Answer:

$ $74.37$

Step-by-step explanation:

To figure out how much is left in his checking account, simply subtract the amount he took out.

$124 -13.96 = 110.04$

$110.04 - 21.67 =88.37$

$88.37 - 14= 74.37$

$ $74.37$ is left in his checking account.

Fin find the slope of the line passing through the points (-2, -7) and (9, -7)

Verdich [7]

Answer:

The slope of the line passing through the given points (-2,-7) and (9,-7) is m=0

Step-by-step explanation:

Given that the line passing through the points (-2,-7) and (9,-7)

To find the slope of the line passing through the points :

$m=\frac{y_2-y_1}{x_2-x_1}$

Let $(x_1,y_1)$ and $(x_2,y_2)$ be the given points (-2,-7) and (9,-7) respectively

Substitute the points in the formula $m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{-7-(-7)}{9-(-2)}$

$=\frac{-7+7}{9+2}$

$=\frac{0}{11}$

Therefore m=0

Therefore Slope m is 0

Therefore the slope of the line passing through the given points (-2,-7) and (9,-7) is m=0

What is bigger 7/8 or 0.78

blsea [12.9K]

Solutions

To solve the problem we first have to convert the fraction into a decimal. To convert a fraction into a decimal you have to divide the numerator by the denominator.

7/8
= 7 ÷ 8
= 0.875

0.875 is bigger then 0.78 therefore 7/8 is greater.

What is the slope of a line perpendicular to the line whose equation is 2x+2y=28

malfutka [58]

Answer:

Step-by-step explanation:

1) First, place the given equation in slope-intercept form ( $y = mx +b$ format) to find its slope easier. Isolate the y:

$2x + 2y = 28\\2y = -2x + 28\\y = -x+14$

So, the equation of the line in slope-intercept form is $y = -x + 14$ . When an equation is in slope-intercept form, the $m$ , or the coefficient of the x-term, represents the slope. Thus, the slope for the given line would be -1.

2) Lines that are perpendicular have slopes that are opposite reciprocals of each other. We need to find the opposite reciprocal of -1, then.

To find the opposite reciprocal of a number, write the given number as a fraction first -- making -1 be written as $-\frac{1}{1}$ -- then switch the sign and flip the numerator and denominator. So, the opposite reciprocal of -1 is 1, and 1 is the slope of the perpendicular line.
