Ok so for part A, the x-coordinate of the intersection is the solution to <span><span>2<span>−x</span></span>=<span>4<span>x+3.
Part B </span></span></span><span>y>3x+10</span> for (8,10)
<span><span><span>10>3(8)+10</span><span>10>34
I am not sure about the thrid one
</span></span></span>
Answer:
(x, y) = (4, 0)
Step-by-step explanation:
It looks like you want to solve ...
Adding the two equations gives ...
2x = 8
x = 4 . . . . divide by 2
Then ...
y = 4 - x = 0
The solution is (x, y) = (4, 0).
_____
If you think about what you're seeing when you read the equations, you realize that adding or subtracting y gives the same result. Hence y=0 and x=4.
-4 < -12 would be my answer, just from looking at it. If you write it out on a number line, the number -4 is higher than -12. The higher the negative number, the lower it is on the line. So, -4 is greater than -12, not lower than.
Answer:
C
Step-by-step explanation:
You first distribute within the parentheses which is -(-z-2). This is going to make everything positive as everything in the parentheses is negative. You should get z+2. Next, you plug that back in. It should be-3z+z+2. You simplify to get -2z+2. Hope this helps!
Answer:
20
Step-by-step explanation:
40 - 15 = 25
25/1.25=20
