3 0

Answer:

5n^2+(4n)-1

Step-by-step explanation:

(5n-1)(n+1)=0

Lets find <em>n.</em>

(5n-1)(n+1)=0

FOIL it.

5n^2+5n-1n-1

Add/Substract similar factors

5n^2+(5n-1n)-1

5n^2+(4n)-1

Thats your answer.

Given the point (10, 25) and m = 2.5 , write the equation for the function m(t) point-stope form.
dalvyx [7]

Answer:

the equation for the function m(t) point-stope form will be:

  • y - 25 = 2.5 (x - 10)

Hence, option D is correct.

The graph is attached below.

Step-by-step explanation:

Given

Point (10, 25)

Slope m = 2.5

To determine

Write the equation for the function m(t) point-stope form.

We know that the point-slope form of the line equation is

y-y_1=m\left(x-x_1\right)

where

  • m is the slope of the line
  • (x₁, y₁) is the point

In our case:

  • m = 2.5
  • (x₁, y₁) = (10, 25)

so

substituting the values m = 2.5 and the point (10, 25) in the equation

y-y_1=m\left(x-x_1\right)

y - 25 = 2.5 (x - 10)

Therefore, the equation for the function m(t) point-stope form will be:

  • y - 25 = 2.5 (x - 10)

Hence, option D is correct.

The graph is attached below.

In obtuse triangle ABC, mA = 104 and mC = 32. Find mB.
Margaret [11]
If I’m right a triangle = 180, so 104+32 = 136. Now 180-136=44 if it’s not a answer just redo my math because at the moment I have no paper.

The variable y is directly proportional to the variable x. If y = 12 when x = 14, what is the value of x when y = 24? A) 26 B) 2
vekshin1

Hi There!

Answer:

B) 28

Step-by-step explanation:

y = 12 and x = 14 are both proportional.

y = 24 and x = ? are both proportional.

You notice that 24 is twice as much as 12 so we do the same with x.

14 * 2 = 28

They are both proportional when y = 24 and x = 28.

Hope This Helps :)
