|-9x-4|=77 Can you show all of your too please
Korvikt [17]
<span>9x + -4 = 77 Reorder the terms: -4 + 9x = 77 Solving -4 + 9x = 77 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + 9x = 77 + 4 Combine like terms: -4 + 4 = 0 0 + 9x = 77 + 4 9x = 77 + 4 Combine like terms: 77 + 4 = 81 9x = 81 Divide each side by '9'. x = 9 Simplifying x = -9</span>

1. A 15 feet tree casts a shadow that is 8 feet long. What is the distance from the tip of the tree to the tip of its
natka813 [3]

Answer:

the answer is 17 feet

Step-by-step explanation:

you have to use the pythagorean theorem.

a^{2} + b^{2} = c^{2}

for a is 15 and b is 8

15^{2} + 8^{2} = 289

289 = c\^{2}

\sqrt{289} = 17

therefore, the distance is 17 feet.

Cost, Revenue, and Profit A company invests $98,000 for equipment to produce a new product. Each unit of the product costs $12.2
Vesnalui [34]

Given:

Investment on equipment = $98,000

Cost of each unit = $12.20

Selling price of each unit = $16.98.

To find:

(a) The total cost C as a function of x.

(b) The revenue R as a function of x.

(c) The profit P as a function of x.

Solution:

Let x be the number of units produced and sold.

We have,

Fixed cost = $98,000

Variable cost = $12.20x

Total cost = Fixed cost + Variable cost

C(x)=98000+12.20x

Therefore, the cost function is C(x)=98000+12.20x.

Selling price of each unit = Revenue from each unit =  $16.98.

Total revenue = Revenue from x units

R(x)=16.98x

Therefore, the revenue function is R(x)=16.98x.

Profit = Revenue - Cost

P(x)=R(x)-C(x)

P(x)=16.98x-(98000+12.20x)

P(x)=16.98x-98000-12.20x

P(x)=4.78x-98000

Therefore, the profit function is P(x)=4.78x-98000.

What is the slope of (12,-18) and (11,12)? Please I’m very confused.
Lesechka [4]

Answer:

-30

Step-by-step explanation:

\boxed{slope =  \frac{y1 - y2}{x1 - x2} }

where (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.

Slope

=  \frac{12 - ( - 18)}{11 - 12}

=  \frac{12 + 18}{ - 1}

= -30
