origin.

Answer 23

Lines y = −x + 2 and y = 3x + 1 intersect the y-axis this is what I got

Answer 24

I got none of those

Answer 25

what did you get

Answer 26

I got at (.25,1.75)

Answer 27

Consider the following pair of equations:

y = x + 4
y = −2x − 2

Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.

Answer 34

are you

Answer 35

16

Answer 36

oh

Answer 37

either way Anser is (-2,2)

Answer 38

I need to show my work how to get tnswer

Answer 39

OK

Answer 40

1.Substitute
-2x-2=x+4
2. Solve for x.
-2x-2=x+4
+2x +2x

-2=3x+4
-4 -4

-6= 3x
/3 /3

-2=x
3. Now find the y value by substituting in the x value

Answer 41

cool pic

Answer 42

2=(-2)+4
so (-2,2)
