4x²-12x+9=5
4x²-12x+4=0

x= 12±√(144-4*4*4) / 2*4

x= 12 ± √(144-64) / 8

x=12±√80. /. 8

x= 12+4√5. /8

x=3±√5 / 2. C and E

I have three times as much money as does my brother. Our combined total is $42. How much does each of us have?
nika2105 [10]
For an instance, i stands for the money that you have, and b stands for the money that brother has.
An equation system based on the problem would be
i + b = 42 (equation 1)
i = 3b (equation 2)

Use substitution method to solve the problem
substitute 3b into i in the equation 1
i + b = 42
3b + b = 42
4b = 42
b = 42/4
b = 10.5

substitute the value of b into the equation 1
i = 3b
i = 3(10.5)
i = 31.5

You have $31.5 and your brother has $10.5

How do you use equations to solve problems about area of rectangles parallelograms trapezoids and rectangle.
julsineya [31]
Each shape has a different formula for area. rectangles and parallelograms share the same formula, A=bh
Trapezoids formula is A= 1/2(b1 + b2)h
Triangles formula is A = 1/2bh
In all of these formulas, A means area, and h means the height of the shape. In the formulas for triangles and rectangles/parallelograms, b stands for the length of the base of the shape. 
In the trapezoids formula, b1 means base 1 and b2 means base two, as a trapezoid has two different bases.
After finding all of the variables for the formula of the shape you're solving for, plug all the numbers into your missing variables, and solve as normal.

F(x)1/x please help me
koban [17]

Answer:

You are going to take the shape and flip if across the x Axis, reversing it essentially. then you will move it up 4, so of it is a square with one corner at (2,3) it will go to (5, 7) and all the other point will move together if I remember right. I last did this 3 years ago, I hope I help, next time show the whole graph with the number and I would have put a visual to show you the answer. Good luck
