Answer:

Yes because the answer to both of them is 1

Step-by-step explanation:

Let's solve your equation step-by-step.

−2x+9=7

Step 1: Subtract 9 from both sides.

−2x+9−9=7−9

−2x=−2

Step 2: Divide both sides by -2.

−2x

−2

=

−2

−2

x=1

Answer:

x=1    

Let's solve your equation step-by-step.

2x=2

Step 1: Divide both sides by 2.

2x

2

=

2

If the Volume of a box is 250 feet3 and the height is 5 feet and the length is 5
Montano1993 [528]

Answer:

10 feet

Step-by-step explanation:

Use the volume formula, V = lwh, to solve for w

Plug in the values we know:

V = lwh

250 = (5)(w)(5)

250 = 25w

10 = w

So, the width is 10 feet

2. Decide which estimate is closest to the actual answer. Explain your reasoning.
sashaice [31]
Question A 
take $100.80 divide it by 35 which would equal 2.88 
so round that up for 3.0 for the closest answer

Question B 
take 49.2 and divide it by 6 which would equal 8.2
so round it to the nearest number which would be 8.0

Question C
take 0.78 and divide it by 20L which would equal 0.039
so round that up to the closest number which would be 0.04L

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
