David can read 50 pages in 50 minutes.
(50 pages)/(50 minutes) = 1 page/minute
Since David reads 1 page per minute,
in 80 minutes David can read 80 pages.
Answer:
So slope 1 would be positive
Slope 2 would be negative
Slope 3 would be zero
Step-by-step explanation:
If the slope is moving up from left to right, then it is positive
If the slope is moving down from left to right, then it is negative
If the slope is a vertical line and is not moving left/right, then it is undefined
If the slope is a horizontal line and is not moving up/down, then it is zero
So slope 1 would be positive because it is moving up from left to right.
Slope 2 would be negative because it is moving down from left to right.
Slope 3 would be zero because it is a horizontal line that is not moving up or down.
Hope this helped!
Answer:
x=2
Step-by-step explanation:
use distributive property: x^2+2x-1=4
remove the -1 by adding 1 on both sides: x^2+2x=5
use the guadratic fromula: ax²+bx+c=0
plug in the equation x^2+2x-5=0
a,b and c are the coefficients to plug into the formula
a=1, b=2, c=-1
Finally, you will find that x=2
