Question

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

Line A: x + y = 6
Line B: x + y = 4

Which statement is true about the solution to the set of equations?
There are infinitely many solutions. There is no solution. It is (6, 4). It is (4, 6).

Answer 1

Start by eliminstion which I think will be easier

Answer 2

I think its no solution

Answer 3

*elimination

Answer 4

Yes you are right they are parrallel lines

Answer 5

The distances (y), in miles, of two cars from their starting points at certain times (x), in hours, are shown by the equations below:

Car A
y = 55x + 32

Car B
y = 42x + 58

After how many hours will the two cars be at the same distance from their starting point and what will that distance be?
2 hours, 142 miles 2 hours, 145 miles 3 hours, 142 miles 3 hours, 145 miles

Answer 6

since both equations are in the form y = ____, we can set them equal to each other

55x + 32 = 42x + 58

solve for x

Answer 7

I think it's 2,142

Answer 8

right

Answer 9

Variable p is 2 more than variable d. Variable p is also 1 less than variable d. Which pair of equations best models the relationship between p and d?
p = d + 2
p = d − 1 p = d − 2
p = d + 1 d = 2p
d = 2p − 1 d = 2p
d = 2p + 1

Answer 10

I think its the first one

Answer 11

right

Answer 12

A set of equations is given below:

Equation A: e = 4f + 1
Equation B: e = 3f + 5

Which of the following is a step that can be used to find the solution to the set of equations?
4f + 1= 3f 4f = 3f + 5 4f + 5 = 3f + 1 4f + 1 = 3f + 5


I hope your right because this is a final exam
