Which system of equations can be used to solve for the point of intersection of the lines on the graph? A) y = x - 7; y = 2x + 2
ratelena [41]

Answer:

C) y = 2x + 7; y = 2x + 2

Step-by-step explanation:

The two lines are parallel and so will have the same slope.

From the graph, the slope of both lines are two.

Using slope intercept formula, y=mx+c, with m=2, we have y=2x+c

The blue line has a y-intercept of 2 so the equation is

y = 2x + 2

The red line has a y-intercept of -7 so the equation is

y = 2x - 7

Hence the system is

y=2x+2

y=2x-7

The correct answer is C

5. The length of a rectangular swimming pool is 50 yards, and the width of the pool is 16
d1i1m1o1n [39]
The answer is C. I got this by doing a^2 + b^2= c^2. 50^2 + 16^2=c^2, 2500 + 256 = c^2, 2756 = c^2, then you take the square root of 2756 and that gives you your answer 52.50 yards. Hope this helps :D

A test asked students to find the ratio of circles to triangles.Greg got 5:2 as his answer and Paige got 2:5.Do there answers me
adoni [48]

Answer:

No.

Step-by-step explanation:

This is because 5:2 could mean there are 5 circles to 2 triangles and 2:5 could mean 2 circles to 5 triangles.

5 circles is not the same as 2 circles as 2 triangles is not the same as 5 triangles.
