Answer:

Option D is correct

Step-by-step explanation:

With x < 4 and y < 5:

P = 4x + 3y < 4(4) + 3(5) = 16 + 15 = 31

=> Option D is correct

Given the equation P = 4x + 3y  With constraints x > 0, x < 4 and y < 5:

Option D is correct that is 31.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Given the equation P = 4x + 3y

With  constraints x > 0, x < 4 and y < 5:

The maximum value is

P = 4x + 3y < 4(4) + 3(5)

P = 16 + 15

P = 31

Hence, the Option D is correct.

Step-by-step explanation:

First, we have the base of the value that is $120, now we know that the overhead is 5%, so we must calculate this value in dollars, the 5% of $120 is:

This value you must add to the base ($120), so the cost with the overhead is $126. How the store wants to make a profit of 10%, you must calculate this 10% of the total cost obtained ($126):

And you must add this value to obtain the final price in the store:

Answer:

13/4 * 5/2

Step-by-step explanation:

In the question, it says that her coach wants her to run 2 1/2 TIMES the original 3/4 she had ran. Therefore, you would want to make the fractions into improper fractions, and then multiply, which is how you would get 13/4 * 5/2.

12-3*y = 0

Subtract 12 from both sides:

-3 * y = -12

Divide both sides by -3:

y = 4

Answer:

y=4

Step-by-step explanation:

Standard form:

−3y + 12 = 0

Factorization:

−3(y − 4) = 0

Solutions:

y = 12/3   = 4

Isolate the variable by dividing each side by factors that don't contain the variable:

y=4

Answer:

f(2)= 2, f(3)= -9

Step-by-step explanation:

To find f(2) o f(3), you simply plug the respective number into the function, substituting it for x:

f(2)= -3(2)^2 + 4(2) + 6

f(2)= -12 + 8 + 6

f(2)= 2

f(3)= -3(3)^2 + 4(3) + 6

f(3)= -27 + 12 + 6

f(3)= -9

Answer:  y = 3x + 1

Step-by-step explanation:

In the equation y=mx+b (slope - intercept form), m represents the slope and b represents the y - intercept of the equation. We can use this to answer the problem.

Because the problem specifies here that the equation we are trying to solve for is parallel to y= 3x - 5, we can assume that its slope is 3 (the same as the line it is parallel to - this is so because of the definition of parallel lines).

m = 3

And finally, we know that the y-intercept will be in the form (0, b) - which is exactly what the given point is in. Substitute the value in, and we get:

b = 1

Now put these two values into one equation.

y = mx + b

y = (3)x + (1)

y = 3x + 1

Answer:

The answer will be 7L/100km.

Step-by-step explanation:

The fuel consumption rate is already given for the first 100 km. So, the next 500 km will be 100km to 600km. You have to find the slope of the line during this travel. If you observe, the fuel lowers from 40 litres to 5 litres in this 500km journey. That means, 35 litres were used for 500km. Divide both with 5. That gives 7litres per 100km.

Hey there! :)

Answer:

x = 7L/100km.

Step-by-step explanation:

Solve this problem by using the slope formula:

[tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Use the points (100, 40) and (600, 5) and plug these into the formula:

[tex]m = \frac{5-40}{600-100}[/tex]

Simplify:

[tex]m=\frac{-35}{500}[/tex]

Since this is describing the rate of consumption, we can simply write the slope as:

[tex]m = \frac{35}{500}[/tex]

The question is asking for the rate of consumption over 100 km, therefore:

[tex]\frac{35}{500} = \frac{x}{100}[/tex]

Cross multiply:

3500 = 500x

Divide both sides by 500:

3500/500 = 500x/500

x = 7L/100km.

Answer:

Applies are £0.50 each and bananas £0.80 each.

Step-by-step explanation:

Represent the numbers of apples and bananas by a and b respectively.

Then:

5a + 4b = £5.70, and:

4a + 2b = £3.60

Let's solve this system using elimination by addition/subtraction.  Multiply the 2nd equation by -2, obtaining the equivalent system

5a + 4b = £5.70

-8a  - 4b = -£7.20

--------------------------

-3a         =  -£1.50

Dividing both sides by -3, we get £0.50.  Apples are £0.50 apiece.

How much are bananas per piece?  Use the first equation; substitute £0.50 for a:

5(£0.50) + 4b = £5.70, or

                  4b = £3.20.  Then b = £0.80.

Applies are £0.50 each and bananas £0.80 each.

Answer:

y = 8x - 26

Step-by-step explanation:  

Since we already have the ending equation in slope intercept form, all we need to do is fill in the blanks. We do that by putting it in point slope form which is [tex]y-y_{1}=m(x-x_{1})[/tex]

(You can plug either point in and get the same result but I'm going to use the first one)

[tex]y-(-2)=8(x-3)[/tex]

Distribute the [tex]m(x-x_{3})[/tex]

[tex]y-(-2)=8x-24[/tex]

Isolate the [tex]y[/tex]

[tex]y-(-2)=y+2[/tex]

Step-by-step explanation:

After folding the piece of paper, the result will be 1/4 the size of the original square. If you multiply the are of the triangle by 4, you will find that the area of the original square is 36 square inches.  The square root of 36 is 6, which shows us that the length of each side of the square is 6. To get the perimeter, multiply 6 by 4 to get 24 inches.

Answer:

0.43 is the answer

Step-by-step explanation:

you need to take the total of action movie and divide it by the grand total.

204/478 ≈ 0.43

The  probability that a randomly chosen person from this group an action movie is 0.43.

Probability refers to the idea that an event may or may not happen. The scenario described here is a mutually exclusive event. We must recall that in cases of a mutually exclusive event, we add probabilities.

Hence;

Probability of a male watching an action movie = 105/479

Probability of a female watching an action movie = 99/479

probability that a randomly chosen person from this group an action movie = 105/479 +  99/479 = 0.43

Answer:

1/5

Step-by-step explanation:

We can find the slope of a line using two points by

m = (y2-y1)/ (x2-x1)

    = (3-2)/(4 - -1)

    (3-2) /( 4+1)

     1/5

Answer:

B. 1/5

Step-by-step explanation:

The slope can be found through two points.

m = rise/run

m = (y2 - y1)/(x2 - x1)

m = (3 - 2)/(4 - (- 1))

m = 1/(4+1)

m = 1/5

Th slope of the line going through the points  (-1, 2) and (4, 3) is 1/5.

Answer:

The exponential function represented by the values is f(x) = 4(0.5)ˣ.

An exponential function is in the form:

y = abˣ

where y, x are variables, a is the initial value of y and b is the multiplier.

From the table, at point (0, 4):

4 = ab⁰

a = 4

At point (2, 1):

1 = ab²

1 = 4b²

b² = 0.25

b = 0.5

The exponential function represented by the values is f(x) = 4(0.5)ˣ.
