Answer: 4
Step-by-step explanation: First convert the equation to y = mx + b form.
Start by subtract 4x from both sides to get -y = -4x + 3.
From here, divide both sides by -1 to get y = 4x - 3.
Now in y = mx + b form, the slope is the multiplier, or the m.
So here, 4 is the slope.
Answer:
(D) 4
Step-by-step explanation:
In order to find the slope you need to rearrange the equation so that y is alone on one side, so:
4x - y = 3
-y = -4x + 3
y = 4x - 3
The slope is the coefficient in front of x, so the slope is 4

Are 12/16 and 6/9 equivalent? Explain your answer.
Answer:
No
Step-by-step explanation:
Times the numerator and denominator by 2. 6 does turn into 12, but 9 doesn't turn into 16. Therefore, these fractions are not equivalent.
Let f(x) = 16 - x^2, g(x) = 4 - x. Find (fg)(x) and its domain.
Answer:
(fg)(x) = x^3-4x^2-16x+64, D: All Real Numbers
Step-by-step explanation:
(fg)(x) = f(x) x g(x)
= 16-x^2(4-x)
=64-16x-4x+x^3
(fg)(x) = x^3-4x^2-16x+64
Domain is all real numbers because you can substitute any real number for x and the function would still work.
Thus the value of [tex](fg)(x) = x^3 -4x^2 -16x -64[/tex] , and the domain is a set of real numbers.
The domain is a set of all real numbers because by substituting any value in the equation we only get real numbers.
The function is defined as a relationship between two variables a dependent and an independent variable. A function consists of a domain and a co-domain. The set of codomains is called a range.
Example : [tex]f(x) = 4x+ 3[/tex]
All those values of a set for which a function is defined are called a domain.
According to the question :
[tex]f(x) = 16 - x^2\\ g(x) = 4 - x.[/tex]
[tex](fg)(x) = (16- x^2) (4-x)\\(fg)(x) = [16(4-x) -x^2(4- x)]\\\(fg)(x) = [64- 16x -4x^2+x^3]\\(fg)(x) = x^3 -4x^2 -16 x -64[/tex]
Thus the value of [tex](fg)(x) = x^3 -4x^2-16x-64.[/tex]

Use two colors of counters to show a way to make 5.color to show the counters . Write the numbers to show the pair that makes 5
Answer:
1 and 4, 2 and 3, and 5 and 0.
Step-by-step explanation:
Counters are used by educators to teach children how to do calculations like addition, subtraction, multiplication and division. Using color counters help to visualise the result from the operands in a calculation.
To get the pairs of numbers that adds to 5.
- Use the first color counter to mark out the five ones on the sheet.
- then with the second color counter, subtract one from the five ones.
- repeat the first two steps and increment the subtracted value until it gets to five.

Question 5 Rocko paid $12.50 for 25 game tickets. Louisa paid $17.50 for 35 game tickets. What is the constant of proportionality? Express your answer in decimal form.
Answer: k = $0.50
Step-by-step explanation:
The data that we have is:
Rocko paid: $12.50 for 25 tickets.
Louisa paid: $17.50 for 35 tickets.
Now, the question asks to find the constant of proportionality.
A proportional relation can be written as:
y = k*x
where k is the constant, and in this case, y is the price and x the number of tickets bought.
Then replacing with the values above, we have:
$12.50 = k*25
then:
k = $12.50/25 = $0.50
And the other data:
$17.50 = k*35
K = $17.50/35 = $0.50
So we have the same k in both cases, this means that the constant of proportionality is k = $0.50

What value of n makes the equation?
8n - 5 = -2n + 5 true?
Answer:
[tex]n=1[/tex]
Step-by-step explanation:
[tex]8n - 5 = -2n + 5[/tex]
First, add 5 to both sides.
[tex]8n-5+5=-2n+5+5\\[/tex]
[tex]8n=-2n+10[/tex]
Then, add 2n to both sides.
[tex]8n+2n=-2n+10+2n[/tex]
[tex]10n=10[/tex]
Finally, divide both sides by 10.
[tex]\frac{10n}{10}=\frac{10}{10}[/tex]
[tex]n=1[/tex].
Answer:
[tex]n=1[/tex]
Step-by-step explanation:
So we have the equation:
[tex]8n-5=-2n+5[/tex]
First, add 2n to both sides. The right side cancels:
[tex]10n-5=5[/tex]
Add 5 to both sides:
[tex]10n=10[/tex]
Now, divide both sides by 7:
[tex]n=1[/tex]

How do you write the converse of a conditional? How do you Write the contrapositive of a conditional?
Answer:
Converse- If q, then p. Contrapositive- If not p, then not q
Step-by-step explanation:
Let's say your conditional is if an angle is 90 degrees then it is a right angle.
Then the converse is, if an angle is a right angle then it is 90 degrees.
Finally, the contrapositive is if an angle is not 90 degrees then it is not a right angle.

different intervals. The prize table allows volunteers a short break every 20 minutes, but the
refreshment table allows a short break only every 30 minutes. If the party is scheduled to start
at 2:00 pm and Brad and Stella both start working then, what is the first time that they will be
on break together? Show all work.
Answer:
They will be able to have their break together in 60 minutes.
Step-by-step explanation:
You will have to find the least common multiple (LCM) between 20 and 30.
The prime factorization of 20 is: 2 x 2 x 5
The prime factorization of 30 is: 2 x 3 x 5
Eliminate the duplicate factors of the two lists, then multiply them once with the remaining factors of the lists to get lcm(20,20) = 60

In a box there are 3 red pens, 2 green pens, and 1 blue pen. What is the probability of picking a red pen, not replacing it, and then picking a blue pen
Answer:
1/10
Step-by-step explanation:
First, find the probability of choosing the red pen:
There are 6 total pens and 3 are red, so the probability will be 3/6
This can be simplified to 1/2
Then, find the probability of choosing a blue pen after not replacing the red one:
There are 5 total pens now, since we did not replace the red one.
There is only 1 blue pen, so the probability is 1/5
Then, multiply these 2 probabilities together:
1/2(1/5)
= 1/10
So, the probability is 1/10

Answer:
[tex]x=3/2=1.5[/tex]
Step-by-step explanation:
So we have the equation:
[tex]49=7^{2x-1}[/tex]
Note that 49 is the same as 7 squared. Thus:
[tex](7)^2=(7)^{2x-1}[/tex]
Since they now have the same base, the exponents must be equal to each other. So:
[tex]2=2x-1[/tex]
Add 1 to both sides:
[tex]3=2x[/tex]
Divide both sides by 2:
[tex]x=3/2=1.5[/tex]
And we're done!
