Solution


a.) y = 15x - 50
when x = 7


b.) y = 1/2x + 20
when x = 50


c.) y = (3x)2 - 36
when x = 3


d.) y = 2.5x + 3.8
when x = 0.66

Answers

Answer:

a) y = 55

b) y = 45

c) y = -18

d) y = 5.45

Step-by-step explanation:

y = 15x - 50    when x = 7

y = 15(7) - 50

y = 105 - 50

y = 55

y = 1/2x + 20   when x = 50

y = 1/2(50) + 20

y = 25 + 20

y = 45

y = (3x)2 - 36    when x = 3

y = (3(3))(2) - 36

y = 9(2) - 36

y = 18 - 36

y = -18

y = 2.5x + 3.8    when x = 0.66

y = 2.5(0.66) + 3.8

y = 1.65 + 3.8

y = 5.45

The break-even point occurs when the amount of money they receive from selling popcorn is
equal to the amount of money they spent to make the popcorn. It is when Revenue-Total Cost.
The break-even point tells how many items they must create and sell in order to recover their

Lupita rides a taxi that charges a flat rate of $6. 75 plus $3. 20 per mile. If the taxi charges Lupita $40. 03 in total for her trip, how many miles is her ride?


Enter your answer in the box as a decimal to the nearest tenth of a mile.

_____ miles

Answers

Answer:

10.4 miles

Step-by-step explanation:

Write an equation for the total cost paid as a function of the # of miles driven:

L(x) = $6.75 + ($3.20/mile)x

and set this equal to $40.03 to determine the # of miles Lupita rode:

L(x) = $6.75 + ($3.20/mile)x = $40.03

Isolate the x term by subtracting $6.75 from both sides:

($3.20/mile)x = $40.03 - $6.75 = $33.28

Finally, divide both sides by  ($3.20/mile):

x = $33.28 /  ($3.20/mile)

 =  10.4 miles

Lupita rode 10.4 miles in the taxi.

10.4
Because you do 40.03- 6.7 then divide the answer by 3.2

Answer:

a) 3/2 or 1 1/2

b) 5/3 or 1 2/3

Step-by-step explanation:

1/2 + 1/2 + 1/2 =

3 x 1/2 =

3/2 or 1 1/2

1/3 + 1/3 + 1/3 + 1/3 + 1/3 =

5 x 1/3 =

5/3 or 1 2/3

Answer: (a) 1 1/2 and (b)  1 2/3

Step-by-step explanation:  (a) 1/2 + 1/2 + 1/2 = 1/2 x 3

                                                                     = 3/2
Now convert this into mixed fractions (basically divide the smaller number of the improper fraction by the the bigger one).

                                            Therefore, 3/2 = 1 1/2 ( 1 1/2 is 1 whole and 1/2)

(b) 1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 = 1/3 x 5
                                                     = 5/3

mixed number = 1 2/3 ( 1 2/3 is 1 whole and 2/3)

From midnight to 2:00 am, the temperature rose
1.55
1.55°C each hour. If the temperature at midnight was
−
7
−7°C, what was the temperature at 2:00 am?

Answers

Answer:

-3.90

Step-by-step explanation:

1) 1.55+1.55 =3.10

2) -7+3.10= (-3.90)

The answer is -3.9 degrees Celsius because 1.55+1.55=3.10 (We do this because 1h= +1.55 so 2h = +3.10) and then we do -7+3.10= 3.90 degrees Celsius (we do this because we do the initial temperature plus the temperature risen in 2 hours)

The triangle shown on the coordinate grid is translated 6 units to the right and 3 units down.
Which would be the measure of an angle of the resulting triangle?
(ignore the answer i choose lol) but pls help me

Answers

Answer:

75°

Step-by-step explanation:

Even if a triangle is translated, the original shape stays the same.

So, to get the answer, first add the first two angles of the triangle:

60 + 45 = 105

Then, subtract from 180, because 180 is equaled to all the angles added up on any triangle:

180 - 105 = 75.

So, you get 75°.
