PLEASE HELP MEEE which ordered pair is a solution to this equation -3x-7y=8

Find the slope of the line passing through (3, 7) and (6, 11). Note: Use the y-y/x-x formula!

lana [24]

Answer:

Slope of the line $m = \frac{4}{3}$

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given points are ( 3,7) and (6,11)

Slope of the line

$m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

$m = \frac{11-7}{6-3}$

$m = \frac{4}{3}$

Slope of the line $m = \frac{4}{3}$

If CF = 5, CD = 12, and EF = 5, what is the perimeter of triangle CDE?

Basile [38]

Answer:

The perimeter of triangle CDE is 34.

Step-by-step explanation:

To find the perimeter of a triangle, you have to add all the sides together, since this looks like a isosceles triangle, you would make side ED also 12 and then just add them all together.

12+12+5+5= 34.

Answer ASAP! Forty rabbits are introduced onto a small uninhabited island. They have no predators, and food is plentiful on the

Alex73 [517]

Answer:

4 years

Step-by-step explanation:

Forty rabbits , increasing by 50% each year

first year : 40+(40*50%)= 60 rabbits

second year: 60+(60*50%)=90

third year : 90+(90*50%)=135

fourth year: 135+(135*50%)= 202.5 ≅ 203 rabits

after 4 years

40(1+0.5)^4= 202.5 ( almost 200)

21. Water that is sprayed upward from a

sleet_krkn [62]

Answer:

2 seconds to maximum height
20 meters maximum height
4 seconds to reach the ground

Step-by-step explanation:

The function can be graphed using a graphing calculator, geometry app, or spreadsheet. One such graph is attached. Often, these tools are capable of identifying extrema and intercepts.

__

<h3>extreme</h3>

The vertex of the graph is reported as (x, y) = (2, 20). This means the maximum height is reached after 2 seconds. That maximum height is 20 meters.

__

<h3>intercept</h3>

The drop is launched from ground level at x = 0 seconds. It returns to ground level at x = 4 seconds.

A manufacturer of widgets finds that the production cost, C, in dollars per unit is a function of the number of widgets produced

Elis [28]

Answer:

I guess that you want to find the profit:

We have two equations:

the cost equation:

C(x) = -0.1*x^2 + 100.

And the selling equation, that is a vertical stretch of the cost equation by a factor of 1.4:

S(x) = 1.4*C(x) = 1.4*( -0.1*x^2 + 100.) = -0.14*x^2 + 140

Now, whit those two equations we can find the profit equation, that is defined as the difference between the selling price, and the cost:

P(x) = S(x) - C(x) = 1.4*C(x) - C(x) = (1.4 - 1)*C(x) = 0.4*C(x).

Then the profit is 0.4 times the initial cost.

P(x) = 0.4*( -0.1*x^2 + 100.) = -0.04*x^2 + 40
