B

You would catch more trout because of the percentage but you will most likely catch at least 1 bass.

Answer:

B

1:4

Step-by-step explanation:

If it 20%:80% that means its 1:4 because 20% of five is 1 and 80% of five is 4

How do i completely factor 9c^4-36c^2?
VLD [36.1K]
You take out the biggest factor of 9 and 36 which is 9c^2. The factors both have the c variable in common so you take the least exponent and put it with the gcf.

9c^2(c^2+4)

What is the solution to this system of linear equations? x − 3y = −2 x + 3y = 16
Oksana_A [137]
To solve for the solution of this system of linear equation, it is best to use substitution. From the first equation, x = 3y

Substituting the expression on the right for the value of x on the second equation, 
 
                                    -2(3y) + 3y = 16

Solving for the value of y gives y = -5 1/3

With this value of y, solving for x gives x = -16

Thus, the solution for this system of linear equation is (-16, -5 1/3)

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and c the y- intercept )

(1)

Here m = 6 and b = - 2, then

y = 6x - 2

(2)

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Here m = - 2 and b = 5, then

y = - 2x + 5 ← equation in slope- intercept form

Add 2x to both sides

2x + y = 5 ← equation in standard form

(3)

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (6, - 13) and (x₂, y₂ ) = (- 4, - 3)

m = \frac{-3+13}{-4-6} = \frac{10}{-10} = - 1 , then

y = - x + b ← is the partial equation

To find b substitute either of the 2 points into the partial equation

Using (- 4, - 3 ) , then

- 3 = 4 + b ⇒ b = - 3 - 4 = - 7

y = - x - 7 ← equation in slope- intercept form

Add x to both sides

x + y = - 7 ← equation in standard form
