What is the coefficient: 4 - 2y
Answers
hope that helped!
The coefficient of the variable y for the given equation 4 - 2y is -2.
What is the coefficient?A coefficient is a number that is being multiplied by the variable, i.e. the numerical term with variable, that is a number that is placed before another variable. While the variable represents some quantity, it may also represent a number, a function, etc. The letters a, b, c, x, y, and z are common symbols used for variables.
We have,
An equation 4 - 2y,
So,
In the above-given expression,
We have only one variable and one Constant term,
i.e.
Constant term = 4
And,
Variable term = -2y
So,
In the variable term,
The coefficient of y = -2
So,
The coefficient of y is -2.
Hence, we can say that the coefficient of the variable y in the given equation is -2.

Tell whether the relation is a function. Explain.
Answers
Answer:
It is not a function.
Step-by-step explanation:
A relation can only be a function if every input (x-value) of the set of values of the relation, has exactly one output (y-value).
In the relation given, one input, -2, has two output related to it, 5 and 0. That's (-2, 5) and (-2, 0).
Therefore, the relation is not a function.

At the Red Apple Health Food Store, employees earn time and a half for any hours they work in addition to their regular 35-hour work week. Nicole Logan is paid $8.00 an hour. This week she worked 46.25 hours. What is her total pay?
Answers
Answer:
I think the answer is either $375.625
Step-by-step explanation:
If we multiple the usual 35 hours a week by 8 we get $280. Then we need to multiply the remaining extra hours (11.25) by 8.5 since the amount earned is 8 and a half more. Then we add 280+95.625=375.625
find the value of x then classify the triangle by its angles
Answers
Answer:
Step-by-step explanation:
3x + x + 60 = 180.
first, we add the x's together.
4x + 60 = 180
then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.
x + 15 = 45
then, just subtract 15 from both sides, that way we get the variable by itself.
x = 30
also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.
Step-by-step explanation:
3x+X+60=180
4x=180-60
X=120/4
X=30

Step-by-step explanation:
To find the slope of a line, you need to find the [tex]\frac{rise}{run}[/tex] between two points. I will be using the points (-3, 2) and (-1, -2).
[tex]\frac{rise}{run}[/tex] = [tex]\frac{-2-2}{-1-(-3)}[/tex]
= [tex]\frac{-2-2}{-1+3}[/tex]
= [tex]\frac{-4}{2}[/tex]

3. Jada can bake 12 cookies in 20 minutes. How many cookies can she bake 1
in 6 hours? HINT: 20 minutes and 6 hours are not equal, the hours MUST be
turned to minutes.
Answers
Answer:
she can bake 216 cookies in 360 minutes
Step-by-step explanation:
Answer:
Jada can bake 216 cookies in 6 hours.
Step-by-step explanation:
We need to know how many she can cook in 6 hours.
She currently bakes 12 every 20 minutes
we know that 1 hour is 60 minutes.
So we multiply 12 by 3 to get 36 because we know 60 minutes divided by 20 minutes is 3 minutes.
Now we know that she bakes 36 cookies in 1 hour
But it asked for 6 hours so simple multiplication:
36 cookies per 1 hour X 6 hours
36X6= 216

Complete Question
If the p-value for your test statistic in a test of hypothesis (for example, a t-test, one-tail) is 0.07 and the significance level alpha is set at 0.05, you conclude that:
A
Both hypotheses H0 and H1 can be accepted
B
The null hypothesis H0 cannot be rejected
C
The null hypothesis H0 can be rejected
D
The research hypothesis H1 can be accepted
Answer:
The correct option is B
Step-by-step explanation:
From the question we are told that
The p-value is [tex]p-value = 0.07[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
Generally given that it is a one tail test then the possible value of
The null hypothesis is [tex]H_o : \mu = x[/tex]
Here [tex]\mu[/tex] is the mean and x is the value
the possible values of the alternative hypothesis is [tex]\mu > x \ \ or \ \ \mu < x[/tex]
Now from the value given we see that the [tex]p-value > \alpha[/tex] hence

The book store earned x dollars in profit. Last week, the total profit
increased by 5%. Which expression represents the book store's total
increase in profit?
Answers
Answer:
x + 0.05x
Step-by-step explanation:
Given
Earnings earned by the bookstore = x
percentage increase = 5%
Increment = 5% of x
Increment = 0.05x
book store's total increase in profit = Original earning + increment
book store's total increase in profit x + 0.05x
Hence the expression that represents the book store's total increase in profit is x + 0.05x
