3. Austin solved the equation as shown below. Which describes the error
that Austin made in his work?
Austin's Work:
-3 + 7x - 9 + 8x = 54
15x - 6 = 54
15x = 60
x = 4
A. Austin did not combine 7x and 8x correctly.
B. Austin did not combine -3 and -9 correctly.
C. Austin did not divide correctly
D. Austin did not make an error in his work.
Answer:
B. he didn't combine -3 and -9 correctly
The error that Austin made in his work is Austin did not combine -3 and -9 correctly.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that solved the equation -3 + 7x - 9 + 8x = 54 as shown below.
-3 + 7x - 9 + 8x = 54
15x - 6 = 54
15x = 60
x = 4
We need to check where did Austins has done wrong.
-3 + 7x - 9 + 8x = 54
15x-12=54
For Austin while combining -3 and -9 he got -6 which is wrong.
So Austin did not combine -3 and -9 correctly.
Hence, the error that Austin made in his work is Austin did not combine -3 and -9 correctly.

70 cds in 2022
Step-by-step explanation:
each year number of dvds being sold is decreasing by 15. In 2010, it was 250. 5 years later, it was 175.
250-175=75.
75/5=15.
15x7=105.
175-105=70.
in 2010 it was 250 and 250+150=400.
in 2000, it was y=400-15x

Answer:
2x-3y=2
x=6y-5
2(6y-5)-3y=2
use the distributive property.
2*6y=12y
2*-5=-10
12y-10-3y=2
combine like terms
12y-3y=9y
9y-10=2
add 10 to both sides.
9y-10+10=9y
2+10=12
9y=12
divide both sides by 9
9y/9=y
y=about 1.33
plug in the value of y in the expression equal to the value of x.
x=6(1.33)-5
solve
6*1.33=7.98
x=7.98-5
7.98-5=2.98
Step-by-step explanation:
x=2.98
y=1.33

What is the conjugate and modulus of 2 – 6i?
Answer:
2 + 6i
Step-by-step explanation:
It’s the same numbers with an opposite sign
The conjugate of 2 – 6i is 2 + 6i and the modulus is [tex]\sqrt{40}[/tex]
The conjugate of a complex number a + bi is a - bi. The conjugate is gotten by changing the sign of the imaginary part of the complex number.
The modulus of a complex number a + bi is:
|a + bi| = [tex]\sqrt{a^2+b^2}[/tex]
The conjugate and modulus of 2 – 6i is:
Conjugate of 2 - 6i = 2 + 6i
|2 - 6i| = [tex]\sqrt{2^2+(-6)^2}=\sqrt{40}[/tex]
The conjugate of 2 – 6i is 2 + 6i and the modulus is [tex]\sqrt{40}[/tex]

Create an equation (using the word bank) that describes Lizzie's investment based on t,
the number of years she kept the account open.
Word Bank:

Step-by-step explanation:
The way to approach the problem is this
After one year she has 2000*1.05
After two years she has the money from the last year plus interest, so she has 2000*1.05*1.05
After t years she has 2000*1.05

You’re starting a lemonade stand in front of your house. You’ve already obtained a permit from City Hall in order to do so. For your stand, your neighbor agrees to let you use his nice large table for $5 per day (this cost is known as fixed cost because it will not change whether you sell one cup or 100 cups of lemonade). Your parents give you full access to the fridge’s filtered water but require you to take care of the cost of the other ingredients and expenses that go into making your final product. After a day or two of starting your business, you determine that the cost of paper cups, sugar and fresh lemon juice is $0.32 per cup (this cost is known as variable cost because it changes according to the number of cups you sell).
