Consider the problem: Jasmine wants to buy a brand new pair of headphones that cost $99. While she already has $40 saved up, she is planning on working at a local grocery store for $8 an hour to make up the extra cash. Which of the following inequalities will help her determine values of h, the number of hours that Jasmine can work so she can afford the new headphones?

Answer:

$325

Step-by-step explanation:

Let the dryer price be x, then the washer price would be x-78

x+x-78 = 572

2x = 650

x = 325

For the given cost equation we have:

a) Fixed cost is $900.

b) For making 25 items the cost is $1150.

c) D: x ∈ [0, 150]

   R: c ∈ [900, 2400]

Here we know that the cost equation is:

c(x) = 10*x + 900.

First, we want to get the fixed cost, it is given by evaluating the function in x = 0.

c(0) = 10*0 + 900 = 900

The fixed cost is 900.

b) Now we want to get the cost for making 25 items, to get this, we just evaluate in x = 25.

c(25) = 10*25 + 900 = 250 + 900 = 1150

c) Now, if the maximum cost is 2400, then the maximum number of items that we can make is x₀, such that:

c( x₀) = 2400 = 10*x₀ + 900

Solving for x₀ we get:

x₀ = (2400 - 900)/10 = 150

Now we want to get the range and domain.

We know that we can make between 0 and 150 items, so the domain is:

D: x ∈ [0, 150]

For the range, we know that the fixed cost for 0 items is 900, and the maximum cost is 2400, then the range is:

R: c ∈ [900, 2400]

Step-by-step explanation:

The Surface Area of the cone 12π cm².

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. The theorem can be used to determine how steep mountains or slopes are. To calculate the distance between an observer and a location on the ground when the observer is looking down from a tower or structure. It is mostly utilized in the construction industry.

Given,  A cone with the height of 2√3 and the radius of base is 2 cm.

Since, Surface are of Cone = rlπ + B

Where l= slant height, and B = area of the base

In our case,

r = 2

B = π * r*r = π* 4

for slant height,

Slant makes a perfect right angle triangle with the center line thus,

from Pythagorean theorem,

l² = (2√3)² + 2²

l² = 12 + 4

l = 4 cm

Thus,

Surface area for the Cone = π * 2 *4 + π * 4

Surface area for the Cone = 12π

therefore, Surface Area of the cone 12π cm².

d = r/t

d = 40/40

d = 1 hour

Step-by-step explanation:

just think : what does 40 mph mean ?

it stands for

40 miles per hour

it means with that speed you will drive 40 miles in 1 hour.

20 miles in 1/2 hour.

80 miles in 2 hours and so on.

you always have to multiply both sides of the ratio with the same factor to keep the ratio itself unchanged.

so, as per the definition, it takes 1 hour to drive 40 miles when going 40 mph.

The solution to the inequality is (7/6, ∝) and (-∝, 7/6)

The inequality expression is given as:

2−5|6x−4|<−13

Subtract 2 from both sides

|6x−4|<−15

Divide through by -5

|6x−4| > 3

Remove the inequality sign

6x - 4 > 3 or 6x - 4 < 3

Add 4 to both sides

6x > 7 or 6x < 7

Answer:

8x + 16

Step-by-step explanation:

(f - g)(x) = f(x) - g(x)

g(x) = -(x+4)(x+4)

= -(x² + 4x + 4x + 16)

= -(x² + 8x + 16)

= -x² - 8x - 16

Answer:  -1/9  which is choice B

Explanation:

The term "zeros" refers to the x intercepts.

Plug in y = 0 and solve for x.

y = -9x-1

0 = -9x - 1

9x = -1

x = -1/9

1) The equation of the parallel line in Slope Intercept Form is; y = -x - 1

2) The equation of the perpendicular line in Slope Intercept Form is;

y = ³/₂x - 4

1) When two lines are parallel, it means their slopes are the same.

Formula for equation in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Thus, slope of y = -x + 1 is m = -1.

Equation of parallel line is;

(y - (-5))/(x - 4) = -1

y + 5 = -x + 4

y = -x - 1

2) When two lines are perpendicular, it means their slopes are the negative inverse of each other. Thus;

Slope of line = -2/3 and so slope of perpendicular line = 3/2. Thus, equation of new line is;

(y + 1)/(x - 2) = 3/2

2y + 2 = 3x - 6

2y = 3x - 8

y = ³/₂x - 4

The permutation shows that when one has been cast yet, the different ways that are there to cast Fantine from the 28 women is 28.

The different ways that are there to cast Fantine from the 28 women will be:

When Fantine has already been cast, the number of ways that are there to cast adult Cosette from the remaining women will be:

Step-by-step explanation:

Step: Solve −x+4y=4 for x:

−x+4y+−4y=4+−4y(Add -4y to both sides)

−x=−4y+4

-x/-1 = -4y+4/-1 (Divide both sides by -1)

x=4y−4

−x+3y=1

−(4y−4)+3y=1

−y+4=1(Simplify both sides of the equation)

−y+4+−4=1+−4(Add -4 to both sides)

−y=−3

-y/-1 = -3/-1 (Divide both sides by -1)

Let the function will be

f: X → Y

Then the inverse function will be

f⁻¹: Y → X

The function is given below.

f(x) = 5x – 3

Then the value of the function f(x) at x = 5, will be
