A sociologist recorded the estimated life expectancies of women born in Center City. Use the data from women born in 1970 and 20

00 to create a linear model that predicts the life expectancy, in years, (y) of a female born in a given year (x). . . Year Born Life Expectancy (years). 1960 66.1. 1970 67.6. 1980 70.1. 1990 71.9. 2000 74.0. 2010 75.9. . Which equation represents this linear model? a. y = 0.213x – 352.0 b. y = 0.213x – 358.4 c. y = 4.695x – 9181.6 d. y = 4.695x – 9322.4

Y = 0.213x – 352.0 <span> represents this linear model shown in the data table.
Plug in the values of x into the equation for a double check.
Let's try 1980.

</span><span>y = 0.213(1980) – 352.0
</span>y = 69.74
which is closest to the 70.1 whereas other options do not satisfy the condition.

Answer:

<u>Given is the piecewise function</u>

<h3>The first interval</h3>

<u>Domain:</u>

  • x ≤ -2

<u>The function</u>

  • y = 1
<h3>The second interval</h3>

<u>Domain</u>

  • -2 < x ≤ 0

<u>The function</u>

  • The slope is m = (0 - (-4))/(0 - (-2)) = 4/2 = 2
  • The y-intercept is 0
  • y = 2x
<h3>The third interval</h3>

<u>Domain</u>

  • x > 0

<u>The function</u>

  • The slope is m = (0 - 2)/(4 - 0) = - 1/2
  • The y-intercept is 2
  • y = -1/2x + 2

What is the solution to this ?
Advocard [28]

Answer:

\boxed{\sf C. \ x\geq -4}

Step-by-step explanation:

-8x+4\leq 36

\sf Subtract \ 4 \ from \ both \ sides.

-8x+4-4 \leq 36-4

-8x\leq 32

\sf Divide \ both \ sides \ by \ -8.

\frac{-8x}{-8} \leq \frac{32}{-8}

x\geq -4
