PLEASE ANSWER! I WILL GIVE 80+ POINTS, BRAINLIEST, A THANKS, 5 STARS, AND A FOLLOW IF YOU ANSWER ALL OF THESE (P.S they all have to do with direct variation):

#1) If y varies directly with x, write an equation for the direct variation. Then find each value. If y = –4 when x = 10, find y when x = 5

#2) If y varies directly with x, write an equation for the direct variation. Then find each value. If y = 12 when x = –15, find y when x = 2

#3) If y varies directly with x, write an equation for the direct variation. Then find each value. Find x when y = 18, if y = 9 when x = 8.

The table below shows field goal statistics for three different kickers. Order the kickers by their field goal success rate from least to greatest. I have added a picture of the graph.

Answers

Answer:

Kicker C, kicker B, and then kicker A

Step-by-step explanation:

Just divide the field goals made by field goals attempted to get the success rate. A = 12 / 14 = 0.857      B = 15 / 18 = 0.83      C = 19 / 24 = 0.79

0.79 < 0.83 < 0.857

Acute triangle ABC is rotated about a point and then dilated by a scale factor of 1/2 to produce A'B'C'. What statement correctly compared triangle A'B'C' to triangle ABC?

The angle measures and side lengths of triangle A’B’C’ are half the size of those of triangle ABC

The angle measures of triangle A’B’C’ are the same as those of triangle ABC, but the side lengths of A’B’C’ are half the size of those of triangle ABC

The angle measures of A’B’C’ are the same as those of triangle ABC, but the lengths of A’B’C’ are twice the size of those of ABC

OR

The angle measures of A’B’C’ depend on the angle of rotation, but the side lengths of A’B’C are half the size of those of ABC

Answers

9 = 4 + x - 4x minus 4
5 = x - 4x
5 = -3x divide by -3
-3/5 = x
To solve this we know that 2+7=9 so for 4+1(x)-x4 to equal 9 you would first multiply x and 4 to get 4x. Next you would subtract 1x-4x which equals -3x+4 . What you do to the right you do to the left so 9-4=5. Which you the have 5=(-3x) so you then divide the 3x by 3 which leaves you with x. So x = -5/3 .

An image point of a tranformation has coordinates Y'(2, -4). If the pre-image point had coordinates Y(6, -12) what was the transformation and scale factor?
a. reflection with scale factor 3
b. reflection with scale factor 1/3
c. dilation with scale factor 3
d. dilation with scale factor 1/3

Answers

dilation with a scale factor 1/3. the original points are three times as big as the transformed points, so the transformation needed to reduce the size by three times smaller.

If a car is moving 50 mi/hr and travels 30 miles, how long did the journey take?

Answers

Answer:

36 minutes

Step-by-step explanation:

1 hour = 60 minutes

[tex]\frac{50}{60} = \frac{30}{m}[/tex]

50m = 1800

m = 36 minutes

The Journey will take 6 hours.

What is speed distance formula?Speed = Distance/Time Distance = Speed X TimeTime = Distance / Speed.

Given:

speed = 5 mph

Distance = 30 miles

So, speed = Distance / time

5 = 30 / time

time = 30/5

time = 6 hour.

Hence, the journey take 6 hour.

Today, everything at a store is on sale. The store offers a 20% discount.

a) The regular price of a T-shirt is $18. What is the discount price?

b) If the regular price of an item is dollars, what is the discount price in dollars? Write an expression.

c) The discount price of a hat is $18. What is the regular price?

Answers

Answer:

a. $14.4

b. $18 • .2 = $3.6

c. $21.6

Step-by-step explanation:

a. Make the 20% a decimal, and multiply by the regular price. Then, subtract that and you'll get the discounted price.

18 • .2 = 3.6

18-3.6 = $14.4

b. Use the equation multiplying the 20% as a fraction here.

c. Multiply $18 by .2 (the discount). Then, add that to the discount price ($18).

18 • .2 = 3.6

3.6 + 18 = $21.6
