Answer:
D
Step-by-step explanation:
2x + 5y = - 10 Subtract 2x from both sides
5y = -2x - 10 Divide by 5
y = -2x/5 - 10/5
y = 0.4x - 2
The slope is minus so the line is going from lower right to upper left as B and D are doing.
The y intercept is - 2. B goes through + 2 so it is not the answer.
The answer is D
Answer: y = 6
Step-by-step explanation:
A square's area can be done by using s^2, where s is y in this case. Because there are 5 squares, the area of the figure is 5y^2. Because the area is also 180cm, 5y^2=180.
Then divide both sides of the equation by 5 to get y^2 = 36. Then square root both sides of the equation to get y = 6.

The athlete's average speed was 300 meters/minute.
<h3>How to calculate the speed of the athlete?</h3>
To calculate the speed of the athlete we must perform the following operations.
Divide the distance into the total time:
Transform the value from seconds to minutes, for which we must multiply 5 by 60 because each minute is made up of 60 seconds.
- 5m/sec × 60sec = 300m/min
According to the above, the average speed of the athlete is 300m/min.
