Answer:
Take the square root of a number that is not a perfect square. None of the numbers are perfect squares. After you do that you can do any closed operation you want with the resulting irrational and the two other rationals and you will end up with an irrational.
8*24*√5 is an example.
8+24+√5 is another
5*√8 + 24 is another.
If you take the cube root of any number that isn't a perfect cube you get an irrational, so you could take the cube root of 5 or 24 instead of the square root and do the same thing.

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.

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.

a = b(h)
h = a/b
Sub:
a = 12x^2 + 38x + 20
b = 3x + 2
12x^2 + 38x + 20 = 3x + 2 * h

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.
