I dont like math please help me:(

y = x²+8x+7

Step-by-step explanation:

according to the table, we get the point :

(-4, -9) as the vertex and (0, 7) as y-intercept

y = ax²+bx+c

=> the symetry axis :

x = -b/2a = -4

b=-4×2a = 8a

let a=1, => b = 8(1) = 8

y-intercept = (0, c) =(0, 7) => c =7

so, the equation might be :

y = x²+8x+7

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
