Start by combining like terms cancelling out the smaller one.
4x(-2x)-16=2x(-2x)+6
Then cancel out -16 so you get the variable x by itself.
2x-16(+16)=6(+16)
Then divide both sides by 2 to get x value.
2x/2=22/2

In ANOVA, which of the following is not affected by whether or not the population means are equal? between-samples estimate of o 2 within-samples estimate of o 2 None of these alternatives is correct.
Answers
In Analysis of variance, X (bar) is not affected by whether or not the population means are equal.
Analysis of variance is a statistical method for examining differences in means. It consists of a number of statistical models and the accompanying estimating techniques (such as the "variation" within and between groups). Ronald Fisher, a statistician, created Analysis of variance. The rule of total variance, on which the Analysis of variance is based, divides the observed variance in a given variable into components owing to various causes of variation.
ANOVA generalizes the t-test beyond two means by offering a statistical test to determine if two or more population means are equal. In other words, the Analysis of variance is employed to determine whether two or more means differ from one another.

Amazon sells slime in packs of 15 for $45.15. Rebecca and Elyssia are selling their own slime during breaks in packs of 5 for $20.35. Who has the better deal; Amazon or the girls?
Answers
Amazon has a better price, their rate is more cheaper.
The person with the better deal can be calculated as follows ?
Amazon sells the slime as 15packs for $45.15
The price of one pack can be calculated as follows
15= 45.15
1= x
Cross multiply both sides
15x= 45.15 × 1
15x= 45.15
divide both sides by the coefficient of x which is 15
15x/15= 45.15/15
x= 3.01
one pack of slime at Amazon is $3.01
The girls sell 5 packs of slime for $20.35
The price of one pack can be calculated as follows
5= 20.35
1= y
cross multiply both sides
5y= 20.35
y= 20.35/5
y= 4.07
The girls sell 1 pack of slime for $4.07
Therefore the person with the best deal is Amazon because their price is much more cheaper

Emma notices that since her credit card balance compounds monthly, she is charged more than 15% of her initial loan amount in interest each year. she wants to know how much she would pay if the card were compounded annually at a rate of 15%. which expression could emma use to evaluate her balance with an annual compounding interest rate?
Answers
Emma could use the expression 300(1.15)^t to calculate her amount using a compound interest rate every year.
We know that Compound interest, also known as interest on principal and interest, is the process of adding interest to the principal amount of a loan or deposit.
The interest one earns on the previous interest is known as compound interest.
For eg - if you have $100 and it generates 5% interest annually, you will have $105 at the end of the first year.
We will have $110.25 at the end of the second year.
Now, here we know that:
Interest rate = 15%
Now, compound interest formula is given by
A = P(1 + r/n)^nt
Upon putting the values, we get 300(1.15)^t.
Therefore, Emma could use the expression 300(1.15)^t, to calculate the amount using a compound interest rate every year.

A manufacturer has determined that the combined fixed and variable expenses for the production and sale of 500,000 items are $10,000,000. What is the price at the breakeven point for this item?
Answers
The breakeven point is the point at which a company's revenue is equal to its costs. In this case, the combined fixed and variable expenses for the production and sale of 500,000 items are $10,000,000, so the breakeven point for this item would be $10,000,000 / 500,000 items = $100000000/500000=$20 per item.
To determine the price at the breakeven point, we need to know the total revenue that the company is aiming to achieve. If the company's goal is to sell the items at a price above the breakeven point in order to make a profit, then the price at the breakeven point would be $20 per item.
However, if the company is simply trying to recover its costs, then the price at the breakeven point would be the same as the breakeven point, or $20 per item.

Step-by-step explanation:
6x [tex]\geq[/tex]15
x= $2.5
since it deals with money make it $2.50
_made my kharis:)
Carson expects to spend at least $15 on the popsicles, so the cost of each popsicle multiplied by the number of popsicles he is buying (6) must be greater than or equal to $15. Therefore, the inequality 15 ≤ 6x describes the problem.
Step 1: Let x represent the cost of each popsicle.
Step 2: Multiply 6 (the number of popsicles) by x (the cost of each popsicle): 6x
Step 3: Set the equation equal to 15 (the amount of money Carson expects to spend on the popsicles):
6x = 15
Step 4: Divide both sides of the equation by 6:
6x/6
= 15/6
Step 5: Simplify to get the answer:
x = $2.50
Carson wants to buy 6 popsicles from the ice cream truck and expects to spend at least $15. To figure out how much each popsicle should cost, I used an inequality. I let x represent the cost of each popsicle, multiplied it by 6 (the number of popsicles Carson is buying), and set the equation equal to 15 (the amount of money Carson expects to spend). After dividing both sides of the equation by 6 and simplifying, I got the answer that each popsicle should cost $2.50. Therefore, Carson should expect to spend at least $15 on the 6 popsicles.

Answers
The domain and the range of the function is (d) D: {x ∊ ℝ | x ≠ -4}; R: {y ∊ ℝ | y ≠ 3}
The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
The domain of the function
We have the function to be
f(x) = \frac{x^2 + 5x + 4}{x + 4}
Set the denominator to 0
x + 4= 0
Solve for x
x = -4
This means that the domain of the function is the set of all real numbers except -4
Hence, the domain of the function is {x ∊ ℝ | x ≠ -4}
The range of the function
We have the function to be
f(x) = \frac{x^2 + 5x + 4}{x + 4}
Factorize the numerator
f(x) = \frac{(x + 1)(x + 4)}{x + 1}
Simplify
f(x) = x + 4
The function is undefined at x= -1.
So, we have:
f(-1) = -1 + 4
f(-1) = 3
This means that the range of the function is the set of all real numbers except 6
Hence, the range of the function is {y ∊ ℝ | y ≠ 3}

The domain of the function, f(x) = (x² + 5x + 4)/ (x + 4) is set of all real numbers except -4 and range of the function is set of all real numbers except -3.
Therefore the answer is d: {x ∊ ℝ | x ≠ −4}; r: {y ∊ ℝ | y ≠ -3}.
The domain of the function f is the set of all values of x for which the function is defined. In this case, the function is not defined when the denominator, x + 4, is equal to 0, which occurs when x = -4.
Therefore, the domain of the function is {x ∊ ℝ | x ≠ −4}.
The range of the function is the set of all possible values of y that the function can take on.
y = (x² + 5x + 4)/ (x + 4), that is
[tex]y = \frac{x^{2}+5x+4 }{x+4}[/tex]
[tex]y = \frac{x^{2} +x + 4x+4 }{x+4}[/tex]
y = (x + 4)(x+1)/(x + 4), that is
[tex]y = \frac{(x + 4)(x + 1) }{x+4}[/tex]
y = x + 1
x = y - 1
At x = -4
-4 = y -1
y = -3
But x ≠ -4, so y ≠ -3
In this case, the function can take on any value, except -3.
Therefore, the range of the function is {y ∊ ℝ | y ≠ -3}.

= 1 × 1! + 2 × 2! + . . . + k × k! + (k + 1) × (k + 1)!
= (k + 1 )! - 1 + (k + 1) × (k + 1)!
= (1 + k + 1)(k + 1)! - 1
= (k + 2)(k + 1)! - 1
= (k + 2)! - 1
= ((k + 1) + 1)! - 1
This means, T(k+1) is also true.
So, T(n) is true for all positive integers n .
Hence proved.
