The answer is either the first or second if u can put 2 down then both
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.
Answer:

Step-by-step explanation:
move the variable to the right(-2x) and change the sign(2x now) -3y=-12+2x then change the signs (-3y is 3y , -12 is 12 and then 2x becomes -2x again) then divide both sides of the equation by 3 so 12÷3=4 and -2x÷3=
then you're going to use the commutative property to reorder the terms . so your answer is 
I'm gonna go with triangle B. Triangles A,C,and E all look to be somewhat congruent in that they're all equilateral. Triangle D and F look similar but Triangle b looks like its isosceles and the others aren't like that.
Answer:
60
Step-by-step explanation:
If all triangles equal 180 degrees, then all you have fo do is divide 180 by the number of points a triangle has
