Answer:
x = -1
Step-by-step explanation:
to find axis of symmetry, use the following equation:
x = -b/2a
in this problem, a = 3, b = 6, c = -12
x = -6/2(3)
x = -6/6
x = -1
Answer:
What I DONT KNOW
Step-by-step explanation:
Answer:
y=1x x 5
Step-by-step explanation:
In the input its going up by 1 and in the output its going up by multiplying by 5.
Answer:
Let's see the first two points: (-7, 5) and (-5, 9)
The line passes these points has a form of: y = Mx + b
=> 5 = (-7)M + b
9 = (-5)M + b
Subtract the 1st equation from 2nd equation, we have:
4 = 2M
=> M = 2
Substitute M back into 1st equation:
=> 5 = (-7)*2 + b
=> b = 19
=> y = 2x + 19
or y - 5 = 2x + 14
or y - 5 = 2(x + 7)
=> Option A is correct
Hope this helps!
