We can describe 12x - 8 as an expression.
It can also be written as 4(3x - 2)
4 and 3x - 2 are both
of 12x - 8
Answer:
factors
Step-by-step explanation:
Since
12x - 8 = 4(3x - 2) ← in factored form
This means that 4 and 3x - 2 are factors of the expression

What is the domain of y = tan x? A. (–∞, ∞) B. C. all D. all
Given:
The function is
[tex]y=\tan x[/tex]
To find:
The domain of the given function.
Solution:
We know that, domain is the set of x-values or input values.
We have,
[tex]y=\tan x[/tex]
[tex]y=\dfrac{\sin x}{\cos x}[/tex]
The functions sin x and cos x are defined for all real values of x. So, the function tan x is defined for all real values of x except those value for which cos x = 0.
So, domain is [tex]-\infty<x<\infty, x\neq \dfrac{\pi}{2}+n\pi[/tex].
Note: All options are incorrect.
Answer:
C
Step-by-step explanation:
all x≠pi/2+pi n

what is volume of a trapezoid prism?
Answer:
If the prism length is L, trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2. In other words, multiply together the length, height, and average of A and B.

If your insurance plan is $15,000 and you pay for 20%, how much do you
pay monthly? *
2 poir
$250
$3,000
$57.69
$300
Answer: 250
Step-by-step explanation:
20% of 15,000 is 3,000
3,000/12=250
Answer:
$3000 Per Month
Step-by-step explanation:
Hi there,
How I like to solve these is first take the total number (15,000) and divide it by 100 to then find how much 1% of 15,000 is.
So :
15,000 / 100
=
150
Now we know :
1% = $150
We need to find 20% now so all we do is multiply.
150 x 20
($150 x 20%)
= $3,000 Per Month
I hope this helps!

The length, l , of a rectangle is 3 cm longer than twice the width, w. The perimeter of the rectangle is 66 cm.
Which system of linear equations could be used to find the length and width of the rectangle?
A. l = 3w + 2
2l + 2w = 66
B.l = 3w + 2
l + w = 66
C.I= 2w + 3
l + w = 66
D. l = 2w + 3
2l + 2w = 66
Answer:
The system of linear equations that could be used to find the length and width of the rectangle will be:
l = 2w + 3 cm
2w + 2l = 66
Hence, option D is correct.
Step-by-step explanation:
Let the width of the rectangle be = w cm
Given that the length, l, of a rectangle is 3 cm longer than twice the width, w.
Thus, the length of the rectangle be:
l = 2w + 3 cm
We know that the perimeter of the rectangle is:
P = 2w + 2l
Given that the perimeter of the rectangle = P = 66 cm
so substitute P = 66 in P = 2w + 2l
P = 2w + 2l
66 = 2w + 2l
Therefore, the system of linear equations that could be used to find the length and width of the rectangle will be:
l = 2w + 3 cm
2w + 2l = 66
Hence, option D is correct.
Work out the difference, in minutes, between 1 hour 50 minutes and 1 3/4 hours
Answer:
Step-by-step explanation:
1 hour nd 50 = 60 min +50 min= 110 minutes
1 hour and 3/4= 60/4= 15 x 3= 45
1 hour and 3/4= 60 min + 45 min= 105 minutes
110- 105= 5 minutes difference
5 minutes
1/4 of an hour is 15 minutes so times that by three you get 45 minutes. 50 minutes - 45 minutes = 5 minutes,

Page 5. 5, 6, 7, 8
Page 6. 12.5
Page 7. 4(3x)
Page 8. 0, 4
i don't know number 7
Answer:
9, 10
12.5
4 + 3x
0, 4
Step-by-step explanation:
5. This just looks to be some simple multiplication so lets work this out 1 by 1 .
Plugging each answer possible into m this is what we get :
8 x 5 = 40
8 x 6 = 48
8 x 7 = 56
8 x 8 = 64
8 x 9 = 72
8 x 10 = 80
Considering these answers lets find which ones are GREATER than 67.
That would be :
72, 80
So your answers would be :
9, 10
6. Alright so this one is asking you what the value of q would be in the equation :
0.5q = 6.25
So to find q we need to see that whatever q is will be multiplied by 0.5. And this answer will be equal to 6.25 due to the = sign. So an easy way of doing this is actually just finding what 6.25 x 2 is. Since q x 0.5 will equal to 6.25, finding 6.25 x 2 is just flipping the equation in a way.
So doing this we get 12.5 which is the very top answer of that question.
8. Alright so it looks like this question is just meant to make your brain turn into a raisin when you read it, but it isn't that hard.
Lets lay everything out :
Joe is 4 more than triple the age of luke.
x represents lukes age (x = Lukes age)
And we are finding the expression that shows joes age.
Alright so looking at the problem lets look at the key word MORE. More means addition in the math world usually so lets go off that. Lucky for you that's all you need cause you only have one addition answer here but lets still go over it why don't we.
4 + 3x
4 represents the "4 MORE than lukes age"
Then we have 3. The 3 represents the "triple the age of luke"
And finally x represents Lukes age.
So if we do 3 multiplied by x (Lukes age) we get triple lukes age :
4 + (Triple lukes age)
So now we just add the 4 and it would be in theory :
Triple Lukes age + 4 = Joes age. And that's all they want.
And then finally we have 7.
This is one fairly simple just another one meant to confused you a bit it seems.
You're basically taking the variable which is q and adding +2 to it and checking to see if the sum of that is less than 7.
So lets do that with the answers given
We will just input the number where q is in the equation and then check! :
2 + 0 < 7
2 plus 0 is 2, and is less than 7!
2 + 4 < 7
2 plus 4 is 6, and is less than 7!
2 + 5 < 7
2 plus 5 is 7. It would be correct if there was an equal sign or less than or equal to sign. But there is not so this is incorrect.
2 + 7 < 7
2 plus 7 is 9, which is greater than 7.
2 + 9 < 7
2 plus 9 is 11, which is greater than 7.
So lets look at what we plugged in that is less than (<) 7 and those are our answers! :
0 , 4
The others are either equal or greater than 7 which is not what we are looking for. So the only two correct answers here are 0, 4.
I hope this helps you! If you have any questions feel free to ask them in the comments and I will help you the best I can! :)
4. Emily ate dinner at Geisha. Her total was $17.50. A 8% sales tax was
added to her bill. After, Emily added a 20% tip on the total after tax. What
was Emily's final total?
*
Answer: $22.68
Step-by-step explanation:
17.50 times 0.08 = 1.40
17.50 + 1.40 = 18.90
Now the tip:
18.90 times .2 = 3.78
18.90 + 3.78 = 22.68
