Answer:
x=7
Step-by-step explanation:
divide both sides by two. distribute on the left side. minus 9x on both sides. add 4 on both sides, and you get 7.
Answer:
x = 7
Step-by-step explanation:
Firstly, use the distributive property to distribute the 4 and the 2 respectively.
[tex]4(5x-2) = 2(9x+3)[/tex]
[tex]20x-8=18x+6[/tex]
Then, isolate the variable. Start by subtracting 18x from both sides.
[tex]2x - 8 = 6[/tex]
Add 8 to both sides.
[tex]2x = 14[/tex]
Divide both sides by 2.
[tex]x=7[/tex]

Answer:
The first one.
Step-by-step explanation:
The line has a positive slope, so as x reaches infinity, f(x) will also reach infinity, and the same with negative. Hope this helps!

A washing machine is filling up with water at a constant rate. The rate is 3/4 of a gallon in 1/5 of a minute. Don calculated the unit rate to be 3/20 of a gallon per minute. what did he do wrong?
Answer: you have to see how many gallons fill the container per minute, so take 3/4 and divide it by 1/5, which gives 15/4. So he multiplied the two numbers instead of dividing.
Step-by-step explanation:
Answer:
[tex]\frac{15}{4}[/tex] gallon per minute
Step-by-step explanation:
Given parameters:
Quantity of gallon = [tex]\frac{3}{4}[/tex] gallon
Time taken = [tex]\frac{1}{5}[/tex] min
Unknown:
The solution is [tex]\frac{3}{20}[/tex] gallon per minute, what did he do wrong = ?
Solution:
To find the rate:
Rate = [tex]\frac{Quantity of gallon}{time }[/tex]
Input the parameters and solve
Rate = [tex]\frac{\frac{3}{4} }{\frac{1}{5} }[/tex] = [tex]\frac{3}{4}[/tex] ÷ [tex]\frac{1}{5}[/tex]
Invert the [tex]\frac{1}{5}[/tex] to give 5
= [tex]\frac{3}{4}[/tex] x 5
= [tex]\frac{15}{4}[/tex] gallon per minute
The student failed to invert the [tex]\frac{1}{5}[/tex] before multiplying with [tex]\frac{3}{4}[/tex]
Add:

[tex]if \: y = 2x + 5 \\ since \: x = 2 \\ y = 2(2) + 5 \\ y = 9. \\ hence \: the \: complete \: point \: is \to \\ \boxed{(2, \: 9) }[/tex]
♨Rage♨
Answer: (2, 9 )
========================================================
Explanation:
Any point is of the form (x,y). The x coordinate is always listed first.
We're given (2, ___) where the y value is missing in the blank.
So we're given x = 2.
Plug this into the given equation to find y
y = 2x+5
y = 2*2+5 ... replace x with 2
y = 4+5
y = 9
Therefore (2, ___) updates to (2, 9 )
An online store sells 236 hats per month how many hats are sold in a year
Answer:
Roughly 2,832 hats sold per year, if their numbers stay the same
Step-by-step explanation:
236*12 :3
Answer:

What is the slope? Please answer with a pic and some work
Answer:
m = rise over run
Rise: y/2 - y/1
Run: x/2 - x/1
m = slope
(x_1, y_1) = coordinates of first point in the line
(x_2, y_2) = coordinates of second point in the line
Step-by-step explanation:
Answer:
slope= (y2-y1)/(x2-x1)
1) (2-1)/(3-2)
=m=1
3) (5-4)/(2-2)
= UNDEFINED (vertical line)
5) (-6-6)/(3-(-3)
(-12/6)
= -2
CHECK
y=mx+b
6=-2(-3)+b
6=6+b
b=0
y=-2x connects both of these points on a graph
5/6 divide by 1/2 in simplest form
Answer:
1 2/3
Step-by-step explanation:
To divide fractions you do the Keep Change Flip tactic, meaning keep the first fraction change the operation to multiplication and reverse the second fraction.
So with that being said, 5/6*2/1 would be the equation you need to solve. This would give you 10/6 and you have to change that into a mixed number, 1 4/6 and you can reduce that to SIMPLEST FORM by dividing by 2. 4/2=2 and 6/2=3 so in the end you get 1 2/3.

What is 8,187 divided by 24 (not resulting in a decimal number)?
Answer:
8,187 divided by 24 is 341.125
Step-by-step explanation:
i hope this helps!
Answer:
The answer is 341.125.
But, if you want it without a decimal, you need to round.
You round up if the first number right of the decimal is over 5 or 5, and down if the first number to the right of the decimal is under 5.
Since the first number to the right of the decimal is 1, it is under 5.
So we round down.
So it would be 341.
The answer without a decimal is 341.

Solve for x.
10x + 44
8x - 23
Answer:
Simplifying
10x + 44 = 8X + -23
Reorder the terms:
44 + 10x = 8X + -23
Reorder the terms:
44 + 10x = -23 + 8X
Solving
44 + 10x = -23 + 8X
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-44' to each side of the equation.
44 + -44 + 10x = -23 + -44 + 8X
Combine like terms: 44 + -44 = 0
0 + 10x = -23 + -44 + 8X
10x = -23 + -44 + 8X
Combine like terms: -23 + -44 = -67
10x = -67 + 8X
Divide each side by '10'.
x = -6.7 + 0.8X
Simplifying
x = -6.7 + 0.8XStep-by-step explanation:

Given(x - 1)^2 + (y + 3)^2 = 13 x + y = -3SolutionFrom the second equation we get
x = - y - 3Substituting x in the first equation
(- y - 3 - 1)^2 + (y + 3)^2 = 13(-y - 4)^2 + (y + 3)^2 = 13(y+4)^2 + (y+3)^2 = 13y^2 + 8y + 16 + y^2 + 6y + 9 = 132y^2 + 14y + 12 = 0y^2 +7y +6 = 0(y+1)(y+6) = 0y = - 1y = - 6Then
