Solve for x: x^2+4x-5=16x
first take 16x from both sides of the equation
x²-12x-5=0
now we have a quadratic. we can solve it by using the quadratic formula
x=-b plus or minus the square root of b²-4ac all divided by 2a
where a=1, b=-12 and c=-5
plug these numbers into the formula
x=12 plus or minus the square root of 144-4x1x-5 all divided by 2
<span>x=12 plus or minus the square root of 164 all divided by 2
or in decimal form </span>x = {12.403124237, -0.403124237}
Answer:
B. It makes the graph really narrow.
Step-by-step explanation:
![\displaystyle Y = A[X - H]^2 + K](https://tex.z-dn.net/?f=%5Cdisplaystyle%20Y%20%3D%20A%5BX%20-%20H%5D%5E2%20%2B%20K)
In the Vertex Formula, any <em>fraction</em><em> </em>you store in for <em>A</em><em> </em>will result in a <u>vertical</u><u> </u><u>shrink</u>, widening the graph, whereas any <em>whole number</em> you store in for <em>A</em> will result in a <u>vertical stretch</u>, narrowing the graph.
