Answer:

33.99

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 39.99 × 15/100

Discount = 39.99 x 0.15

You save = $6.00

Final Price = Original Price - Discount

Final Price = 39.99 - 5.9985

Final Price = $33.99

Answer:

Approximate ≈ $33.99

Step-by-step explanation:

Original: 39.99

New: x

Percent Decrease: 15%

15% of 39.99 = 0.15(39.99) = 5.9985

39.99 - 5.9985 = 33.9915 = 33.99

Answer:

y = 8x - 3

Step-by-step explanation:

1. The slope-intercept form of any linear equation is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.

2. Since we're already given the slope, 8, our equation looks like this so far: y = 8x + b.

3. We can use the formula [tex]b = y_1 - m * x_1[/tex] to find the y-intercept.

4. Since b = -3, our equation now looks like this: y = 8x - 3.

Therefore, the correct answer is y = 8x - 3.

Answer:

18x + 6 = 6(3x + 1)

2x + 4= 2(x + 2)

Explanation:

For 2x +4:

group the common factor

2x + 4

and you'll get 2(x + 2)

For 18x + 6:

You'll do the same thing

18x + 6

The inequality is 10j is less than or equal to 130

10j ≤ 130

Answer:

Step-by-step explanation:

Disagree.  (4, 4) and (4, 5) show that for a single input, 4, there are two distinct outputs (4 and 5).  In a function no more than 1 output can be associated with a given input.

The given relation is not a function.

Step-by-step explanation:

given,

Harry = 3yrs

Andy = 2x ( twice as old as sam )

sam = x

their sum = 27

a/q

→ 2x + x + 3 = 27

→ 3x = 27 - 3 = 24

→ x = 24/3 = 8

→ x = 8

therefore, age of sam is 8 and Andy is 16 and Harry is 3.

the equation is

2x + x + 3 = 27

hope this answer helps you..and may u have a great day ahead!

The equation formed using the information given is x + (x + 3) + 2x = 27. Sam is 6 years old. Let x be Sam's age.

According to the given information:

1. Harry is 3 years older than Sam, so Harry's age is (x + 3) years.

2. Andy is twice as old as Sam, so Andy's age is 2x years.

3. The total of their ages is 27, so we can add their ages together and set it equal to 27:

x + (x + 3) + 2x = 27

Now, let's simplify the equation:

Combine like terms:

x + x + 3 + 2x = 27

Combine the x terms:

4x + 3 = 27

Now, we want to isolate the variable x on one side, so let's move the constant term (3) to the other side of the equation by subtracting 3 from both sides:

4x = 27 - 3

4x = 24

Finally, solve for x by dividing both sides by 4:

x = 24 / 4

x = 6

So, Sam is 6 years old.

Answer:

The input is -7

Step-by-step explanation:

f(x) = 2x + 5,

Let f(x) = -9

-9 = 2x+5

Subtract 5 from each side

-9-5 =2x+5-5

-14 =2x

Divide by 2

-14/2 =2x/2

-7 =x

Answer:

The would be -7.

Step-by-step explanation:

Given function :-

given output, f( x) = -9

plug the f(x) as -9.

Move the constant to the left hand side and change their sign.

Divide both side by 2.

Therefore, the input of this function would be -7.

The answer to the question which of these statements is correct is F. If the automobile was going 50 mph, the slope of the line is 50.

Since distance traveled in miles is graphed as a function of time in hours, this implies that distance is on the y-axis and time in hours is on the x-axis.

So, the slope of the graph is distance/time and its unit is miles/hour = miles per hour = mph.

This slope represents the speed of the automobile.

So an automobile going at 50 mph represent the slope of the line which is 50.

The answer to the question which of these statements is correct is F. If the automobile was going 50 mph, the slope of the line is 50.

Step-by-step explanation:

As per the problem statement, there is a linear relation,  between de whole earnings of Jada,  and her working time.

Solution:

y = 240 + 6×t

A Linear relation  is of the form:

y = ax + b

If we call total earnings´Jada "y",  and "t" the whole quantity of worked hours per week,  we get:

a fixed amount working 40 hours      12×40 = 480 $

and the quantity over 40 hours as   ( t - 40 ) × 6.

Then  y = fixed quantity + overtime

y = 480 + ( t - 40 ) × 6       reordering this expression

y = 480 + 6×t - 240

y = 240 + 6×t

Just for checking,  if this equation satisfies, the conditions of the problem

if t = 40 h    that means she did´nt do any overtime,

she earns    y = 240 + 6×(40)   ⇒  y = 480 $

if t = 50 h  meaning 10 hours of overtime, she earns:

y = 240 + (50)×6   ⇒  y = 540 $

Answer:

C: No solutions.

Step-by-step explanation:

When solving an equation and it provides a false statement, it implies that there are no values that could satisfy the given equation.  Simply put, the word "equation" in itself must provide equal values on either sides of the equal sign.

“No solution” means that there is no value, not even 0, which would satisfy the equation.

Therefore, the correct answer is C: No solutions.

     We know the probability of drawing a red card is 1/4, this means every four cards there is one red. So, 12/4 = 3, there are 3 red cards in the 12 card pile.

    Next, we are also given the probability of drawing a blue card us 1/12. In the same fashion, we can figure out there is 1 blue card.

Finally, we are told the probability of drawing a green card is the same as drawing a yellow card. Therefore there is the same amount of green cards as yellow.

There are 8 cards left that are green or yellow, as 12 - 1 - 3 is 8. 8/2 is 4, so there are 4 green cards in the box.
