Which equation has a graph of 7x=14y-8
masha68 [24]
You could re-write this to make it into an equation, you want to isolate the y, for a slope-intercept form. So you +8 to the other side; so it would be 7x+8=14y, then divide it by 14. And your equation would be y=4/7+x/2.

Which of the following is the graph of the rational function? y=x^2+2x-8/x^2-9
rusak2 [61]
Notice that we can simplify both numerator and denominator of our rational function. In the numerator we have a quadratic expression of the form ax^2+bx+c. To to simplify it, we are going to find tow numbers that add to 2 and multiply to -8; those numbers are 4 and -2.
x^2+2x-8=(x+4)(x-2)
In the denominator we have a difference of squares:
x^2-9=x^2-3^2=(x+3)(x-3)

Now we can rewrite our function:
y= \frac{x^2+2x-8}{x^2-9} = \frac{(x+4)(x-2)}{(x+3)(x-3)}

From the simplified form of our rational function we can infer that its graph has two vertical asymptotes at x=3 and x-3

We can conclude that the graphic of our rational function is:

Alchen [17]

I = C₀*i*t

I = 10.000*0,05*5

I = 2.500

C = C₀ + I

C = 10.000 + 2.500

C = 12.500

Solve for x: -5(2x-5)=8+(5-2x)<br><br> -4/3<br> -2<br> 3<br> 3/2
Nataliya [291]

Answer:

x =  \frac{17}{13}  = 1 \frac{4}{13}

Step-by-step explanation:

-5(2x - 5) = 8 + (5 - 2x)

-10x + 25 = 8 + 3x

-10x - 3x = 8 - 25

-13x = -17
