Step-by-step explanation:
f(x) = x^2 - 3x - 4g(x) = | x +3 | -2--------
f(x) = g(x)1. For x+3 ≥ 0 ⇒ x ≥ -3, g(x) = x + 3 - 2
x^2 - 3x - 4 = x + 3 - 2x^2 - 4x - 5 = 0(x- 5)(x + 1) = 0x = 5, x = -1x = -1 is one of the options2. For x + 3 < 0 ⇒ x < -3, g(x) = - (x +3) - 2
x^2 - 3x - 4 = -(x + 3) - 2x^2 - 3x -2 = -x - 3x^2 -2x + 1 = 0(x - 1)^2 = 0x = 1 > -3, so no solutionslist 0.43, 5, 6 and 4.7 from least to greatest

13. Generalize in the diagram shown, if x + y = 180,
label the remaining angles
as x° or yº
Answer:
See attachment
Step-by-step explanation:
If x + y = 180°, the remaining angles can be labelled as illustrated in the diagram provided in the attachment below.
To properly label the diagram so that x° + y° = 180°, you must bear in mind or recall relation between angles formed when two parallel lines are cut across by a transversal line.
x° would be congruent to any angle that is either corresponding or vertical to it.
That is, for the angles labelled x°, such an angle is either corresponding to the given x° or it is vertically opposite to it.
Consequently, where the angle labelled y° forms a linear pair with x°. Linear pair of angles add up to give 180°.
Jennie is paid $10 an hour for regular time work and $20 an hour for overtime
work what is Jennie's gross pay for a week in which she works 22 regular time
hours and 4 V overtime hours? (1 point)
Answer:
Jennie earned $300
Step-by-step explanation:
We are already given the amount of time that she works and the rate. We just need to multiply the time by the corresponding rate. She worked 22 regular hours and gets $10 for each one. That means she earned $220 just from the regular hours.
Now we need to add the overtime hours. She worked 4 hours and made $20 for each one. In total, that's $80.
220+80=300
Jennie earned $300

What is a function?
A function in mathematics set up a relationship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.
The given function [tex]y = 2 -\sqrt{x+1}[/tex] and the point are ( x, -1.24 ). Put y = -1.24 in the given equation to get the value of x.
[tex]y = 2 -\sqrt{x+1}[/tex]
[tex]-1.24 = 2 - \sqrt{x+1}\\-1.24 - 2 = \sqrt{x+1}\\-3.24 = \sqrt{x+1}[/tex]
Squaring on both sides.
[tex](-3.24)^2 = (\sqrt{x+1})^2[/tex]
10.5 = x + 1
x = 9.5
Hence, the correct option is D.

Step-by-step explanation:
As part of a class project a university student surveyed students in the cafeteria to look for a relationship between the students eye color and hair color the table the survey results. The percentage of the sample population with brown eyes and black hair is larger than the percentage of the sample population with blue eyes and black hair by ___ percentage points. (Round off your answer to the nearest whole number.)
Answer:
18%
Step-by-step explanation:
There are 64 students with brown eyes and black hair, and 9 students with blue eyes and black hair. A total of 303 students were surveyed, so to find the percentage you would put the number of students with that trait over the total number of students surveyed. 64/303 = 21.1221%, and 9/303 = 2.9702%. 21.1221 - 2.9702 = 18.1519. When you round that to the nearest whole number, you get 18%. Therefore, the percentage of the sample population with brown eyes and black hair is larger than the percentage of the sample population with blue eyes and black hair by 18%.
Answer:
18%

What would the answer be and why?
Answer:
Solution: First option
Step-by-step explanation:
An increase in demand and a decrease in supply will cause an increase in the equilibrium price, but the effect on quantity is unclear.
Reasoning: For any quantity, the 'buyers' places a higher value on the goods, so the 'manufactures' must place higher values in order to distribute the good. Thus the price increases, but the output depends on the size of the two factors and which dominates, (1) pricing, (2) goods.
a jet travels 410 miles in 5 hours. At this rate, how far could the jet fly in 14 hours? What is the rate of speed of the jet
Answer:
Step-by-step explanation:
Rate X Time = distance
Therefore:
r (rate) X 5 (hours) = 600 (distance)
r = 600/5
r = 120 miles per hour
The rate of speed of the jet is 120 mph.
Then, to find out the distance flown in 13 hours:
120 (rate) X 13 (time) = d (distance)
120 X 13 = d
1560 = d
The distance flown in 13 hours is 1560 miles.

Blair's bank account was
overdrawn by $40. She spent $30 at the grocery store. What is the balance in her account now?
The addition is one of the four fundamental mathematical operations. Blair's bank balance after spending at the grocery store is -$70.
What is Addition?The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
Given that Blair's bank account was overdrawn by $40. Therefore, we can write her balance before spending at the grocery store as,
Blair's bank balance before spending at the grocery store = - $40
Now, Blair spent $30 at the grocery store. Therefore, she further takes $30 from her account. Thus, we can write Blair's bank balance after spending at the grocery store as,
Blair's bank balance after spending at the grocery store
= Blair's bank balance before spending at the grocery store + Spending
= -$40 + (-$30)
= -$40 - $30
= -$70
Hence, Blair's bank balance after spending at the grocery store is -$70.

How do you do this question?
Answer:
0.488
Step-by-step explanation:
Use binomial probability:
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
Here, n = 3 and p = 0.2.
The complement of at least 1 is at most 0.
P(r ≥ 1) = 1 − P(r = 0)
P(r ≥ 1) = 1 − ₃C₀ (0.2)⁰ (0.8)³⁻⁰
P(r ≥ 1) = 1 − (0.8)³
P(r ≥ 1) = 0.488

Solve the system below by substitution.
6x - y=-23
2x +5 y = -13
(-3,2)
(-4,-1)
(5,4)
(-4,1)
Answer:
[tex](-4, -1)[/tex]
Step-by-step explanation:
[tex]6x-y=-23[/tex]
Add y to both sides:
[tex]6x-y+y=-23+y\\6x=-23+y[/tex]
Divide both sides by 6:
[tex]\frac{6x}{6}=-\frac{23}{6}+\frac{y}{6}\\x=\frac{-23+y}{6}[/tex]
Substitute this into the second equation given:
[tex]2*\frac{-23+y}{6}+5y=-13[/tex]
[tex]\frac{-23+16y}{3}=-13[/tex]
Multiply both sides by 3:
[tex]-23+16y=-39[/tex]
Add 23 to both sides:
[tex]-23+16y+23=-39+23\\16y=-16[/tex]
Divide both sides by 16:
[tex]\frac{16y}{16}=\frac{-16}{16}\\y=-1[/tex]
We know that [tex]x=\frac{-23+y}{6}[/tex].
Thus, [tex]x=\frac{-23-1}{6}[/tex]
[tex]x=-4[/tex]
[tex](x, y) = (-4, -1)[/tex]
