Answer:
x = 1/2 or x = -5/2
Step-by-step explanation:
Solve for x over the real numbers:
abs(12 x + 12) = 18
Hint: | Eliminate the absolute value.
Split the equation into two possible cases:
12 x + 12 = 18 or 12 x + 12 = -18
Hint: | Look at the first equation: Isolate terms with x to the left hand side.
Subtract 12 from both sides:
12 x = 6 or 12 x + 12 = -18
Hint: | Solve for x.
Divide both sides by 12:
x = 1/2 or 12 x + 12 = -18
Hint: | Look at the second equation: Isolate terms with x to the left hand side.
Subtract 12 from both sides:
x = 1/2 or 12 x = -30
Hint: | Solve for x.
Divide both sides by 12:
Answer: x = 1/2 or x = -5/2

What is the discriminat of 9x²+2=10x
Answer: 28
Step-by-step explanation:
The discriminant in the quadratic equation which is
it is the part inside of the square root part
it is called the discriminant beause it tells you how many real or complex roots/solutions you will get
so b^2-4ac
convert to ax^2+bx+c=0 form
9x^2+2=10x
subtract 10x
9x^2-10x+2=0
ax^2+bx+c=0
a=9
b=-10
c=2
substitute
-10^2-4(9)(2)
100-36(2)
100-72
28
discriminant is 28

Answer:
22 ft.
Step-by-step explanation:
First we can get the total change in elevation, which should be the final elevation minus the initial elevation:
(98ft)-(10ft)=88ft
Then, to get the change in 4 equal intervals, we can divide the total change in elevation by 4.
(88/4)ft=22ft
So during each of the four intervals, assuming they were four equal intervals, the diver descends 22ft.
what is the answer to 6(2x+3)-6
Answer:
12x+12

Daniela sells handmade purses for $22. She
makes $15 after expenses for each purse she
sells. She has $71 in the bank. How many
purses will she need to sell in order to have a
total of $161 in the bank?
Answer:
6 purses
Step-by-step explanation
1. Subtract 71 from 161 as that's how much Daniela needs to make to have 161, which is 90
2. Divide 15 by 90 as 15 is the profit, so the answer would be the amount of purses she needs to sell, then you get 6
Check
6 times 15, 90
71 + 90 = 161

Answer:
[tex]8i^{22}[/tex] - 1
Explanation:
It's actually quite easy to tell which simplifies to a real number without working out the problem.
[tex]i^{2}[/tex] = -1
Any imaginary number with an even exponent is simplified to a real number. If it has an odd exponent, it cannot be simplified to a real number.
Some tips for fully solving the expression:
If the exponent is divisible by 4, then don't change the sign of the coefficient. You're just multiplying it by 1 because [tex]i^{4}[/tex] = [tex](i^{2})^{2}[/tex] = [tex](-1)^{2}[/tex] = 1
If the exponent is divisible by 2, change the sign of the coefficient because you're multiplying it by -1.

In the expression 3v – 8, what is the variable?
Answer:
V is the variable
Step-by-step explanation:
Answer:a. v
Step-by-step explanation:
Given
Required
Identify the variable
Literary, variable means things that change in values;
Going by this definition, we have that:
3 -> This is not a variable because its value will always be 3
v -> This is a variable because its value can change once its value changes, the result of the expression will also change
- -> This is not a variable; it is an arithmetic operator to subtract
8 -> This is not a variable because its value will always be 8
Take for instance
When
Notice that there's a difference in both results;
This is as a result of v being a variable
Step-by-step explanation:
Miguel did the following math problem: 65 ∙ 64 = 369. Which of the following is a true statement? 1.He is correct. 2.He is incorrect because he should have subtracted the exponents. 3.He is incorrect because he should have multiplied the exponents. 4.He is incorrect because he multiplied the bases.
Answer:
He is incorrect.
Step-by-step explanation:
The correct answer is 4,160.
Answer:
3. He is incorrect because he should have multiplied the exponents.
Step-by-step explanation:
6∧5 × 6∧4 = 369 Incorrect
Correct: 6∧5 = 7776
6∧4 = 1296
7776 × 1296 = 10,077,696
1. He is not correct, therefore the first answer is wrong.
2. You do not subtract the exponents unless one of the exponents is negative and you have the same bases. You have the same bases in this equation, however, neither one of them are negative. Therefore, the second answer is wrong.
3. The third answer is correct because if you were adding the two terms together then you would add the exponents together then multiply the base as many times as needed. However, since you are multiplying the two terms together, you also need to multiply the exponents together. From there, you then multiply the terms and get your answer.
4. The fourth answer is also incorrect because you need to multiply the bases together in order to get a correct answer.

The sum of 20.7 and a number is 50.5.
Answer:
x = 29.8
Step-by-step explanation:
x represents the unknown number
20.7 + x = 50.5
x + 20.7 - 20.7 = 50.5 - 20.7
x = 50.5 - 20.7
x = 29.8
