Answer:
49
Step-by-step explanation:
The given function is .
We expand to get:
We complete the square to obtain the vertex form as follows:
This function is now of the form:
, where (h,k)=(-4,49) is the vertex.
The y-value of the vertex is therefore 49
A. y=2x + 6/5
B. y= 5/6x +2
C. y=2x + 5
D. y=6/5x + 2
Answer: The correct answer is D.
Step-by-step explanation:
b. Ann's car used 7 gallons of gas during a trip. How far did Ann drive?
Answer:
a. .
b. 266 miles.
Step-by-step explanation:
Let y represent distance in miles and x represent gallons of gas.
a. First of all, we will find mileage of Ann's car by dividing total distance traveled by total fuel consumed.
Since Ann's can travels 38 miles per gallon, so distance covered by using x gallons on gas would be .
Therefore, our required equation would be .
b. To find distance covered by Ann's car using 7 gallons, we will substitute in the equation:
Therefore, Ann's car will travel 266 miles in 7 gallons of gas.
Answer:
a. Since Ann's can travel 38 miles per gallon, so distance covered by using x gallons on gas would be 38x. Y=38x
b. Ann's car will travel 266 miles in 7 gallons of gas.
