We have been given that a factory purchased a 3D printer in 2010. The value of the printer is modeled by the function , where x is the number of years since 2010. We are asked to find the value of printer after 10 years.
To find the value of printer after 10 years, we will substitute in our given equation.
Upon rounding to nearest hundredth, we will get:
Therefore, the value of the printer after 10 years would be approximately 14.52.
The ans is B (-1, -5)
Thus y +5=2(x+1)
Substitute (-1, -5) into the equation
-5 +5=2(-1+1)
0=0
Answer: Dakota was less than 51 inches last summer.
Step-by-step explanation: First of all let us represent Dakota's height last summer by letter x.
The height requirement for the roller coaster is given as 54 inches. This means Dakota must be 54 inches or higher in order to be allowed on the ride. However, Dakota is too short to ride. This can be represented mathematically as x < 54.
If However, last summer Dakota grew 3 inches taller, then we can also represent this mathematically as x + 3 < 54.
To solve for this;
x + 3 < 54
Subtract 3 from both sides of the inequality
x < 51. (That is x is less than 51)
Since Dakota's height has been represented by x, we can now interpret this inequality as;
Dakota was less than 51 inches tall last summer.
