Identify the vertex for the given function. 2(x-1)^2 + 8

Answer:

A

Step-by-step explanation:

Answer:

-7.5

Step-by-step explanation:

Whole numbers are natural numbers from 0 to infinity. This does not include decimals or fractions. For example, these numbers are 0, 1, 2, 3, 4...

Integers are whole numbers, but they include negative numbers. So, from negative infinity to positive infinity. This does not include decimals or fractions. For example, these numbers are ... -3, -2, -1, 0, 1, 2, 3 ...

A rational number is any number that can be expressed as a fraction. So, this includes -7.5, as -7.5 can be expressed as -[tex]\frac{15}{2}[/tex].

Therefore the answer is -7.5.

Part A: Create an equation that shows the amount of money earned, E, for working x hours in a week when there is no overtime. (3 points)

x hours in a week and there is no overtime and x <= 35 so equation:

E(x) = 16x

Part B: Create an equation that shows the amount of wages earned, T, for working y hours of overtime. Hint: Remember to include in the equation the amount earned from working 35 hours. (3 points)

Regular hours = E(x) = $16 x 35 = $560

T(y) = 21y + 560

Part C: Marco earned $602 in 1 week. How many hours (regular plus overtime) did he work? Show your work. (4 points)

21y + 560 = 602

21y = 42

y = 2

Marco worked 37 hours (35 regular plus 2 hours overtime)

Answer:

6

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

Since there are two white bars (which equals 4 each) it equals 8.

There are 2 shaded blocks (which equals -2 each) and that amounts to -2.

8 - 2 = 6

Answer:

the first one is (6.5,13)

the second one is (4,4)

Step-by-step explanation:

-2x-0=-13    

-2x=-13 divide -2 by -13

x=6.5

-2(0)-1y=-13

0-1y=-13

-1y=-13

13

so that gives you (6.5,13)

2x+2(0)=8

2x+0=8

2x=8 divide two by eight

x=4

2(0)+2y=8

0+2y=8

2y=8 divide two by eight

y=8

Answer:

{the question is asking to find the value of x not m}

The value of x is 9°

Step-by-step explanation:

8x-2°+47° = 12x+9°{an exterior angle formed by producing the side of triangle is equal to two non adjacent angle}

or, 8x+45° = 12x+9°

or, 8x-12x = 9°-45°

or, -4x = -36°

or, x = -36°/-4

or, x = 9°

Answer:

The answer is 77 degrees

Answer:

x=-3. y=-5

Step-by-step explanation:

Equating both equations,

6x + 13 = 2x + 1

6x - 2x = 1 - 13

4x = -12

x = -3

Plug in the value of x in the given first equation,

y = 6* (-3) + 13 = -18 + 13 = -5

Answer:

{y,x} = {-5,-3}

Step-by-step explanation:

System of Linear Equations entered

y - 6x = 13

 y - 2x = 1

Graphic Representation of the Equations

-6x + y = 13        -2x + y = 1  (attached)

Solve by Substitution

y = 2x + 1

(2x+1) - 6x = 13

   - 4x = 12

4x = - 12

    x = - 3

  y = 2x+1

   x = -3

 y = 2(-3)+1 = -5 (final answer)

hope it helps you!

Answer:

2

Step-by-step explanation:

Two negatives makes a positive, - (-6) can be rewritten as +6 or simply just 6.

Proceed to do simple calculations, 6 - 4 = 2.

Answer:

2

Step-by-step explanation:

Multiply the -6 by -, and it equals a positive 6 (When you multiply a negative number by a negative number it becomes a positive).

Finish the equation by subtracting 6 - 4 = 2

I know it might not make sense but trust me, I had to do problems like this.

Hope this helps!

Answer:

c = 9

Step-by-step explanation:

2c - 5 = c + 4

Subtract c from both sides

c - 5 = 4

add 5 to both sides

c = 9

Answer:

y=7x/4-3

Step-by-step explanation:

We can use the formula y=mx+b. m=slope so y=7/4x+b. We know that the line intersects the point (0,-3) so we plug it in, x=0 and y=-3. -3=(7/4)*0+b. b=-3. Therefore, the equation is y=7x/4-3.

Answer: 60%

Step-by-step explanation:

Given: Climbing rate at the end of week 1 = 25 steps per minute.

Climbing rate at the end of week 4 =   60 steps per minute

The  percent increase in Maggie's rate of climbing steps from the end of week 1 to the end of week 4 will be :

[tex]\dfrac{\text{Climbing rate after week 4 - Climbing rate after of week 1}}{\text{Climbing rate after week 1}}\times100[/tex]

[tex]=\dfrac{40-25}{25}\times100\\\\=\dfrac{15}{25}\times100=15\times4=60\%[/tex]

Hence, the percent increase in Maggie's rate of climbing steps from the end of week 1 to the end of week 4 = 60%

Answer:

D. b = r+z

Step-by-step explanation:

Given the expression b-r = z, we are to solve for b. To do this, we will add 'r' to both sides of the equation as shown;

b-r+r = z+r

Since -r+r = 0, substitute:

b+0 = z+r

b = z+r

Hence the resulting equation when r is added to both sides of the equation is b = z+r

Hence option D is correct

Answer:

$63.55

Step-by-step explanation:

Taxes are charges paid by individuals and enforced by the government in other to fund government spending and various public expenditures.

The flowers cost $59.95 and tax is 6%.

Tax = 6% of flower cost = 0.06 × $59.95 = $3.6

The  total cost of the flowers is the sum of tax and the cost of flowers, hence:

Total cost of the flowers = $59.95 + $3.6

Total cost of the flowers = $63.55

Answer: $37.20

Step-by-step explanation:

24.50+12.70=37.20

Quinn earned a total amount of $37.20 which is the addition of the earnings from dog-sitting and the recycling cans.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

We have been given that Quinn earned $24.50 for dog-sitting and $12.70 for recycling cans.

We have to determine the total amount he earned.

The total amount is the addition of the earnings from dog-sitting and the recycling cans.

The total amount = earnings from dog-sitting + earnings from the recycling cans.

The total amount = $24.50 + $12.70

The total amount = $37.20

Therefore, he earned a total amount of $37.20.

Answer:

He can fit 2 more DVD's on the shelf.

And he'll have about 12 mm of extra space left.

Step-by-step explanation:

40×1.4 = 56cm  This is the length of space the 40 DVD's will take up.

60-56 = 4cm  This is the amount of space left.

4/1.4 = 2.857   the number of DVD's that will fit.

Of course, the decimal represents a partial DVD which is worthless.

Just to be sure, 2×1.4 = 2.8cm OK. But  3×1.4=  4.2cm which is 2mm too much

Slope = -1

Step-by-step explanation:

[tex](3, -5 ) = (x_1,y_1) \\ (-7,5)=(x_2,y_2)[/tex]

[tex]Slope = \frac{y_2-y_1}{x_2-x_1} [/tex]

Substitute values into the given equation

[tex]slope \: = \frac{5 - ( - 5)}{ - 7 - 3} \\ \\ slope \: = \frac{5 + 5}{ - 7 - 3} \\ \\ [/tex]

[tex]slope \: = \frac{10}{ - 10} \\ slope \: = - 1[/tex]
