Answer:

y + 3 = -2(x - 4)

Step-by-step explanation:

(x₁,y₁) = (4 , -3)

(x₂,y₂) = (2 , 1)

[tex]Slope =\frac{y_{2}_y_{1}}{x_{2}-x_{1}}\\\\=\frac{1-[-3]}{2-4}\\\\=\frac{1+3}{-2}\\\\=\frac{4}{-2}\\\\= -2\\[/tex]

What is a quadratic equation?

A quadratic equation is an algebraic expression whose power is raised to the second degree. The solution of a quadratic equation usually leads to a pair of two factors.

From the given question, we are going to look for two numbers:

The result of the multiplication of these two numbers = (-5)The addition and subtraction of these two numbers = (-4)

Thus, the expansion of the quadratic equation will lead to the following factors:

Find the missing side. Round to the nearest 10th.

Answers

Answer:

5.0

Step-by-step explanation:

Using Pythagorean Theorem:

a² + b² = c²

where a =? b= 12 in and c = 13 in

a² + (12)² = (13)²

a² + 144 = 169

a² = 169 - 144

a² = 25

a = √25 = 5

∴ a = 5.0

Pythagoras Theorem is usually applied when finding one missing side of a right-angle triangle.

Step-by-step explanation:

when you plug in 0 for x, what your left with is the y intercept, the original and the second option both equal 12

Answer:

2,3&5

Step-by-step explanation:

y-intercept is the y-coordinates when x = 0,

Rewrite all the equations:

1. x² - 2x + 13

2. x² - 8x + 12

3. x² - 7x + 12

4. x² - 7x + 6

5. x² - 4x + 12

6. x² + 7x + 10

if the form of the quadratic equation is ax² + bx + c, c is the y-intercept of the function, thus 2,3&5 got the same y-intercept as the function f(x) = x² - 7x +12, which is 12.

Suppose that 6 people sitting in a enclosed room are each generating about 400 BTUs of body heat per hour. If the room is 20 ft × 15 ft × 10 ft, how many BTUs per cubic foot do they produce in 5 hours? A) 3 BTUs/ft3 B) 4 BTUs/ft3 C) 5 BTUs/ft3 D) 6 BTUs/ft3

Answers

Answer:  B) 4 BTUs/ft^3

Step-by-step:

For a cuboid of length L, width W and height H, the volume is:

V = L*W*H

In this case, we have:

L = 20ft

W = 15ft

H = 10ft

Then the volume of the room is:

V = 20ft*15ft*10ft = 3000 ft^3

Now we have 6 people, and each generate 400 BTUs per hour.

Then in total, they generate:

6*400 BTUs per hour

2400 BTUs per hour.

Now we want to find the BTUs per ft^3 produced in 5 hours.

Then if they generate 2400 BTUs per hour, in 5 hours they generate a total of:

5*2400 BTUs = 12000 BTUs

Now we take the quotient between the total BTUs and the volume of the room:

Q = (12000 BTUs)/(3000 ft^3) = 4 BTUs/ft^3

The correct option is B.
