Answer:
32
Step-by-step explanation:
to form a linear pair means when the two angles are added, they equal 180 degrees
3x + 20 + x + 32 = 180
4x + 52 = 180
4x = 128
x = 32

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

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.

A student said that the relation{(-2,3),(4,4),(4,5),(5, -8)} is a function. Do you agree? Why or why not?
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.

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!

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 $

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.
