Given the function f(x) = 2x + 5, what would the input be with an output of -9
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 + 5Move the constant to the left hand side and change their sign.
-9 - 5 = 2 x-14 = 2xDivide both side by 2.
-14/2 = 2x / 2-7 = xTherefore, the input of this function would be -7.

Step-by-step explanation:
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.
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.

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)
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 $

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
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.
Hope this helps!
Solve for a. 50 - a/11 = 58
Answer:
a = -88
Step-by-step explanation:
50− a/ 11 =58
50 + -1/11 x a = 58
-1/11 x a + 50 = 58
Subtract 50 from both sides
-1/11 x a - 50 (-50) = 58 (-50)
Now multiply both sides by 11/-1
(11/-1) x (-1/11 x a) = (11/-1) x 8
a = -88

Original: $39.99
New: _________
%Decrease: 15%
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

8: Harry is 3 years older and Andy is twice as old as
Sam. The total of their ages is 27. If Sam is x years old
form an equation using this information.
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:
b. two solution its very sample
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.
