Let "a" and "b" be the two numbers
So a*b=-8 and a+b=-7
Therefore S=-7 and P=-8
Using (x^2)-S+P=0 => (x^2)-(-7)+(-8)=0 => (x^2)+7-8=0
By factorizing we get (x+8)(x-1)=0
So a can be either -8 or 1 and b can be 1 or -8
Meaning that the two numbers are -8 and 1.

Step-by-step explanation:
Given :
Length of the rectangle (l)=15m
Width of the rectangle (w)= 6 m
Area of the rectangle can be calculated as :
Now,
Side of square (s)=12 m
Area of the square can be find:
Answer:
C
Step-by-step explanation:
Graph C has a negative slope, just like the equation, and the y-intercept is at the point (0,1), just like the equation states.
Answer:
The slope is 2.25
The y-intercept is 3
Step-by-step explanation:
Assuming from the cut off picture, that we need to find the slope of ...
y=2.25x +3
y=mx+b form makes it easy to identify the slope and the y-intercept.
m is the slope and b is the y-intercept. Anything number that is in place of m, is the slope; and any nother in place of b is the y-intercept.
In that case, 2.25 is the slope and 3 is the y-intercept
