One of the lines is a horizontal line that crosses the y axis at (0,-1)...it has a solid line...it is shaded above the line...so the equation for that line is : y > = -1.
ur other line has a y int of (0,0), it has a slope of -1/2 ....it has a dashed line...it is shaded below the line.....so the equation for this line is : y < -1/2x
so ur answer is : y > = -1 and y < -1/2x
Answer: -1
Step-by-step explanation:
To find the slope fo the line with the given points, you use the formula
.
![m=\frac{-1-6}{8-1}=\frac{-7}{7} =-1](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-1-6%7D%7B8-1%7D%3D%5Cfrac%7B-7%7D%7B7%7D%20%3D-1)
Now, we know that the slope is -1.
Answer:
B. (x - 2)(x + 2)
Step-by-step explanation:
The answer is b. If you have (x + a)(x - a), the variables will cancel each other out. For example, if we take the answer (x - 2)(x + 2) and factor it out, we get:
x² - 2x + 2x - 4
Then it becomes just:
x² - 4 because the x to the power of one has been canceled. This proves his theory wrong.
I need this answer too I don't know it :(
Answer:
-3
Step-by-step explanation:
First you subtract the first equation from the second one and you get:
3x + 3y = 3
x + y = 1
y = 1 - x
Then you use it on the first equation
888x + 889 (1 - x) = 890
888x + 889 - 889x = 890
-x = 1
x = -1
y = 1 - x
y = 1 - (-1) = 2
Now that you have those two numbers, we have to subtract the value of x from y:
x - y
-1 - 2 = -3
Hope this helps bro
