-3x + 4 = -8
Does anyone know what x is?
Answers
Answer:
x = 4
Step-by-step explanation:
-3x + 4 = -8
-3x = -8 - 4
-3x = -12
x = -12/-3
x = 4
Answer: x = 4
Step-by-step explanation: Move all terms that don't contain x to the right side and solve.
-3x +4 = -8
-4 -4
Subtract four from the four to cancel out and the -8.
That makes the equation -3x = -12
Then, divide by -3 by -3, then -12 divide by -3, to equal 4
Hope this helps and please mark me brainliest :)

Answers
Reason:
6 black out of 4+6+5 = 15 total
6/15 = 0.40 is the experimental probability of selecting black.
Side note: The term "empirical probability" is the same as "experimental probability".
The experimental probability of selecting a black marble will be 0.40. The correct option is C.
What is probability?Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favourable outcomes to all outcomes.
Probability = Number of favourable outcomes / Number of samples
Given that Michael has a bag of marbles. The frequency of selecting each colour is recorded in the table below. Outcome Frequency Green 4 Black 6 Orange 5.
Number of favourable outcomes = 6
Number of samples = 4+6+5 = 15
Probability = Number of favourable outcomes / Number of samples
Probability = 6 / 15
Probability = 0.40
Therefore, the probability will be 0.40.

Answers
The value of A/B is given as follows:
A/B = -2.
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:
B = -1 -> as x + B = 0 -> x = -B = -1.
When x = 0, y = -2, hence the value of A is obtained as follows:
A/-1 = -2
A = 2.
Then the division is given as follows:
A/B = 2/-1 = -2.

What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
The cost of electric toothbrush = $56
And, The price of markup = 40%
Now,
Since, The cost of electric toothbrush = $56
And, The price of markup = 40%
So, The cost for the store to purchase the electric toothbrush is;
= (40% of $56)
= (40/100 x 56)
= $22.4
Thus, The cost for the store to purchase the electric toothbrush will be;

Answer: Vaughn collected 72 pieces of litter.
Step-by-step explanation: The equation is correct. You get that by going backwards through the information in the story.
Vaughn's number is x.
Piper is 1/4 x
Sara is Piper +12 So (1/4 x)+12
Dom is Sara -15. So (1/4 x) -3
Add all Piper, Sara & Dom on one side of the equation.
The other side is the Vaughn's amount minus 9 because it says he picked up 9 more than the others combined. So x-9 equals the amount of the other three combined.
The three 1/4 x add to 3/4 x
Skipping to the solution:
x - 3/4 = 12 -3 +9
1/4 x = 18 Multiply both sides by 4
x = 72
1/4 x is 18, Piper's number.
Use that to calculate the Sara and Dominique.

What is a polynomial?Polynomial is an equation written as the sum of terms of the form kx^n.
where k and n are positive integers.
Example:
x² + 3x + 9 is an equation.
x³ + 6x² + 6x + 8 is an equation.
We have,

One of the roots of this equation is 5.
This means,
5² - 5b + c = 0
25 - 5b + c = 0
Adding 5b on both sides.
25 + c = 5b
Subtracting 25 on both sides.
c = 5b - 25
