When the reciprocal of the larger of two consecutive even integers is subtracted from 4 times the reciprocal of the smaller, the

yawa3891 [41]

Answer: No solution

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

1st number: x

2nd number: x + 2

reciprocal of the larger is $\frac{1}{x+2}$

4 times the reciprocal of the smaller is 4 $(\frac{1}{x})$

reciprocal of the larger of two consecutive even integers is subtracted from 4 times the reciprocal of the smaller is 4 $(\frac{1}{x})$ - $\frac{1}{x+2}$

the result is 56: 4 $(\frac{1}{x})$ - $\frac{1}{x+2}$ = 56

Solve the equation:

4 $(\frac{1}{x})$ - $\frac{1}{x+2}$ = 56

$\frac{4(x(x + 2))}{x}$ - $\frac{1(x(x + 2))}{x+2}$ = 56(x(x + 2))

4x + 8 - x = 56x² + 112x

3x + 8 = 56x² + 112x

0 = 56x² + 109x - 8

Use the quadratic formula to solve:

x = $\frac{-109+/-11\sqrt{113}}{112}$

The result is NOT AN INTEGER so there is NO SOLUTION

The line plot shows the growth, In Inches, of Isabella's plant over 13 days. Growth of Isabella's Plant What is the total growth

mart [117]

Line plots are used to display data elements using markers

The total growth, in inches, of Isabella's plant is $4\frac{1}2$ inches

<h3>How to determine the total growth</h3>

From the line plot, the total growth can be represented as:

$Total = \frac 18 * 4 + \frac 28 * 2 + \frac 38 * 3 + \frac 48 * 1 + \frac 58 * 3$

Evaluate the products

$Total = \frac 48+ \frac 48 + \frac 98 + \frac 48 + \frac {15}8$

Evaluate the sum

$Total = \frac{4+4+9+4+15}8$

Evaluate the numerator

$Total = \frac{36}8$

Evaluate the quotient

$Total = 4\frac{1}2$

Hence, the total growth, in inches, of Isabella's plant is $4\frac{1}2$ inches
