Which are the solutions of x2 = -5x + 8?

Answer: cups of cake mix: 19/24 cups of water: 11/64

Step-by-step explanation:

Because it is not dividing by a fraction all you have to do is multiply its denominator by 8.

42

Step-by-step explanation:

first we have to find out 40% of 30 which is 12 because 15 is 50% and 27 is 90% Wich would get us 12 with 40% percent then you would take 30 and add 12 which would lead you with 42

Answer:

[tex]\huge\boxed{\text{1. }\$ 15}[/tex]

[tex]\huge\boxed{\text{2. } \$ 1200}}[/tex]

Step-by-step explanation:

By examining the different parts of this equation and what they mean in the context of this problem, we can use the equation to find out different pieces of information about the scenario.

An equation in the form [tex]y = mx+b[/tex] is set up in the way that m = slope, and b = y-intercept.

When starting on a graph, you start at x = 0. Plugging 0 into the equation as x leaves y as 1200. This shows that the base price to make a book is

$1200.

Also, the equation shows that the slope of the line is 15. If we were to put this on to a graph, then every time x (books) increases by 1, y (cost) would increase by 15. Therefore, books cost $15 per book to publish. This makes it the total cost for every book published.

Hope this helped!

Answer:

just buy 2 slurpies and 20 candies

Step-by-step explanation:

its not rocket science

Answer:

The answer is D :)

Answer:

360 degrees around a point. the angle opposite 125 is vertically opposite so will be 125. 125 X 2 = 250

360 - 250 = 110. 110/2 = 55 degrees.

the angle opposite X is vertically opposite and is also an alternate angle to the angle of 55 degrees.

X = 55 degrees

Answer:

C and D

Answer:

The annual profit is $6384, if the baker sells 240cupcakes

Step-by-step explanation:

Annual profit in dollars from selling cupcakes = [tex]p(n)=41n-0.06n^2[/tex]

where n is the number of cupcakes sold .

We need to find the annual profit if the baker sells 240cupcakes.

If baker sells 240 cupcakes, so we have n = 240

Putting value of n in the given equation and finding profit

[tex]p(n)=41n-0.06n^2\\Put\:n=240\\p(240)=41(240)-0.06(240)^2\\p(240)=9840-0.06(57600)\\p(240)=9840-3456\\p(240)=6384[/tex]

So, The annual profit is $6384, if the baker sells 240cupcakes

[tex]6 - 7(x + 1) = - 3(2 - x)[/tex]

[tex]6 - 7x - 7 = - 6 + 3x \\ - 1 - 7x = - 6 + 3x[/tex]

[tex] - 1 + 6 = 7x + 3x \\ 5 = 10x \\ \frac{5}{10} = x \\ \frac{1}{2} = x[/tex]

[tex]6 - 7( \frac{1}{2} ) - 7 = - 6 + 3( \frac{1}{2} ) \\ 6 - \frac{7}{2} - 7 = - 6 + \frac{3}{2} \Longrightarrow \sf{You \: \: can \: \: change \: \: sides \: \: to \: \: make \: \: it \: \: easier} \\ 6 - 7 + 6 = \frac{7}{2} + \frac{3}{2} \\ 5 = \frac{10}{2} \\ 5 = 5 \: \green{ \checkmark}[/tex]

The equation is true for x = 1/2.

[tex] \large \boxed{x = \frac{1}{2} } \: \: \: \: \green{ \checkmark}[/tex]

Answer:

1. 300 and 330

2. the red car has better mileage

3. well I did 300 divided by 12 and got 25. then I did 330 divided by 15 and got 22 so the red has better mileage

Answer: 124 trips

Step-by-step explanation:

Miguel cycled for 246 kilometres to get to 41 trips.

You can use this to find out the distance of one trip.

= 246/41

= 6 km

Each trip was 6 km.

If Miguel wants to travel for 744 kilometres, the number of trips to make is:

= 744/6

= 124 trips

Answer:

9·x² - 36·x = 4·y² + 24·y + 36 in standard form is;

(x - 2)²/2² - (y + 3)²/3² = 1

Step-by-step explanation:

The standard form of a hyperbola is given as follows;

(x - h)²/a² - (y - k)²/b² = 1 or (y - k)²/b² - (x - h)²/a² = 1

The given equation is presented as follows;

9·x² - 36·x = 4·y² + 24·y + 36

By completing the square, we get;

(3·x - 6)·(3·x - 6) - 36 = (2·y + 6)·(2·y + 6)

(3·x - 6)² - 36 = (2·y + 6)²

(3·x - 6)² - (2·y + 6)² = 36

(3·x - 6)²/36 - (2·y + 6)²/36 = 36/36 = 1

(3·x - 6)²/6² - (2·y + 6)²/6² = 1

3²·(x - 2)²/6² - 2²·(y + 3)²/6² = 1

(x - 2)²/2² - (y + 3)²/3² = 1

The equation of the hyperbola  is (x - 2)²/2² - (y + 3)²/3² = 1.

Answer:

9 Litre of 100% acid, 27 Litre of 20% acid solution

Step-by-step explanation:

We know that 1 = 100% while

0.2 = 20%

We assume that x is volume of 100% solution, while y is volume of 20% solution.

x + 0.2y = (36×40/100)

x+0.2y= 14.4--------eqn(1)

x+y=36-------eqn(2)

x=36-y------eqn(3)

Input eqn(2) into 1 we have

(36-y)+0.2y= 14.4

-y+0.2y=14.4-36

-0.8y= 21.6

y=21.6/0.8

y=27

Hence, 27 Litre of 20% acid is required

From eqn(3) we can find value of x

x = 36-27

9 Litre of 100% acid is required

9 Litre of 100% acid, 27 Litre of 20% acid

Hence, the laboratory technician can combine a batch of 9 Litre of 100% acid, 27 Litre of 20% acid an acid solution that is pure acid with another that is ​20% to get the desired​ concentration

Answer:

24 degrees and 72 degrees

Step-by-step explanation:

4 EQUAL parts;

part 1, 2, and part 3 are all included in the bigger angle

part 4 is included in the smaller angle

96 (total) / 4 (parts) = 24 degrees

part 1 + part 2 + part 3 = 72 degrees

part 4 = 24 degrees

Your angle measures are 24 degrees and 72 degrees.
