I am having trouble<br> 2(10-13x)=-34x+60
morpeh [17]
<span>Simplifying 2(10 + -13x) = -34x + 60
(10 * 2 + -13x * 2) = -34x + 60
(20 + -26x) = -34x + 60
 Reorder the terms: 20 + -26x = 60 + -34x
 Solving 20 + -26x = 60 + -34x
 Solving for variable 'x'.
 Move all terms containing x to the left, all other terms to the right.
 Add '34x' to each side of the equation. 20 + -26x + 34x = 60 + -34x + 34x
 Combine like terms: -26x + 34x = 8x 20 + 8x = 60 + -34x + 34x
 Combine like terms: -34x + 34x = 0 20 + 8x = 60 + 0 20 + 8x = 60
Add '-20' to each side of the equation. 20 + -20 + 8x = 60 + -20
 Combine like terms: 20 + -20 = 0 0 + 8x = 60 + -20 8x = 60 + -20
 Combine like terms: 60 + -20 = 40 8x = 40
 Divide each side by '8'. x = 5
 Simplifying x = 5</span>

Use the graph of f(x) below to estimate the value of f '(3):
klio [65]
Well, looking at the graph, notice, its vertex is at 0,9, and it passes through the points -3,0 and 3,0, so hmm let's use 3,0, to get the equation of f(x)

\bf ~~~~~~\textit{parabola vertex form}&#10;\\\\&#10;\begin{array}{llll}&#10;\boxed{y=a(x- h)^2+ k}\\\\&#10;x=a(y- k)^2+ h&#10;\end{array}&#10;\qquad\qquad&#10;vertex~~(\stackrel{}{ h},\stackrel{}{ k})\\\\&#10;-------------------------------

\bf vertex~(0,9)~&#10;\begin{cases}&#10;h=0\\&#10;k=9&#10;\end{cases}\implies y=a(x-0)^2+9&#10;\\\\\\&#10;\textit{we also know that }&#10;\begin{cases}&#10;x=3\\&#10;y=0&#10;\end{cases}\implies 0=a(3-0)^2+9&#10;\\\\\\&#10;-9=9a\implies \cfrac{-9}{9}=a\implies -1=a\quad thus\quad \boxed{y=-x^2+9}&#10;\\\\\\&#10;\left. \cfrac{dy}{dx}=-2x \right|_{x=3}\implies -6

Determine the number of solutions that exist to the equation. 8(j-4)=2(4j-16)
lukranit [14]
<span>8(j-4)=2(4j-16)
8j - 32 = 8j - 32

Since both sides are equal, there are is an infinite number of solutions.
