How many solutions does this linear system have y= 1/2x+4 x+2y=-8

Mathematics
1 answer:
lara [203]3 years ago
4 0

Answer:

1 solution

Step-by-step explanation:

y = 1/2x + 4  

x + 2y = -8

Solve the second equation for y.

2y = -x - 8

y = -1/2x - 4

The two equations in slope-intercept form are:

y = 1/2x + 4

y = -1/2x - 4

The system consists of two lines with different slopes, so they intercept at a single point which is the solution.

Answer: 1 solution

N bisects MO. MN = 7x - 15, NO = 2x + 5. Find x
mrs_skeptik [129]

Answer:

x = 4

Step-by-step explanation:

I don't see a picture, so I'm assuming that M, N, O are points on a line segment with endpoints M and O.

Point N bisects segment MO, so it's in the middle of that segment.  That means the distance from M to N and the distance from N to O are equal.

7x - 15 = 2x + 5

5x - 15 = 5

5x = 20

x = 4

A college football stadium has a capacity of 100,000 people. The team is sponsoring a family day when tickets are $50 per person
Keith_Richards [23]

Answer:

I believe the variable N would be 100,000 because it is saying that tickets are $50 a person so you have to multiply that by how many people are at the stadium. So you would do 50(100,000) which equals 5,000,000.

Step-by-step explanation:

Explanation is in the answer above.
