Im having trouble on 2 questions... 2 (x-5)=x-8 and 2 (x-5)=x.... can u figure them out and explain how to get them.... thanks

Answers

Answer 1

Answer: $2(x-5)=x-8\n2x-10=x-8\n2x-x=-8+10\nx=2\n\n2(x-5)=x\n2x-10=x\n2x-x=10\nx=10$

What is the fuction eqation for (0,-2)and (5,-1)

Answers

y = mx + b

m is the slope
b is the y-intercept

First find the slope

$slope = (y_2-y_1)/(x_2-x_1) = (-1+2)/(5-0)= (1)/(5)$

So far we have: y = 1/5x + b

Now we need to find b

y = 1/5x + b

Plug in (0,-2)

-2 = 1/5(0) + b

-2 = b

So the final equation is $\boxed{y=(1)/(5)x-2}$

f(x) = 1/5 x - 2

-2 is your y intercept and using (y-y)/(x-x) you can get slope

(-1 - - 2)/ (5-0) = (-1+2) / (5) = 1/5

Explain why graphs show the first quadrant but omit the other three quadrants.

Answers

It is because the first quadrants have positive values of x and y.

What are quadrants?

Quadrants are one-fourth of coordinate geometry and it is counted in an anticlockwise direction from the right top.

The angle of any quadrant is 90 degrees.

The only quadrant in which x and y both are positive is the first quadrant.

If we draw any figure in the first quadrants then it becomes easy to do any operation because of the positive values of x and y.

For example, if you want to measure distance then in the first quadrant it si positive but in the second or any other either x or y or both will be negative.

Hence "It is because the first quadrants have positive values of x and y".

It's because if you are only working with positives, then the first quadrant is the only one that can help you, if you draw the other 3, then you just take up too much space to represent something you don't even need to show
