f(x)=2x^2+0x-5
Find the vertex
0/4=0=x
Input x into the equation to find y or f(x)
0+0-5=f(x)
(0,-5) = Vertex
Now find a random x coordinate to input into the equation.
Let's do 4.
32+0-5=f(x)=27
It may not look like a parabola due to it being uneven.
Answer:
x is 122

Answer:
Julia has enough gas to mow the two yards.
Step-by-step explanation:
Given:
Julia needs 
gallon of gas to mow first yard.
Julia needs 
gallon of gas to mow second yard.
Julia has a total of 
gallon of gas in in her can.
To find whether she has enough to mow both yards.
Solution:
Total gallons of gas needed to mow two yards can be found out by :
⇒ 
Taking LCD =80.
⇒ 
⇒ 
Adding the numerators.
⇒ 
⇒ 1.2125 gallons
Julia has gallon = 1.5 gallons of gas in in her can.
Since 
, thus we can say that Julia has enough gas to mow the two yards.
Answer:
Speed = 0.1333 km/minute
Step-by-step explanation:
According to the graph :
At 10 minutes, it could be observed that the Distance moved started to reduce until distance moved reached 0 at 20 minutes. This could be interpreted as a case of negative acceleration (that is deceleration) whereby the distance covered started to decrease with time until the it rest at 0.
Speed during the last 30 minutes :
Speed = distance / time
Distance moved during this period :
Distance (from 0 to 4km)
Time = (from 30 to 60 minutes)
Speed = (4 - 0) / (60 - 30)
Speed = 4 / 30
Speed = 0.13333 km per minute
Answer:
72
Step-by-step explanation:
Find the prime factorization of 18
18 = 2 × 3 × 3
Find the prime factorization of 24
24 = 2 × 2 × 2 × 3
Multiply each factor the greater number of times it occurs in steps above to find the LCM:
LCM = 2 × 2 × 2 × 3 × 3
LCM = 72
i hope this helps :)
