3x-9=7x+14 solve for x
Answer:
x= - 23/4
Step-by-step explanation:
Add 9 to both sides of the equation:
3x -9 = 7x +14
3x- 9 + 9 = 7x +14 +9
Simplify:
3x -9 + 9 = 7x +14 +9
3x = 7x +14 +9
3x =7x +14 +9
Subtract 7x from both sides of the equation:
3x= 7x +23
3x -7x = 7x +23 - 7x
Simplify Again:
3x -7x = 7x +23 -7x
-4x =23
Combine like terms:
-4x =23
Divide both sides of the equation by the same terms:
14x/ 14 = 23/ -4
Cancel terms that are both the numerator and the denominator:
x= - 23/- 4
Answer:
x= - 23/4

After 6 months you have the same account balance as your friend and you have saved 280$. Write a linear equation that represents your account balance.
Answer:
y = 20x + 280
Step-by-step explanation:
The linear equation that represent your account balance is as follows:
Your friend
y = 25(6) + 250
= 400
And,
You
400 = m(6) + 280
6m = 400 - 280
6m = 120
m = 20
Now the equation of the account balance is
y = 20x + 280
Hence, the linear equation that represent your account balance is y = 20x + 280

Answer:
I will do the first one for you 115/24
Step-by-step explanation:
First find the prime number is of the number on the bottom of the fraction
Second after finding the prime numbers multiple all the times number starting with the bigger number’s prime number, and if the other prime number have a pair dont add them into equation. Ex 8-2 2 2 and 4-2 2 the 8 has 3 (2s) cancelling out the 4’s( 2s) other ex. 6-2 3 and 18- 2 3 3 the 18 has a 2 and 3 cancelling out the 6’s 2 and 3 making it multiple 2x3x3
Third after finding this number at step (2) this is the number at the bottom of the fraction making it easy to do any equations on it
Hope this helps :D

Answer:
The coordinates of the Midpoint of AB will be: (1/2, 5)
Step-by-step explanation:
Given the points
A(-2, 6)B(3, 4)Finding the midpoint between (-2, 6) and (3, 4)
[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-2,\:6\right),\:\left(x_2,\:y_2\right)=\left(3,\:4\right)[/tex]
[tex]M.P=\left(\frac{3-2}{2},\:\frac{4+6}{2}\right)[/tex]
[tex]=\left(\frac{1}{2},\:5\right)[/tex]
Therefore, the coordinates of the Midpoint of AB will be: (1/2, 5)
What is the slope of the line?
Answer:
Step-by-step explanation:
by inspection.. ( looking at the graph) we can see that the slope is down hill. so it's going to be negative and also slope = rise / run [rise is negative in this question] soo ... i'm looking carefully to see where the line is crossing the grid marks exactly .. it looks like to me (-3,1) and (2,-3) you tell me if that looks right... if it does .. then the rise / run is 4/5 and this is a negative slope sooo
- 4/5

A salesman needed to sell a used car. He priced it at $4,500 the first day it was on the
market. The second day he reduced the price by 12%. What was the price of the used car after this reduction?
Answer:
$3960
Step-by-step explanation:
12% of $4,500 is 540.
Subtracting the 12% means taking away $540 from $4,500, which gives you $3960

Which of the following is a point-slope equation for a line with the point
(-2, 4) and a slope of 3?
OA. y- 4 - 3(x+2)
OB. y+2 = 3(x- 4)
OC. y-2 - 3(x- 4)
OD. y- 4 - 3(x- 2)
Answer:
A. y - 4 = 3(x + 2)
Step-by-step explanation:
Point slope form is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line
Plug in the slope and given point:
y - y1 = m(x - x1)
y - 4 = 3(x + 2) is the equation
So, A is the correct answer.

A 16-ounce bag of cereal costs about $2.88. What is the unit rade of the cereal?
Answer:
18 cents per ounce
Step-by-step explanation:
The first step is to identify the unit. In this case, you are told you have 16-ounces. Therefore, your unit is an ounce.
To find the price of one ounce, just divide your price of $2.88 by 16.
Unit rate = $2.88 / 16 = 0.18 or 18 cents per ounce.
Write the slope intercept form of the graph plz
Answer:
y = 3x - 6
Step-by-step explanation:
slope intercept form is: y = mx + b
m is your slope, so figure it out by doing rise/run
you rise 3, over one which is 3/1, but simplifies to 3
b is your y-intercept, find it by seeing where the line crosses the y-axis, which is -6
therefore, your answer is: y = 3x - 6
