PLZZ HELP i need this to be right Select the correct answer from the drop-down menu.
The equation _ has no solution.
Is it
1 2 3 or 4

4

Step-by-step explanation:

One:

13y+2-2y=10y+3-y

* first step is to simplify (combine like terms) *

11y+2=9y+3

* Subtract 2 from both sides (you want like terms on the same side) *

11y = 9y + 1

* Subtract 9y from both sides (again you want like terms on the same side) *

2y = 1

* Divide through by 1 *

y = 1/2

Two:

9(3y+7)-2=3(-9y+9)

* Simplify (combine like terms) *

27y+61=-27y+27

* Subtract 27 from both sides*

27y+34=-27y

* Subtract 27y from both sides*

34=-54y

* Divide through by 34 *

y = -17/27

Three:

32.1y+3.1+2.4y-8.2=34.5y-5.1

* Simplify (combine like terms) *

34.5y-5.1=34.5y-5.1

* From here you can see that all real numbers would work *

All real numbers

Four:

5(2.2y+3.4)=5(y-2)+6y

* Simplify (combine like terms) *

11y+17=11y-10

* The 11y s would cancel leaving you with no solution*

No solution

step-by-step explanation:

- "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."
