Answer:

−6x+12

Step-by-step explanation:

Expand by distributing terms.

-6x-6\times -2

−6x−6×−2

2 Simplify  6\times -26×−2  to  -12−12.

-6x-(-12)

−6x−(−12)

3 Remove parentheses.

-6x+12

−6x+12

Answer:

50 years.

Step-by-step explanation:

Hope this helps!

Step-by-step explanation:

We find the stationary point of (20 + 2x)(1200 - 60x),

where x is the unit rate of increase/decrease.

d/dx [(20 + 2x)(1200 - 60x)]

= d/dx (-120x² + 1200x + 24000)

= -240x + 1200.

When d/dx [(20 + 2x)(1200 - 60x)] = 0,

We have -240x + 1200 = 0. => x = 5.

Price per shirt that maximise revenue

= $20 + $2x = $20 + $2(5) = $30.

Maximum revenue

= (20 + 2(5))(1200 - 60(5))

= $30 * 900 = $27,000.

Answer:

domain: -2,-3, -1, 0, 1, 2

range: -2, -1, 0, 1, 2, 3

domain is the x value, range is for the y values

in this case, this isn't a line, it's just a line plot, so you just list the coordinates of where each point is for x and y.

Answer:

red: 13/33

yellow: 12/33

blue: 8/33

Step-by-step explanation:

Add together all of the values to find the total amount of sections (13+12+8=33) --> this will be your denominator

From there, each time you make the numerator the number of that color, which gives you:

red: 13/33

yellow: 12/33

blue: 8/33

I hope this helps!

Answer:

The probability of landing on red is 13/33, the probability of landing on yellow is 12/33, and the probability of landing on blue is 8/33.

Step-by-step explanation:

Everything is just a fraction, so just add all the numbers for your denominator, and put the other number for red yellow or blue as the numerator then simplify the fraction

Answer: 7,8,9

Step-by-step explanation: all the numbers between 6 and 10

Answer:

10%

Step-by-step explanation:

10+90= 100 students total

10 is 10% of 100

Answer: The correct answer is 40 I got this question right.

Answer:

25

Step-by-step explanation:

if you look at it, 250 is 1/4 of 1000 and 100 is 1/10 of 1000 so divide 250 by 10 and you get your answer.

The equation y--4=-2(x--1)

Answer:\

Step-by-step explanation:

Answer:

$216

Step-by-step explanation

We know that we are paying 80% of the price of the airpods (20% off) so we can multiply the full price by 0.8.

250 * 0.8

This will give us 200.

Now, we need to add the sales tax which is 8%.

Simply multiply the 200 by 1.08 since we are paying the 200$ plus an extra 8% of the cost.

200 * 1.08 = $216

I hope this helped.

Answer:

y = 6

Step-by-step explanation:

You solve by using the pythagorean theorem, which is:

[tex]a^{2} +b^{2} =c^{2}[/tex]

Where a and b are legs of the triangle, and c is the hypotenuse, or y in this case. So let's rearrange this equation for c:

[tex]c=\sqrt{a^{2} +b^{2} }[/tex]

Now, we can substitute in the known values and solve:

[tex]c=\sqrt{3.6^{2} +4.8^{2} } = \sqrt{36} = 6[/tex]

Therefore, the value of y is 6

Answer:

[tex] \boxed{y = - \frac{3}{4} x + 4}[/tex]

Step-by-step explanation:

The graph decreases. That meand the slope is in negative.

[tex]y = mx + b[/tex]

where m = slope and b = y-intercept. If the slope is positive, the graph will increase. Otherwise, decrease.

The only choice that the slope is negative is the third choice.

Answer:

2x +16

Step-by-step explanation:

group them by similar variables

8x-6x. 11+5

2x+16

Answer:

2x+16

Step-by-step explanation:

combine like terms

8x-6x+11+5

8x-6x=2x

2x+11+5

11+5=16

2x+16

Answer:

x = -7

Step-by-step explanation:

2x + 3 = 1x + -4

-1x        -1x

1x + 3 = -4

    -3      -3

x = -7

Step-by-step explanation:

I think this is it :

For the schones a) 16,16 is double 8 so whatever the ingredients double them!

So it will be: 400g flour

60g caster sugar.... And so on

B) 4 is half 8, so whatever the ingredients half them

Flour = 100g

Sugar = 15g..... And so on

C) 24 is three time 8, so all ingredients triple them

Flour= 600g

Sugar = 90g...and so on

D) 40 is five times 8 so all ingredients multiply by 5

Flour= 1,000 g

Sugar= 150g.... And so on

E) 80 is 10 times 8

So multiply by 10

Flour = 2,000g

Sugar = 300g... And so on

F) 2 is one by fourth of 8

So, flour = 50g

Sugar = 7.5g

For ice-cream:

A) 8 is double 4 so whatever ingredient double

Double cream= 600ml

Milk= 640ml and so on

B) 2 is half 4 so make ingredients half

Double cream = 150ml

Milk = 160ml

C) here because it's only one person

U will divide all the ingredients by 4

So double cream = 300/4 =75ml

Milk = 320/4 = 80ml

So on...

D) for 3 people we will use bit c

For 3 people = double cream= 75x3= 225

Milk = 80x3 = 240ml

And so on

E) so for(c), we found for one person now we can easily use that and find this

Now for 6 people

For person, as we saw, = 75ml

For 6 people double cream = 75x6= 450ml

And for milk for 1 person = 80ml

For 6 people = 80x6= 480ml

And so on

F) 10 people

Double cream = 75ml x 10 = 750ml

Milk = 80ml x 10 = 800ml

For fish pie,

A) 15 is three times 5 so we will multiply 5 to each ingredient

Cod= 1500g

Haddock = 1200g and so one

B) for 1 person we will also divide each ingredient by 5 = Cod = 500÷5 = 100g

Haddock = 400÷5 = 80g and so one

C) we will use bit b for this too

Cod = 100 x 2 = 200g

Haddock = 80g x 2 = 160g and so on

D) 4 people

Cod= 100g x 4 = 400g

Haddock = 80 x 4 = 320g and so on

E) 8 people

Cod = 100 x 8 = 800g

Haddock = 80 x 8 = 640g and so on

F) 11 people

Cod = 100 x 11 = 1100g

Haddock = 80 x 11 = 880g

And so on

Answer:

Step-by-step explanation:

The diagonals of a rectangle are equal.

2x + 10 = 56         That minus sign can't be there. Subtract 10 from both sides.

2x  = 56 - 10         Combine

2x = 46                 Divide by 2

x = 46/2

x = 23

Answer:

Approximately $1.87 ($1.869)

Step-by-step explanation:

There are 2 ways to do it

1.78 x 1.05 = 1.869 / $1.87

Or

1.78 x .05 = .089

1.78 + .089 = 1.869 / $1.87

answer: x= 2,y=1
