What is the coefficient of the variable in the expression 6-4x-8x+2

Mathematics
1 answer:
Daniel [21]3 years ago
6 0

I think the trick is to add the two middle terms together.  (And the 2 end terms).

8 - 12x

The variable is x. The coefficient is - 12.

8 is a constant.

The coefficient always goes with a variable.

3x^2 + 2x + 5

Nothing can be combined.  The leading coefficient is 3 (which goes with the greatest power of the variable x^2 in this case) and the other coefficient is 2. 5 is a constant.

Write an equation of a line that passes through point (5, 3) and is perpendicular to the line 2y = 5x – 8.
anastassius [24]

Answer:

y= -2/5+5

Step-by-step explanation:

A line must always be written in the form y= and the line given is not. Dividing both sides of the equation by 2 you get y=5/2x-4. This is the equation of the line given.

Perpendicular line have gradients that, when they are multiplied, they are equal to -1

The line given multiplied by the gradient of the line(the one required to find)= - 1. That is 5/2×line= -1.

Dividing both sides of the equation by 5/2 you'll get - 2/5. This is the gradient of the line required.

Using the general formula y=mx+c substitute the gradient into the equation. You'll get something like this y= -2/5x+c.

Substitute the given point into the equation. You'll get something like this 3= -2/5(5)+c.

Calculate the value of c. You'll get c=5.

Substitute the value of c into the original equation. You'll get something like this y= -2/5+5

This is the equation: y= -2/5+5
