Answer:

[tex]y = -9x +52[/tex]

Step-by-step explanation:

Given

[tex](x_1.y_1) = (5,7)\\[/tex]

[tex](x_2,y_2) = (6,-2)[/tex]

Required

Determine the equation in slope intercept form

First, we calculate the slope of the line:

[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]

This gives:

[tex]m = \frac{7 - (-2)}{5 - 6}[/tex]

[tex]m = \frac{7 +2}{-1}[/tex]

[tex]m = \frac{9}{-1}[/tex]

[tex]m = -9[/tex]

Th equation is then calculated using:

[tex]y - y_1 = m(x - x_1)[/tex]

This gives:

[tex]y - 7 = -9(x - 5)[/tex]

Open bracket

[tex]y - 7 = -9x +45[/tex]

Make y the subject

[tex]y = -9x +45+7[/tex]

[tex]y = -9x +52[/tex]

Answer:

The widgets should be sold for $26.7 for the company to make the maximum profit.

Step-by-step explanation:

Given the quadratic equation

[tex]f\left(x\right)=-15x^2+801x-59000[/tex]

As the leading coefficient is (-3), so the graph would be a downward Parabola.

Thus, the maximum profit would be at the vertex.

The selling price 'x' can be determined by determining the x-coordinate of the vertex.

In order to calculate the x-coordinate of the vertex, we can find this by

x = -b/2a

where a = -15 and b = 801

x = -801 / 2(-15)

x = -801/-30

x = 801/30

x = 267/10

x = 26.7

Therefore, the widgets should be sold for $26.7 for the company to make the maximum profit.

                                                               |               |

                                                               5              5

The prime factorization of 100 is 2 * 2 * 5 * 5, or 2^2 * 5^2, or 5^2 * 2^2

Step-by-step explanation:

2^2 × 5^2 =

(2×2) × (5×5) =

4 × 25 = 100

5^2 × 2^2 =

(5×5) × (2×2) =

25 × 4 = 100

2*2*5*5=100

2 and 5 are the only prime numbers in this question. 2(2)*5(5) doesnt equal 100.

Answer:

It will take 1.6 hours for the two trains to be 336 miles apart.

Step by step explanation:

Given that:

Speed of eastbound train = 95 miles per hour

Speed of westbound train = 115 miles per hour

Combined speed = 95+115 = 210 miles

Distance = 336 miles

[tex]Speed = \frac{Distance}{Time}\\\\210 = \frac{336}{Time}\\\\Time = \frac{336}{210}\\\\Time = 1.6\ hours[/tex]

Hence,

It will take 1.6 hours for the two trains to be 336 miles apart.

Answer:

-7 =k

Step-by-step explanation:

y = 3x + k

Substitute 3 in for x and 2 in for y

2 = 3*3+k

2 = 9+k

Subtract 9 from each side

2-9 = k

-7 =k

Answer:

5 portions of porridge requires

250g of oats, 0.75L of milk and 25g of sugar

Step-by-step explanation:

This recipe makes 8 portions of porridge. Complete the amount of each ingredient that is needed to make just 5 portions.

The ingredients for the recipe = Oats, Milk, Sugar

Hence:

For Oats

8 portions of porridge = 400g of oats

5 portions of porridge = x

Cross Multiply

8x = 5 × 400

x = 5 × 400/8

x = 250g of oats

For Milk

8 portions of porridge = 1.2 L of milk

5 portions of porridge = x

Cross Multiply

8x = 5 × 1.2

x = 5 × 1.2/8

x = 0.75 L of milk

For sugar

8 portions of porridge = 40g of sugar

5 portions of porridge = x

Cross Multiply

8x = 5 × 40

x = 5 × 40/8

x = 25g of sugar

Hence:

5 portions of porridge requires

250g of oats, 0.75L of milk and 25g of sugar

Answer:

76

Step-by-step explanation:

Plug 4 in for each x

Answer:

76

Step-by-step explanation:

given f(x)=x^3+x^2-x what is f(4)

whenever u see f(4) it is telling you that whenever you see an x you would replace it with a 4  so you start substituting the x for 4's or replacing them (same thing XD) 4^3+4^2-4  4 times 4 times 4 = 64 + 4 times 4 = 16

64 + 16 - 4 = 76

Answer:

see in this picture, the point of Lake House is (-2;5)

                               the point of Cabin is (6;3)

                               the point of Store is (-4;-5)

=> the distance between Lake House to Store is [tex]\sqrt{(-4-(-2))^{2}+(-5-5)^{2} }=2\sqrt{26}[/tex]

the distance between Cabin to Store is [tex]\sqrt{(-4-6)^{2}+(-5-3)^{2} }=2\sqrt{41}[/tex]

Step-by-step explanation:

Answer:

Kerri's speed = 50 mile per hour. Therefore option (D) is true.

Step-by-step explanation:

Given the distance-time graph

It is clear from the distance-time graph that:

so the two points on the distance-time graph is:

Finding the slope between the points to determine the speed.

Please note that the slope between the points represents the speed or rate of change.

Speed = Rate of change = y₂-y₁ / x₂-x₁

                                         = 100 - 50 / 2-1

                                          = 50 / 1

                                           = 50 miles per hour

Thus, Kerri's speed = 50 mile per hour. Therefore option (D) is true.

Here is the complete question:

suppose m is the line with equation x=-5, line n is the line with equation y=1, line g is the line with equation y=x, and line h is the line with equation y=-2. Given A(9,-3), B(6,4), and C(-1,-5), what are the coordinates of the vertices of △A′B′C′ for each reflection?

1. Rx-axis

2. Ry-axis

Answer with step-by-step explanation:

1. When you get the reflecting coordinates along x-axis, the signs of the y coordinates changes. Therefore, A(9,-3), B(6,4), and C(-1,-5) becomes:

A(9, 3), B(6, -4), and C(-1, 5).

2. When you get the reflecting coordinates along y-axis, the signs of the x coordinates changes. Therefore, A(9,-3), B(6,4), and C(-1,-5) becomes:

A(-9, -3), B(-6, 4), and C(1, -5).
