The angles across from each other equal each other.

3y + 5 = y + 75 (subtract 5 from each side)

3y = y + 70 (subtract y from each side)

Y = 35

Do same thing with X.

Suppose a line graphed on a coordinate plane represents the distance traveled in miles by an automobile as a function of time in hours. Assuming that the Nationship between time and distance traveled is proportional, which of these statements is correct? Select one that applies

A. If the automobile was going 25 mph, the slope of the line is -1/25

B.If the automobile was going 30 mph, the slope of the line is 1/30

C.If the automobile was going 35 mph, the y-intercept of the line is 35.
D. If the automobile was going 40 mph, the y-intercept of the line is -1/40

E.If the automobile was going 45 mph, the y-intercept of the line is 1/45

F.If the automobile was going 50 mph, the slope of the line is 50.

Answers

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.

Answers

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

You have a total of 12 cards in four different colors. The probability of drawing a green card is the same as the probability of drawing a yellow card. The probability of drawing a red card is 1-4 and of drawing a blue card is 1-12. How many green cards are in the box

Answers

Answer:

4

Step-by-step explanation:

Let's start with the easiest bits.

     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.

Given the function f(x) = 2x + 5, what would the input be with an output of -9

Answers

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 :-

f ( x) = 2x + 5.

given output, f( x) = -9

plug the f(x) as -9.

-9 = 2x + 5

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

-9 - 5 = 2 x-14 = 2x

Divide both side by 2.

-14/2 = 2x / 2-7 = x

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

Jada has a job with the city’s Parks and Recreation Department. She receives an hourly wage plus time and a half for any hours over 40 worked each week.


Which piecewise-defined function best models her weekly pay h(t) if she works t hours and receives an hourly wage of $12?

(answer choices attached)

Answers

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:

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.

[tex]b = (5) - (8) * (1)[/tex] [tex]b = 5 - 8[/tex] [tex]b = -3[/tex]

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

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