The distance between two points is given by
Root of (x2 - x1) squared + (y2 - y1) squared
= root of (10 squared )+( -10 squared )
= root of 100 + 100
= root of 200
So, you start by separating the equation into two inequalities and you get
4x+1 > -7 and 4x +1 < 5
Solve these inequalities and you get your final answer:
x > -2 and x < 1
(The equalities symbols are supposed to have the "or equal" line beneath them, I was just too lazy to put them.)
2limes=0.36
we simplify /2
1lime=0.18
times by 3
3limes=0.54
Answer:
The rate of change is "-3". Which means the rate at which the tractor uses fuel.
Step-by-step explanation:
The equation describes a line and any line follows the equation:
y = m*x + c
Where "m" is the rate of change and "c" is the shift on the line. Comparing the equation for the fuel and the equation from the line, the rate of change must be "-3". The rate of change in this context describes the speed at which the tractor uses fuel, at a rate of 3 gallons per hour.
