(C) jasmyne is the one with the proportinal relationship
Answer:
8.1.
Step-by-step explanation:
a^2+b^2=c^2
8^2+2^2=c^2
64+4
68
and you square root it and get 8.2 so i giras is 8.1
hope it helps.
5/12 equals to 20/48.
48÷12=4
5×4=20
The best to do this is like this:
5 hundred thousand would be 500,000
12 of 10,000 (should be 12,000)
1,000 tens is 10,000 plus 15 tens is 150 so this is 10,150
7 ones
522,157
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
