If f(x) = 6x - 2, what is the value of f(4)?
O 16
O 22
O24
O26
Answer: 22
Step-by-step explanation:
6(4)-2
If f(x) = 6x - 2, the value of f(4) is 22. The correct option among the given ones is 2.
What is function?A function in mathematics is a relationship between a set of inputs (also known as the domain) and a set of outputs (also known as the range) that has the property that each input is related to exactly one output.
Functions are widely used in many branches of mathematics and are critical for modelling relationships between variables in fields such as science, engineering, and economics.
They are represented by equations or rules that specify how the output values are obtained from the input values.
The given function is f(x) = 6x - 2.
To find the value of f(4), we substitute x = 4 in the given function and evaluate:
f(4) = 6(4) - 2
f(4) = 24 - 2
f(4) = 22
Thus, the value of f(4) is 22, i.e., the correct option is 2.

A principal decides to survey the parents at her school to find out their opinion on
standardized testing. She calls randomly-chosen parents between 4:00 and 5:00 P.M.
every day for a week and collects data on their responses. Identify the population
and the sample. Give a reason why the sample could be biased.
Oa)
Population: All parents who respond to the survey
Sample: All parents with students at the school
Possible Bias: The parents who answered the phone may not be
representative of the whole population because younger parents are more
likely to answer the phone than older ones.
b)
Population: All parents with students at the school
Sample: All parents who respond to the survey
Possible Bias: Parents who are at home between 4:00 and 5:00 P.M. may not
be representative of the whole population.
Oc) Population: All parents with students at the school
Sample: All parents who respond to the survey
Possible Bias: Some parents do not like a particular teacher.

Matt was babysitting for friend's parents Saturday morning and was paid an $10 per hour for 3 hours. Later that evening, he was baby sitting for another couple that paid him $20 per hour for 5 hours. What was Matt's average rate of pay per hour for the day?
Answer:
$16.25 per hour
Step-by-step explanation:
Given that:
First babysitting pay :
$10 per hour
Duration = 3 hours
Earning = $10 * 3 = $30
Second babysitting pay:
$20 per hour
Duration = 5 hours
Earning = 20 * 5 = $100
Average rate of pay per hour for the day:
Total amount earned / total hours worked
$(30 + 100) / (3 + 5) hours
$130 / 8 hours
= $16. 25 per hour

Jackrabbits are capable of reaching speeds up to 40 miles per hour. How fast is this in feet per second? Round to the nearest whole number
Answer:
59 feet per second.
Step-by-step explanation:
Firstly, we need to convert miles into feet and hours into seconds.
We know that there are 5280 feet in a mile.
To convert hours into seconds we multiply how many minutes are in an hour by how many seconds there are in a minute (60x60) to get 3600.
We multiply 5280 by 40 to get 211200 feet per hour
Because of the word "PER" we know that this is a divison problem.
211200 divided by 3600 is 58.66 repeating. Rounded to the nearest whole number makes it 59 feet per second.

She needs to add one half of a teaspoon of salt, 1 and one fourth teaspoons of Oregano, three fourths of a teaspoon of Basil and half as much pepper as salt. What is the total number of teaspoons of spices in the dish? Express the answer as a decimal.
Answer:
Total number of teaspoons is 2.75
Step-by-step explanation:
Here, we want to know the total number of teaspoons of spices in the dish
we can calculate this by adding together the individual number of spices
That will be ;
1/2 + 1 1/4 + 3/4 + 1/2(1/2)
1/2(1/2) represents half as much pepper as salt
1/2 = 0.5
1 1/4 = 1.25
3/4 = 0.75
1/2(1/2) = 1/4 = 0.25
The total number of tea spoons will be;
0.5 + 1.25 + 0.75 + 0.25 = 2.75

Which values of x are solutions to this equation? |x/-4| = 2
-x = 4 or x = 8
-x = 2 or x = 6
-x = -2 or x = 2
-x = -8 or x = 8
Answer:
Step-by-step explanation:
|x/-4| = 2 corresponds to two different equations:
1) -x/4 = 2 if x/-4 is already positive, and
2) x/4 = 2 if -x/4 is negative, due to the absolute value operator
In case 1, -x = 8, or x = -8
and
in case 2, x = 8
so the solution set is {-8, 8}
Double check to ensure that you have copied down this problem correctly. Your " |x/-4| " looks odd/ambiguous

PLEASE HELP!! what is the value of x? what is the value of y?
Answer:
x=36° y=66°
Step-by-step explanation:
3x+6+x+30 = 180° (Supplementary angles)
4x+36 = 180
4x = 180 - 36
4x = 144
x = 36
y+3x+6 = 180° (Supplementary angles)
y+3*36+6 = 180 (plug in the value of x)
y+108+6 = 180
y= 180-108-6
y = 66
