Answer:
Step-by-step explanation:
First, you know that Matti's number of pencils is equal to c + 1. C represents Chang lin's amount of pencils. R, which is Renaldo, is equal to c x 3. However, you can't solve this equation without the total number. Perhaps was there something you forgot to include?

Step-by-step explanation:
Answer:
37.8metres
Step-by-step explanation:
The arc of the arrow can be modeled by the equation:
y=-0.02x²+0.65x+4
Where x is the horizontal distance (in meters) from Linda and y is the height (in meters) of the arrow.
The arrow hits the ground when its height (y) is zero.
Therefore, we determine the value(s) of x for which:
y=-0.02x²+0.65x+4=0
Using a calculator to solve the quadratic equation:
x=37.79 or -5.29
Since the distance cannot be a negative value, we ignore -5.29.
The distance from Linda when the arrow hits the ground is 37.8metres (to the nearest tenth)
X=-2
In standard form:
x=2^-1
Hope this helps :)
