The ordered pairs are probably (0,10) and then (-1,5).
Answer:
2x+23
Step-by-step explanation:
The perimeter of a triangle is calculated by adding the sum of all sides.
Therefore, in the given problem, the perimeter will be:
Perimeter = 21-x + 2x-3 + x+5
= 2x+23
I'm pretty sure the answer to this is x=65 but I could be wrong.Not very good with this kinda Algebra.
its in vertex form
-3 means is open down or looks like this ∩
the vertex is (-2, 7) - opposite of the number in brackets and the constant 7
so it increases from - ∞ to -2 and decrease after
g) - ∞ to -2
h) -2 to ∞
i) at the ends it points down to - ∞
j) multiply is out at put it in ax² +bx + c standard form, its in vertex
