Answer:
Real and irrational numbers
Answer:
x + y = 2
y = 2 - x
so it is a linear equation.
2x + 5 = 11
2x = 11 - 5
2x = 6
x = 3
it is not a function because for just one <u>x</u> we have many <u>y</u>
the answer is the first one A
Answer:
use distance formula for the sides of the triangle
Answer : D
From the given graph , we can see that
The graph crosses the y axis at 7
So y axis is (0,7)
The graph is increasing at first and reaches (-2,8) and then start decreasing
The graph start increasing at x=-10 and goes on increasing till x= -2
then the graph start decreasing at x=-2 and goes in decreasing till x= 10
The graph crosses the y axis at (0,7), increasing from x=-10 to x=-2 and decreasing from x=-2 to x=10
Answer D is correct
