Answer:
the answer is:
4 - 4x+ 2x = -3x -3
4 - 2x = -3x -3
4 + 3 = -3x +2x
7 = -x
x = (-7)
Answer: -7
Step-by-step explanation:
4(1 – x) + 2 x = –3( x + 1)
Simplify the parentheses
4 - 4x + 2x = -3x - 3
Combine like terms
4 - 2x = -3x - 3
Subtract like terms on each side of the equal sign to isolate variable
x=-7
function contains the ordered pairs (0, 3), (6, 1), and (9, 0). Which statement explains whether or not the function is linear?

Helped need plzs , due by 11:59
Answer:
x = 10
Step-by-step explanation:
The two triangles are similar, and it says that VUT is similar to EFG so side VT corresponds to side EG which means that 8 is just side VU divided by 2.
This means that side EG is 14 divided by 2 and that is 7.
This results in the equation " 2x - 13 = 7" First, add 13 to both sides of the equation to get rid of the -13. This gives 2x = 20. Then divide both sides by two to cancel out and get rid of the 2 in 2x. This leaves x as 10.
1. Write the equation of the circle given the following information. *
Center (-8,-9) and a radius r= 10
Answer:
(x+8)² + (y+9)² = 100
Step-by-step explanation:
The equation for a circle on a graph is
(x - a)² + (y - b)² = r²
r represents the radius
a represents the x displacement of the circle's center.
b represents the y displacement of the circle's center.

"The definition of good mathematical problem is the mathematics it generates rather than the problem itself"
Andrew Willes
ANSWER:People interpret things differently there have been math problems that were told to be unsolved until someone viewed it differently and solved it. If you never try it, you will never solve it. Some problems seem simple but you try them for a year, ten years, a hundred years and it turns out they are extremely hard to solve. Simple but challanging math problems. The Good Math problems are those that look simple but are hard to solve. The problem itself looks simple But the math it generates is hard and complex to solve.
It is saying that to have a good mathematical problem depends on what that problem is (generates)
Some mathematical problems will be easier or harder than others.
But It is saying that the definition of a good problem is because it's mathematical not what the quesiton is.
what is the answer to this radical equation
[tex]\sqrt{x + 13=7}[/tex]
Answer:
x = 36
Step-by-step explanation:
Given
[tex]\sqrt{x+13}[/tex] = 7 ( square both sides )
([tex]\sqrt{x+13}[/tex] )² = 7²
x + 13 = 49 ( subtract 13 from both sides )
x = 36
[tex]\sqrt{x+13}=7\\[/tex]
To solve the radical equation, completing the square all whole equation.
[tex](\sqrt{x+13})^2=7^2\\[/tex]
As defined, [tex](\sqrt{x})^2 =|x|[/tex]
Therefore, [tex](\sqrt{x+13})^2=|x+13|=x+13[/tex] (Although Absolute Function gives 2 conditions, however - domain of radical function must be greater than or equal to 0. Meaning x < 0 for another condition doesn't apply.)
[tex]x+13=49\\x=49-13[/tex]
Move 13 to subtract.
[tex]x=36[/tex]
Therefore, the answer is x = 36.

Answer:
6/4 = 3/2
just count the rise/run
Step-by-step explanation:
Answer:
The slope is 3/2
Step-by-step explanation:
We'll call the bottom point (-3,-2) and the top point (1,4). We could rise/run the rise would be 6 units and the run would be 4 units. And we can simplify 6/4 to 3/2.

What is the y-intercept of the function?
Answer:
-5
Step-by-step explanation:
The square root of the quotient of a number n and 3 is equal to the square root of 4 less than the number. Which of the following is the value of n?
Answer:
6
Step-by-step explanation: You can set up the equation: [tex]\sqrt{\frac{n}{3} }[/tex] = [tex]\sqrt{n-4}[/tex] You square both sides to cancel out the squares which leaves you with [tex]\frac{n}{3}[/tex] = n - 4. Then you just solve as normal which ends you up with an answer of 6. You can check this by plugging 6 back into the equation and see that you end up with [tex]\sqrt{2}[/tex] on both sides.

Hunter took out a $3500 loan with interest to pay for some business supplies. He will repay The loan and three years with monthly payments of $109.68. What is the total amount of interest hundred will pay? ( there's no answer choices)
Answer: $448.48
Step-by-step explanation:
The amount Hunter will pay in total is;
= 109.68 * 12 months * 3 years
= $3,948.48
Interest he will pay = Amount paid - Loan amount
= 3,948.48 - 3,500
= $448.48
