Write an equation that is perpendicular to y= 1/2x+5 and passes through (4,8)

Mathematics
1 answer:
goblinko [34]3 years ago
4 0

Answer:

y = -2x + 16.

Step-by-step explanation:

The slope of the perpendicular line = -1 / slope of the given line

= -1 / 1/2 = -2.

Using the point slope form of the equation of a straight line:

y - y1 = m (x - x1)

y - 8 = -2(x - 4)

y - 8 = -2x + 8

y = -2x + 16  is the required equation.

Casey wants to buy a gym membership. One gym has a $150 joining fee and cost $35 per month. Another Jim has no joining fee and c
Katyanochek1 [597]

Answer:

After 6 months, Casey would pay $360 to join either gym.

Step-by-step explanation:

At the first gym, the cost is $35 per month in addition to a $150 joining fee.  So, the equation based on 'x' number of months and a total cost of 'c' is:

c = 35x + 150

At the second gym, the cost is just $60 per month.  So, the equation based on 'x' number of months and a total cost of 'c' is:

c = 60x

Since you want to find the number of months 'x' it would take until Casey would pay the same amount to be a member of either gym, you can take the two equations and set them equal to each other:

35x + 150 = 60x

Subtract 35x from both sides: 35x - 35x + 150 = 60x - 35x or 150 = 25x

Divide both sides by 25: 150/25 = 25x/25 or x = 6

So, after 6 months, the cost would be same.  The find the cost, replace 'x' with 6 in one of the equations:  c = 60(6) = $360.

AB, CD and EF are straight lines. <br> AB is parallel to CD.<br> work out the size of angle y.
Yuri [45]

Answer:

y = 108°

Step-by-step explanation:

Since, line AB is parallel to line CD,

By the definition of corresponding angles,

m∠FPB = m∠FQD

(2x + 16)° = (3x - 12)°

3x - 2x = 16 + 12

x = 28

(3x - 12) = 3(28) - 12

             = 72°

m∠FQD + m∠EQD = 180° [Linear pair of angles]

72° + y = 180°

y = 180 - 72

y = 108°

Which situation has a unit rate of 15 laps per hour?
trapecia [35]

Answer:

<em>Option C. Luigi runs 150 laps in 10 hours . </em>

Step-by-step explanation:

<u>Unit Rate</u>

We need to match for an option having a unit rate of 15 laps per hour.

To find the required rate, we divide the number of laps by the number of hours.

A. Luigi runs 44 laps in 4 hour . This gives a unit ratio of 44/4 = 11 laps/hour. This is not the correct option

B. Luigi runs 2 laps in 30 hours. This gives a unit ratio of 2/30 =0.07  laps/hour. This is not the correct option

C. Luigi runs 150 laps in 10 hours . This gives a unit ratio of 150/10 = 15 laps/hour. This is the correct option

D. Luigi runs 60 laps in 5 hours. This gives a unit ratio of 60/5 = 12 laps/hour. This is not the correct option

Option C. Luigi runs 150 laps in 10 hours .
