What is the greatest common factor of 3x4, 15x3, 21x2
Answer:
[tex]3x^2[/tex]
Step-by-step explanation:
slope= -2/3 through: (3,-4)
Write the polynomial as an equation.
y=(−3,−4)
Rewrite in slope-intercept form.
The slope-intercept form is y = mx+b , where m is the slope and is the y-intercept.
y=mx+b
Remove the parentheses around the expression -3,-4.
y=−3,−4
The equation is not linear, so the slope does not exist.
Not Linear
If Ej bisects ZH&J, solve for z.
A. X= 41
B. X=47
C. X= 48
D. X= 49
Answer:
x = 47
Step-by-step explanation:
Bisect means split in half.
If El bisects ∠HEJ then the angles that are created from the bisected segment are congruent
Hence, ∠HEl = ∠JEI
If ∠HEl = x + 3 and ∠JEl = 3x - 91
and the two are congruent
then x + 3 = 3x - 91
Note that we've just created an equation that we can use to solve for x
we now solve for x
x + 3 = 3x - 91
add 91 to both sides
x + 3 + 91 = 3x - 91 + 91
x + 94 = 3x
subtract x from both sides
x - x + 94 = 3x - x
94 = 2x
divide both sides by 2
94/2 = 47
2x/2=x
we're left with x = 47

There are 2 of each angles
Please help I will appreciate it greatly. It’s my final question
Answer:
16
Step-by-step explanation:
Both angles are equal, so we just formulate the equation and solve for x.
x + 15 = 6x - 65
80 = 5x
16 = x
X = 16

Rearrange tiles on the board to represent equivalent
expressions.
Use the model to create zero pairs. What is an
equivalent expression that has two terms?
Board sum: 2x + (-x) + 3 + (-2)
Equivalent expressions are expressions of equal values
The equivalent expression of 2x + (-x) + 3 + (-2) is x + 1
How to determine the equivalent expressionThe expression is given as:
2x + (-x) + 3 + (-2)
Remove the brackets from the expression
2x -x + 3 -2
Evaluate the sums and differences in the above expression
x + 1
Hence, the equivalent expression of 2x + (-x) + 3 + (-2) is x + 1

Which steps should be used to graph the equation below? y-4=1/3(x+2)
-> First, we want to put it into more of a slope-intercept form so we can graph.
y - 4 = 1/3 (x + 2)
y = 1/3 (x + 2) + 4
y = 1/3x + 2/3 + 4
y = 1/3x + 14/3
-> Next, we will plot the point (0, 14/3) because it is the y-intercept of our equation
-> Last, we will move up one and to the right three, following the pattern of "rise over run" with our slope of 1/3
[] The finished graph is attached
[] I have also graphed the original equation to show that they overlap, showing that our simplification works

write the equation of the line that passes through the given points in slope intercept form
(2,6) (0,0)
Answer:
y=3x
Step-by-step explanation:
To put this in slope intercept form, let’s first find the slope
To find slope, use the equation Y2-Y1/X2-X1
When we do this, we get 0-6/0-2
This simplifies out into -6/-2 which is 3
So our slope is 3. Our equation becomes y=3x+b
Now, we find our b
We don’t have to do any solving for this, since we have the point 0,0 listed for us, it goes through the origin and that is our y-intercept or b
So our final equation is y=3x
Hope this helps and have a good day!

4(x+8)-4=34-2x show work
Answer:
x=1
Step-by-step explanation:
First, use the distributive property with 4(x+8), which equals 4x+32. So the right side is 4x+32-4. Combine like terms which will then give you 4x+28.
Next step is getting the variable on one side. So you have 4x+28=-2x+34 (I rearranged it because I personally like having the variable in the front). So, you should get rid of the smaller term first, in this case it's -2x. To cancel it out you have to add 2x to both sides. This will give you 6x+28=34.
Now you have to get the variable by itself. To do this you should first subtract 28 from both sides. This will leave you with 6x=6. The next step is dividing both sides by 6 to get your variable alone. This will leave you with x=1
So you're final answer is x=1.

The store paid $2.70 for a book and sold it for $6.20. What is the profit as a percent?
Answer:
129.6% profit
Step-by-step explanation:
1)Firstly in order to find the overall profit you take away $2.70 from $6.20 = $3.50
2)The next step is to put the profit over the amount paid = 3.50/2.70 = 35/27.
3)In order to find the percentaage you multiply 35/27 by 100 = 129.629 recurring. This rounded to 1 decimal place is 129.6%

John bought a skateboard for $60.00. He had to pay an additional tax of 8%.
What was the total cost of his purchase with tax?
Answer:
$4.80 was the tax so the entire cost would be 64.80
Step-by-step explanation:
0.08 x 60 = 4.8
then add that to $60 for cost before tax
so the answer would be 64.80
Answer:
$64.8
Step-by-step explanation:
$60 is 100% of the price of the skateboard or the price before tax was involved
Now, John has to pay a tax of 8%, or add 8% of the price of the skateboard to the total bill.
To increase by 8%, you must find 108% of 60, the price of the skateboard
To do this, you multiply 60 by 1.08
Solve:
108% of 601.08*60 = 64.8
John paid $[tex]\boxed{64.8}[/tex] for his skateboard

Please Help me do this
1. Old value = 5
New value = 10
Percent Change = 10 - 5 / 5 × 100%
= 5/5 × 100%
= 100% (increase)
2. Old value = 40
New value = 20
Percent Change = 20 - 40 / 40 × 100%
= -20/40 × 100%
= -1/2 × 100%
= -50% (decrease)
3. Old value = $50
New value = $40
Percent Change = $40 - $50 / $50 × 100%
= -$10/$50 × 100%
= -1/5 × 100%
= -20% (decrease)
