Answer:
3 x 2 − 2 x + 4 = 2 x 2 − 4
Step-by-step explanation:
Write the problem as a mathematical expression.
3 x 2 − 2 x + 4 = 2 x 2 − 4
Subtract 2 x 2 − 4 from both sides of the equation.
3 x 2 − 2 x + 4 − 2 x 2 − 4 = 0
Simplify each term.
Subtract 4 from 2 . 3 x 2 − 2 x + 4 − 2 x − 2 = 0
Rewrite the expression using the negative exponent rule
b − n =1 b n . 3 x 2 − 2 x + 4 − 2 1 x 2 = 0
Combine − 2 and 1 x 2 . 3 x 2 − 2 x + 4 + − 2 x 2 = 0
Move the negative in front of the fraction.
3 x 2 − 2 x + 4 − 2 x 2 = 0

Answer:
-3/4
Step-by-step explanation:
(-2,5) (10,-4) <-y2-y1 / x2-x1 is the equation
-4-5 -9 -9
---------- = --------- = -------- <-simplify this
10-(-2) 10+2 12
-9/3=-3
12/3=4
-3/4
Answer:
Option 3 (-3/4)
Step-by-step explanation:
To find the slope of a line, you find the change in y and divide it by the change in x:
5 - (-4) 9
--------- = ------
-2 - 10 -12
If you simply 9/-12 (they both go into the number 3), you get -3/4
x over 2 (as in fraction) minus 8 =y, solve for x
Answer:
x = 2y + 16
Step-by-step explanation:
[tex]\frac{x}{2} - 8 = y[/tex]
[tex]\frac{x}{2} - 8 + 8 = y + 8[/tex] (adding 8 to both sides)
[tex]\frac{x}{2} = y + 8[/tex]
[tex]\frac{x * 2}{2} = (y + 8)*2[/tex] (multiplying both sides by 2)
[tex]x = 2y + 8 * 2[/tex]
[tex]x = 2y + 16[/tex]

A meal costs $30 before tax and tip.
There is a 7% sales tax. After the tax, a 20% tip is
added.
What is the total after tax and tip?
Answer:
13.50
Step-by-step explanation:
you multiply 30 with 0.7 to get the tax then divide by 20% of that to get the answer
Answer:
bill = $30
sales tax = 0.07 from 70%
tip = 0.2 from 20%
After Tax BillAfter Tax Bill = Bill * (1 + sales tax)
After Tax Bill = $30 * (1 + 0.07)
After Tax Bill = $30 * 1.07
After Tax Bill = $32.1
Total after tax and tipTotal Bill = After tax Bill * (1 + tip)
Total Bill = $32.1 * (1 + 0.2)
Total Bill = $32.1 * 1.2
Total Bill = $38.52

This is a process that happens in most humans. most often happening to teenagers due to their increased hormones during their puberty. I would recommend getting attached to music as a form of reliance. I too had my days when I would be depressed but I got through it by attaching myself to something rather than someone. people's actions in real life during this time can seem exaggerated to you so it would be best to just ignore people for now if you are sensitive and just listen to music, study, or read a book to take your mind off the stress. However, based on the current trends I would recommend you to get attached to this thing called Kpop. recently I conducted a survey and many people said they were happier watching stuff about pretty people rather than going out and socializing. you could attach yourself to a particular idol and "stan" them as it would keep your mind off people. however, this method although effective can lead you to become a brain dead fan who will waste money and become a loner I suggest that if taking this idol attachment approach that you go out and try to connect with new people or try to reunite with your old people too so that you don't lose touch with reality. And lastly, it could be just that this Current situation stress is weighing too heavily on you and you have mistaken it and you just need a period of rest to get your bearings back. I recommend you try a period of resting and self-indulgence, then if that doesn't work music, and if the music doesn't work then attach yourself to an idol. Don't give up and try something new

ross had some stickers. He gave 297 of them to his sister.
if Ross gave 66% of the stickers to his sister, has may
shokers did he have
Answer:
Ross has 450 stickers.
Step-by-step explanation:
Ross gave stickers to his sister = 297
If 66% of stickers Ross gave to his sister, how many stickers does Ross have?
Let Ross have stickers = x
So, we can write:
[tex]66\% of x = 297[/tex]
Now solving this equation and finding value of x
[tex]66\% of x = 297\\\frac{66}{100}\times x = 297\\x=297 \times \frac{100}{66}\\x=450[/tex]
We get x = 450. We know x= Number of stickers Ross has
So, Ross has 450 stickers.

Brendan has six less than five times the number of pencils that Riley has. Let p represent the number of pencils Riley has. Write an algebraic expression that represents the number of pencils Brendan has in terms of p, the number of pencils that Riley has.
Answer: 5p - 6
Step-by-step explanation:
Brendan has six less than five times the number of pencils that Riley has.
P = the number of pencils Riley has.
The algebraic expression that represents the number of pencils Brendan has in terms of p, the number of pencils that Riley has would be:
= (5 × p) - 6
= 5p - 6
For example, if Riley has 5 pencils, the number of pencils that Brendan would have would be:
= 5p - 6.
= 5(5) - 6
= 25 - 6
= 19 pencils
write an equation in slope-intercept form for this line.
Answer:
y = [tex]\frac{3}{2}[/tex] x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = [tex]\frac{3}{2}[/tex] , then
y = [tex]\frac{3}{2}[/tex] x + c ← is the partial equation
To find c substitute (- 4, - 7 ) into the partial equation
- 7 = - 6 + c ⇒ c = - 7 + 6 = - 1
y = [tex]\frac{3}{2}[/tex] x - 1 ← equation of line

A customer at a Mexican diner placed an order for 3 burrito bowls which was priced at $x each. He also ordered a plate of corn tacos at $11 and was billed for a total of $32. Which equation represents the situation?
Answer:
x=$7
Step-by-step explanation:
The total cost of bill is $32, $11 is from a plate of corn tacos. And there are 3 purchased burrito bowls at a cost of $x each.
$32 (total bill)
-$11 (tacos)
=$21
$21 / 3 (burrito bowls)
=$7
x or the cost of each burrito bowl is $7
