Check the picture below.

\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=2.9 \end{cases}\implies C=2\pi (2.9)\implies C=5.8\pi \implies C\approx 18.22 \\\\[-0.35em] ~\dotfill\\\\ ~\hfill \stackrel{C\div r}{18.22\div 2.9 \approx 6.28}\qquad \stackrel{C\div d}{18.22\div 5.8 \approx 3.14}~\hfill

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!<br><br> Which equation matches the graph?
tatyana61 [14]

Answer:  D) -2 |x| - 2

<u>Step-by-step explanation:</u>

A v-shaped graph is an absolute value graph.  

The general form of an absolute value equation is: y = a |x - h| + k

where (h, k) represents the vertex and "a" represents the vertical stretch (aka slope).  

The vertex of the given graph is (0, 2), however the graph is inverted (upside-down) which is a reflection across the x-axis.  Therefore,

  • a = -2
  • (h, k) = (0, -2)
<h2>                    --> y = -2 |x| - 2</h2>

X + y + 10 = 20 . If y = 2, find the value of x
podryga [215]

Answer:

x = 8

Step-by-step explanation:

x + y + 10 = 20

if y = 2,

=> x + 2 + 10 = 20

=> x + 12 = 20

=> x = 20 - 12

=> x = 8
