1 day =1/6m

d = 8 m

the equation to set up is

1/6d=8 solve for the number of days

1/6d×6=8×6

d=48

A horizontal line goes through the point (–7,10). Which statements are true about this line? Check all that apply.

Nata [24]

The slope of the line is the change in y values over the change in x values, since for horizontal line, the y values do not change then, the slope is zero.

If the line is horizontal, this means that whatever the value of the x-coordinate (abscissa) is, the y-coordinate (ordinate) will always be 10.

The intercept of the line is 10. So, third statement is not true.

Since the equation of the line is zero and its y-intercept is zero, using the equation of the line which is,
y = mx + b
where m is slope and b is y-intercept. The equation of the line is,
y = 0x + 10 ; y = 10

<em>The true statements for this item are 1st, 2nd, and 4th.</em>

What is the roots of f(x)=-x^2-6x-14

Nutka1998 [239]

Answer:

$x=-3\pm i \sqrt{5}$

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS
Equality Properties

<u>Algebra I</u>

Standard Form: ax² + bx + c = 0
Quadratic Formula: $x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

<u>Algebra II</u>

Imaginary roots: √-1 = i

Step-by-step explanation:

<u>Step 1: Define function</u>

f(x) = -x² - 6x - 14

<u>Step 2: Set up</u>

Set equation equal to 0: -x² - 6x - 14 = 0
Factor out -1: -(x² + 6x + 14) = 0
Divide both sides by -1: x² + 6x + 14 = 0

<u>Step 3: Define variables</u>

a = 1

b = 6

c = 14

<u>Step 4: Find roots</u>

Substitute: $x=\frac{-6\pm\sqrt{6^2-4(1)(14)} }{2(1)}$
Exponents: $x=\frac{-6\pm\sqrt{36-4(1)(14)} }{2(1)}$
Multiply: $x=\frac{-6\pm\sqrt{36-56} }{2}$
Subtract: $x=\frac{-6\pm\sqrt{-20} }{2}$
Factor: $x=\frac{-6\pm\sqrt{-1} \sqrt{20} }{2}$
Simplify: $x=\frac{-6\pm2i \sqrt{5} }{2}$
Factor: $x=\frac{2(-3\pm i \sqrt{5} )}{2}$
Divide: $x=-3\pm i \sqrt{5}$

(25 POINTS AND BRAINLIEST FOR BEST)

grandymaker [24]

I'll make it up to you

A. Define the variables and write an equation to represent the relationship between the price of a home and the commission received.

Commission are a form of variable-pay remuneration for services rendered or products sold.

Equation would be like this (with s for sale of a house and c for commission),

5% of s = C

B. How much commission will the realtor earn for selling a $150,000 home?

Use equation.

5% of 150,000 = C

5% of 150,000 = $7,500

C. If the realtor earned an $8750 commission, what was the price of the home? $175,000

I forgot how to explain it to you but this is the answer.
