Explain how solving -7y > 161 is different from solving 7y > -161.
Answers
To solve -7y > 161, we divide both sides by -7 and we get y < -23. The inequality sign flipped because we divided both sides by a negative number.
To solve 7y > -161, we divide both sides by 7 and it leads to y > -23. The inequality sign does not flip in this case, because we are not dividing both sides by a negative number.
The similarities is that we end up with -23 on the right side, but the inequality signs are different.

What is inequality?The relation between two unequal expressions is defined as inequality.
The given inequality is 4x+ 5y <100.
(A) Check the inequality for (16,8):
4(16) + 5(8) < 100
64 + 40 < 100
104 < 100
The inequality is false.
(B) Check the inequality for (15,8):

If the polynomial function is not given in factored form:
Factor out any common monomial factors.

x- intercepts.
A polynomial that has at least one x-intercept, will have at least one factor.

The given parameters are:
[tex]\mathbf{x-intercepts = (-6,0)\ and\ (2,0)}[/tex]
The x intercepts, represent the value of x, when the function equals 0.
So, the x values at the x-intercepts are:

Set these equations to 0

Answers
divide 2 with 128 and that will be the answer to x
2 divided by 128 = 64
x=64
The required value of the x in the expression 2x = 128 is x = 64.
Given that,
An expression is given 2x = 128, to determine the simplified value of the x.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The given expression is,
2x = 128
Dividing both the sides by 2
2x / 2 = 128 / 2
x = 64
Thus, the required value of the x in the expression 2x = 128 is x = 64.

Shelby Industries has a capacity to produce 45,000 oak shelves per year and is currently selling 40,000 shelves for $32 each. Martin Hardwoods has approached Shelby about buying 1,050 shelves for a new project and is willing to pay $26.8 each. The shelves can be packaged in bulk; this saves Shelby $1.14 per shelf compared to the normal packaging cost. Shelves have a unit variable cost of $25.4 with fixed costs of $350,000. Because the shelves don’t require packaging, the unit variable costs for the special order will drop by $1.14 per shelf. Shelby has enough idle capacity to accept the contract. What is TOTAL the profit/loss if Shelby should accept for this special order?
Answers
Answer:
y = mx + c
since m = 0
c = 9
$350,000 + $25.4 = y value
The total loss is $347,115 for Shelby if they accept the special order.
What is the profit?The profit is equal to the difference between the selling price and the original cost price.
To find the profit or loss for Shelby if they accept the special order, we need to calculate their total revenue from the sale and subtract their total costs.
First, let's calculate the total revenue from the sale of the 1,050 shelves to Martin Hardwoods. The price per shelf is $26.8, so the total revenue is 1,050 shelves x $26.8/shelf = $28,020.
Next, we need to calculate the total cost of producing and packaging the shelves. The unit variable cost is $25.4 per shelf, but because the shelves don't need to be packaged, the unit variable cost will be reduced by $1.14 per shelf. This means the unit variable cost for this special order is $25.4 - $1.14 = $24.26 per shelf.
The total cost of producing the 1,050 shelves is 1,050 shelves x $24.26/shelf = $25,135.
Finally, we need to add in the fixed costs of $350,000. This means the total cost of the special order is $25,135 + $350,000 = $375,135.
To find the profit or loss, we subtract the total cost from the total revenue: $28,020 - $375,135 = -$347,115.
Therefore, the total profit or loss for Shelby if they accept the special order is a loss of $347,115.

We are given:

Concepts used:
Evaluating Mixed fractions and Adding like terms
Simplifying the Mixed Fractions:
to simplify these mixed fractions, we will multiply the whole number part with the fraction's denominator and add that to the numerator.
The number formed will be given the same denominator as of the fraction part in the number
After simplifying these mixed fraction, we get:
[tex]\frac{16}{5}x + \frac{97}{9}x - \frac{12}{5}x - \frac{98}{9}x[/tex]
Adding and Subtracting the like terms:
to simplify our calculations, we will pair the numbers with the same denominator
[tex](\frac{16}{5}x - \frac{12}{5}x) + (\frac{97}{9}x - \frac{98}{9}x)[/tex]
Simplifying the terms in the brackets
[tex]\frac{4}{5}x - \frac{1}{9}x[/tex]
Taking the LCM and simplifying
[tex]\frac{36}{45}x - \frac{5}{45}x[/tex]
Since the denominators are equal, the numerators can now be subtracted
[tex]\frac{31}{45}x[/tex]
Therefore, simplifying the given series of number gives us 31x/45
