Based on the graph, which statement is correct about the solution to the system of equations for lines A and B? (1 point)

(3, 4) is the solution to both lines A and B.

(3, 4) is the solution to line A but not to line B.

(0, 2) is the solution to both lines A and B.

(0, 2) is the solution to line A but not to line B.

Answer 2

An unknown number y is 20 more than an unknown number x. The number y is also x less than 2. The equations to find x and y are shown below:

y = x + 20
y = –x + 2

Which is a correct step to find x and y? (1 point)


Multiply the equations to eliminate y.

Add the equations to eliminate x.

Write the points where the graphs of the equations intersect the x-axis.

Write the points where the graphs of the equations intersect the y-axis.

Answer 3

(08.06 LC)
Variable g is 8 more than variable w. Variable g is also 4 less than w. Which pair of equations best models the relationship between g and w? (1 point)


g= w – 8
g = w + 4

w = 8g
w = g – 4

g= w + 8
g = w – 4

w = 8g
w = g + 4

Answer 4

Answer 8

for the first question, since the 2 lines are intersecting, there can only be 1 solution, it's pretty obvious

Answer 9

1 solution for both lines*
