AC=8x-14 and EC=2x+11, solve for x
dimaraw [331]

Answer:

x = 4.167

Step-by-step explanation:

8x - 14 = 2x + 11 add 14 to 14

8x = 2x + 25 subtract 2x to 2x and 8x

6x = 25 divide by 6

x= 4.167 repeating

What is the equation of the quadratic function represented by this table?
MA_775_DIABLO [31]

Answer:

Step-by-step explanation:

I used logic and took the easy way around this as opposed to the long, drawn-out algebraic way.  I noticed right off that at x = -3 and x = -1 the y values were the same.  In the middle of those two x-values is -2, which is the vertex of the parabola with coordinates (-2, 4).  That's the h and k in the formula I'm going to use.  Then I picked a point from the table to use as my x and y in the formula I'm going to use.  I chose (0, 3) because it's easy.  The formula for a quadratic is

y=a(x-h)^2+k

and I have everything I need to solve for a.  Filling in my h, k, x, and y:

3=a(0-(-2))^2+4  and

3=a(2)^2+4  and

-1 = 4a so

a=-\frac{1}{4}

In work/vertex form the equation for the quadratic is

y=-\frac{1}{4}(x+2)^2+4

In standard form it's:

y=-\frac{1}{4}x^2-x+3

How to solve this???<br> e^(2x) - e^x = 6
Ray Of Light [21]
e^{2x}-e^x=6
(e^x)^2-e^x-6=0
(e^x-3)(e^x+2)=0

e^x=3
e^x=-2

therefore x=\ln3 and x=\ln-2
because \ln-2 doesn't exist, the only solution to your equation is x=\ln3
