Describe in your own words how to tell if an equation has infinite solutions or no solution at all
Answers
Answer:
We can identify which case it is by looking at our results. If we end up with the same term on both sides of the equal sign, such as 4 = 4 or 4x = 4x, then we have infinite solutions. If we end up with different numbers on either side of the equal sign, as in 4 = 5, then we have no solutions.Step-by-step explanation:

Justify each step used to simplify the expression. 1. 3x+ 2y− 2x+ 2 = 3x− 2x+ 2y+ 2
Answers
Step-by-step explanation:
We have to simplify the given expression:
1. 3x+2y-2x+23x+2y−2x+2
Combining the like terms,we get the second step as
2. (3x-2x)+(2y)+(2)(3x−2x)+(2y)+(2)
Now, taking 'x' common from the first two terms, we get third step as:
3. (3-2)x+2y+2(3−2)x+2y+2
Now, simplifying the expressions among the like terms, we get fourth step as:

A wooden bench was originally priced at $50 but went on sale for 20% off. If Presley bought the wooden bench and paid a 5% sales tax, how much did he pay in total?
Answers
Answer:
$42.00
Step-by-step explanation:
20% OF 50 = 40
Before Tax Price: $40.00
Sale Tax: 5.00% or $2.00
After Tax Price: $42.00
Answer:
$42
Step-by-step explanation:
To get the new bench price, you multiply 50 × 0.2, which gets you 10, then you subtract 50-10, which is 40, and $40 is the price of the bench on sale. (You could also do 50 × 0.8 to avoid a step and still get the same answer).
You then take 40 and multiply is by 0.05 to get the tax, which would be $2. From here, you add 40+2 to get $42, the amount of money Presley paid for the bench.

For her cell phone plan, heather pays $30 per month plus $0.05 per month plus $0.05 per text. She wants to keep her bill under $60 per month. Which inequality represents the number of texts, t, Heather can send each month while staying within her budget?
A. T> 600
B. T<600
Answers
Answer:
A
Step-by-step explanation:
Answer: B. T<600
Step-by-step explanation:
if the monthly plan is $30, we subtract that from $60 to get that she has $30 left. Then divide 30 by 0.05 to get exactly 600. but, you can’t forget that other $0.05 per month so it would have to be less than 600 texts

The manager of a dress shop recorded the number of dresses sold during the week, the data is as follows:

Find the mean deviation for this data.
Select one:
1.91
2.21
1.67
4.98
Answers
Answer: The answer is 1.67
Step-by-step explanation:
First, find the mean by adding all of the numbers and divide them by how many numbers there are, so 17+15+16+20+15+19=102 Then 102/6= 17. Then take the mean and subtract it by every number, and make sure it is the number’s absolute value.
17-17=0, 15-17=2, 16-17=1, 20-17=3, 15-17=2, 19-17=2. Then add all of those numbers and divide them by how many numbers there are. 0+2+1+3+2+2=10. 10/6=1.67
Answer:

Step-by-step explanation:
To find the value of this equation when [tex]x=-2[/tex], we can substitute this value inside the equation and use PEMDAS to successfully find the value.
With the expression of [tex]2x^2+4x-3[/tex], let's substitute -2 in as x.
[tex]2(-2)^2 + 4(-2) - 3[/tex]Now let's follow PEMDAS to solve this equation.
PEMDAS states that when solving an expression/equation, the order we must follow is
ParenthesesExponentsMultiplication/DivisionAddition/SubtractionWe can now solve for this.
We see that exponents come before multiply and dividing. Therefore:
[tex]2(-2)^2 = 2 \cdot (-2)^2 = 2 \cdot 4 = 8[/tex]So the value of our first term is 8.
Our second term will be [tex]4 \cdot -2 = -8[/tex], and our last term will remain -3.
Adding these values together:
[tex]8 - 8 - 3 = -3[/tex]
Therefore, the value of this expression when x = -2 is -3.
