Answer: x=-1
Step-by-step explanation:
the x value of the vertex = -b/2a if the equation is in "ax^2+bx+c" for
you are in luck
x value of the vertex = -4/4 = -1
the line of symmetry is a vertical line, and since it must pass through the vertex
line of symmetry: x=-1
Addictive property Becayse it’s adding and it’s using that type of property. D
Answer- A- 20, B-70, c-20, d-50, e- 110
I think
5 - 17
x is adding multiples of 3 to get y
example: 2+3=5, 3+6=9 4+9=13, 5+12=17 and so on.
C. 85%
Set up the proportions
136/160 = ?/100
Then cross multiply.
100 x 136 = 13600
13600/160 = 85
Also you could use process of elimination. 296% wouldn’t work because that’s saying 136 is almost 3 times as many as 160. The other answers wouldn’t work because it’s clear that 136 is more than half of 160.
