Answer:

slope = -4

Step-by-step explanation:

(y - y1)/(x -x1)

= ( 0 -8)/(5-3)

= -4

Answer:

-4

Step-by-step explanation:

Slope = \frac{y_{2} - y_1 }{x_2-x_1}

Let (3,8) be (x_{2},y_2 ) and (5,0) be (x_1,y_1)

Now we can solve using the slope formula!

\frac{8-0}{3-5} = \frac{8}{-2} = -4

The slope is -4

Hope this helps :)

Have a great day!

Alekssandra [29.7K]

Answer:

174879 units

Step-by-step explanation:

Given that The Elmina Wilson Company produces spaghetti sauce.

Fixed costs =1,329,050 $

Selling price per  64 oz=12.40

Variable cost per can   = 4.80

Contribution = S-V=Selling price - var cost = 7.60 $

Break even poin in no of units = Fixed cost/Contribution per unit

=\frac{1,39,050}{7.60} \\=174878.94\\=174879

What is the equation of the directrix of the parabola given by the equation (y − 3)2 = 8(x − 5)?
Licemer1 [7]
The vertex of the parabola is at (5,3) and its focal length is 8/4 = 2.
Since it opens to the right, the directrix will be a vertical line 2 units to the left of the vertex, so its equation will be x=(5-2), or x=3

svlad2 [7]

Answer:

Dimensions of the rectangular plot will be 500 ft by 750 ft.

Step-by-step explanation:

Let the length of the rectangular plot = x ft.

and the width of the plot = y ft.

Cost to fence the length at the cost $3.00 per feet = 3x

Cost to fence the width of the cost $2.00 per feet = 2y

Total cost to fence all sides of rectangular plot = 2(3x + 2y)

2(3x + 2y) = 6,000

3x + 2y = 3,000 ----------(1)

3x + 2y = 3000

      2y = 3000 - 3x

      y = \frac{1}{2}[3000-3x]

      y = 1500 - \frac{3x}{2}

Now area of the rectangle A = xy square feet

A = x[1500-\frac{3x}{2}]

For maximum area \frac{dA}{dx}=0

A' = \frac{d}{dx}(1500x-\frac{3}{2}x^{2}) = 0

1500 - 3x = 0

3x = 1500

x = 500 ft

From equation (1),

y = 1500 - \frac{3}{2}\times 500

y = 1500 - 750

y = 750 ft

Therefore, for the maximum area of the rectangular plot will be 500 ft × 750 ft.

two fencing 3(500+500) = $3000

other two fencing 2(750+750) = $3000

11. Write the equation in slope intercept form that has a slope of -23 and passes through the point (-1, 2).
insens350 [35]
11. y = -23x - 21

You can get this by starting with y = mx + b (slope intercept form). Then put in all the knowns and solve for the b. 

2 = -23(-1) + b
2 = 23 + b
-21 = b

Then add that to the end of the equation with m = -23

12. -5

The y-intercept of an equation is always the number added on at the end of an equation. It is also the number with no x attached to it. 

13. 8x^9y^6

When you use the law of exponents, you need to make sure the exponent goes to each individual term. When we cube the 2, it becomes 8. When you cube x^3, you get x^3*x^3*x^3 or x^9. And with y^2 you get y^6
