Answer: C
<u>Step-by-step explanation:</u>
f(x) = x²
g(x) has the same vertex as f(x) but is wider so has a vertical stretch by a factor of (1/3).
g(x) = (1/3)x²

Answer:
d
Step-by-step explanation:
2 × -5 = -10
so number line should graduate from -5 to -10
Answer: There are 24 traffic lights on Berry Boulevard.
Step-by-step explanation:
Since we have given that
Total length of road = 
Number of roads on every 
= 2
So, According to unitary method,
In every , number of roads = 2
In every 1 mile, number of roads = 
So, in every 
the number of roads = 
Hence, there are 24 traffic lights on Berry Boulevard.
8x^2+6x^2+4x=138 combine like terms on left side
14x^2+4x=138 since the number of seats in the from row is just 4x, subtract 14x^2 from both sides
4x=138-14x^2 that would be the general solution, if you wanted the actual number you would have to solve for x and then multiply that value by 4 to know what "4x" is...
14x^2+4x-138=0
14x^2-42x+46x-138=0
14x(x-3)+46(x-3)=0
(14x+46)(x-3)=0
2(7x+23)(x-3)=0, since x>0
x=3 and thus
4x=12 seats
So there are 12 seats in the front row addition.
