Use the cubic model y=10x^3-12x to estimate the value of y when x=3

The value of y = 234 when x = 3.

Step-by-step explanation:

The given model function is y =

We need to find the value of y when x = 3.

So, plug in x =3, in the above function, we get

y =

y = 10(27) - 36

y = 270 - 36

y = 234

So, the value of y = 234 when x = 3.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
