What is the Slope of 7x+4y=20

Mathematics
1 answer:
yKpoI14uk [10]3 years ago
8 0

<u><em>Answer:</em></u>

slope = \frac{-7}{4}


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

<u>The general form of the linear line is:</u>

y = mx + c

where:

m is the slope

c is the y-intercept


<u>The given equation is:</u>

7x + 4y = 20


<u>We will start by putting the equation in the general form:</u>

7x + 4y = 20

4y = -7x + 20

\frac{4y}{4} = \frac{-7x}{4} + \frac{20}{4}

y = \frac{-7}{4} x + 5


<u>Now, comparing our equation with the general form, we would find that:</u>

m = slope = \frac{-7}{4}

c = y-intercept = 5


Hope this helps :)

What is the equation of a line passing through (5,2) and parallel to the line represented by the equation y - 2x + 1?
34kurt

Step-by-step explanation:

Im not sure if its supposed y = -2x + 1 or y = 2x + 1 but I'll solve the problem for both.

First for y = -2x + 1

Since the line has to be parallel to y = -2x + 1

the slopes would be the same.

so, so far the equation would be

y = -2x + b

now we substitute (5,2) into the equation

2 = -2(5) + b

2 = -10 + b (Add 10 to both sides of the equation)

+10 +10

12 = b

Now that we solved for b

The equation would be

y = -2x + 12

^^ This equation is parallel to y = -2x + 1

Now to solve for an equation parallel to y = 2x + 1

Both equations would have the same slope

So far we would have

y = 2x + b

Now we solve for be by substituting the point (5,2)

2 = 2(5) + b

2 = 10 + b (subtract 10 from both sides)

-10 -10

-8 = b

After solving for b

The equation is

y = 2x - 8

This equation is parallel to y = 2x + 1

compute the mean and variance of the following discrete probability distribution. (round your answers to 2 decimal places.) x p(
a_sh-v [17]

The  determined value of mean µ is 1.3 and variance σ² is 0.81.

What is mean and variance?

  • A measurement of central dispersion is the mean and variance. The average of a group of numbers is known as the mean.
  • The variance is calculated as the square root of the variance.
  • We can determine how the data we are collecting for observation are dispersed and distributed by looking at central dispersion.

The table is attached as an image for reference.

Mean µ = ∑X P(X)

         µ = 1.3

Variance (σ² ) = ∑ X² P(X)- (µ)²

                       = 2.5-(1.3)²

                (σ² ) = 0.81

The  determined value of mean µ is 1.3 and variance σ² is 0.81.

12 cos theta minus 16 sin theta is equal to zero find 2 sin theta + cos theta​
gayaneshka [121]

Answer:

2sinθ + cosθ = 2

Step-by-step explanation:

12 cos θ - 16 sinθ = 0

=> 3 cos θ -4 sin θ = 0

=> tanθ = 3/4

let P = 3x

B = 4x

=> H= 5x

=> sinθ = P/H = 3/5

cosθ = B/H = 4/5

2sinθ + cosθ

= 2× 3/5 + 4/5

= 6/5+4/5

= 10/5

= 2

=> 2sinθ + cosθ = 2
