Answer:
Third option:
Explanation:
The third option states that...
The graph crosses the y axis at (0,-5), which is correct. (0,-5) is the y-intercept of this graph.
The graph decreased from x=-10 to x=-2, which is also true. We can see a decrease starting from when x=-10 that ends when x=-2.
The graph remained constant from x=-2 to x=-10, which is correct. We do not see an increase or decrease on this graph from when x=-2 to when x=10.
I hope this helps! Please comment if you have any questions.
First you get a graphing calculator & enter the equation into y = then hit graph . then hit graph & y= to get the table find where y is 0 and those will be you answers
(-0.583, 0) (8.583, 0)
Answer:
14 and 6
Step-by-step explanation:
Let's start by naming the first number x.
We can name the second number y.
We can set up equations to model our situation.
x+y=2x-8
x-y=2y-4
Let's simplify the equations.
x+y=2x-8
Subtract 2x from both sides
-x+y=-8
__________
x-y=2y-4
Subtract 2y from both sides.
x-3y=-4
Add the two equations together to eliminate x.
x-3y=-4
-x+y=-8
________
0x-2y=-12
-2y=-12
Divide both sides by -2.
y=6
The second number is 6.
Plug that back in.
x+6=2x-8
Subtract x from both sides
6=x-8
Add 8 to both sides
x=14
The first number is 14
Try it with some random number, like a=3.
Is "3+0 = 0+3 = 0" true? No.
If you were doing multiplication, then it would be true, but not with addition.
