Steps:

let “x” be number of hrs
let “y” be total cost

Abe:

50x + 75 = y

Plumbing Service:

65x=y

Since both equations are equal to y, you can set them equal to each other.

65x = 50x + 75

isolate for x:

65x - 50x = 75
15x = 75
x = 5

therefore it will take 5 hours for each to cost the same. you should call Abe for any task more than 5 hours because it will be cheaper and you should call the Plumbing Service for any task less than 5 hours because it will be cheaper.

Parabola Skate Rental rents skate boards for $4.50 per hour with a rental fee of $35. Arc of Hawk Skate Rental rents skate board
NNADVOKAT [17]

Answer: \bold{13\dfrac{1}{3}\ \text{hours}}

<u>Step-by-step explanation:</u>

Parabola Skate Rental:   4.50x + 35

Arc Hawk Skate Rental:  5.25x + 25


If you want to know when their cost will be the same, set the equations equal to each other.

5.25x + 25 = 4.50x + 35

0.75x + 25 = 35          <em>subtracted 4.50x from both sides</em>

0.75x = 10           <em>subtracted 25 from both sides</em>          

     x=\dfrac{1000}{75}        <em>divided both sides by 0.75</em>

     x = 13\dfrac{1}{3}        <em>simplified the fraction</em>

Barbara is tiling her craft room floor with square tiles. She wants 6/10 of squares tiles to be red. If she uses 18 red tiles, h
Sveta_85 [38]

Answer:

6 and 18 are common because 6x3=18. Remember the rule to multiply all numbers by 3. So multiply 10 by 3 and you will get 30. The total number of square tiles needed is 30 tiles. If you are putting it into a ratio it would be 18:30.

In which diagram are angles 1 and 2 vertical angles?
Solnce55 [7]

<u>Answer</u>

First diagram shows  1 and 2 vertical angles

<u>Explanation</u>

From the all four diagrams,we get the diagram first shows the vertically opposite angles.  

angle 1 and angle 2 are vertically opposite angles

vertically opposite angles are equal in measurements. when two lines are intersect each other form four angles, out of this four angles two pairs of vertically opposite  angles are there.

All other figures  angle 1 and 2 shows adjacent angles.

O find the minimum value of the quadratic expression −4x2+8x−25,
fredd [130]

Answer:

Marla didn't use the right steps to complete the square. Maria made a mistake in step 1, she put 8x instead of -2x

Step-by-step explanation:

we have

-4x^{2}+8x-25

This is a vertical parabola open downward

The vertex is a maximum

Find the vertex

step 1

Factor the leading coefficient -4

-4(x^{2}-2x)-25

step 2

Complete the square

-4(x^{2}-2x+1-1)-25

step 3

-4(x^{2}-2x+1)-25+4

-4(x^{2}-2x+1)-21

step 4

Rewrite as perfect squares

-4(x-1)^{2}-21

the vertex is the point (1,-21)

so

The maximum value of the quadratic equation is (1,-21)

therefore

Marla didn't use the right steps to complete the square. Maria made a mistake in step 1, she put 8x instead of -2x
