How can you determine if an equation will have: One solution
No solution
Infinitely many solutions

if you cancel out all of the X terms via addition or subtraction, and you get something along the lines of 1= 2, then you have no solution.

11× +4=11×7 subtract 11 X from both sides 4=7 no value for x will satisfy this equation. if you cancel out all the EX terms via addition or subtraction and you get something along the lines of 1 equals 1, then you have infinity solutions.

2(× +1)=2×+2 expand the left side by using distributive property. 2 x+2=2×+2 subtract 2 X from both sides. 2 equals to every value for x will satisfy this equation if you can't cancel out all the X terms of addition or subtraction, you probably have one solution.

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
