(19 + 28 + 62 + 51 + x) / 5 = 38
(160 + x) / 5 = 38
160 + x = 38 * 5
160 + x = 190
x = 190 - 160
x = 30 <== age of 5th person

What is the equation of the line that passes through the point (6,-6) and is parallel to the x axis
Rzqust [24]

Answer:

y=-6

Step-by-step explanation:

we know that

A line parallel to the x-axis is a horizontal line

The equation of a horizontal line is equal to the y-coordinate of the point that passes through it

In this problem the line passes through the point (6,-6)

so

The y-coordinate is -6

therefore

The equation of the line is

y=-6

Vera_Pavlovna [14]

Answer:

Jack's final bank account amount will be $54,782.50, <em>earning</em> <u>$7,459.31</u> in <em>interest</em>.

General Formulas and Concepts:
<u>Algebra I</u>

Compounded Interest Rate Formula: \displaystyle A = P \bigg( 1 + \frac{r}{n} \bigg) ^{nt}

  • <em>A</em> is final amount
  • <em>P</em> is principle amount
  • <em>r</em> is rate
  • <em>n</em> is compounded rate
  • <em>t</em> is time

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify given variables</em>.

<em>P</em> = $47,323.15

<em>r</em> = 0.05

<em>n</em> = 1

<em>t</em> = 3

<u>Step 2: Find Interest</u>

  1. [Compounded Interest Rate Formula] Substitute in variables:
    \displaystyle A = 47323.15 \bigg( 1 + \frac{0.05}{1} \bigg) ^{1(3)}
  2. Evaluate:
    \displaystyle A = \boxed{54782.5}

∴ Jack will <em>gain</em> $7,459.31 and have a net balance of $54,782.50.

If f(x) = x² + 1 for what x value is f(x) = 2?
MaRussiya [10]

Answer:

x = ±1

Step-by-step explanation:

Step 1: Define variables

f(x) = x² + 1

f(x) = 2

Step 2: Substitute

2 = x² + 1

Step 3: Solve for <em>x</em>

0 = x² - 1

0 = (x - 1)(x + 1)

x - 1 = 0

x = 1

x + 1 = 0

x = -1

∴ x = ±1
