You forgot to provide the slope but here is how you do this
the slope 5 = (y2 - y) / (x2 - x) but we know that (x2, y2) = (-10, -5)
=> (-5 - y) / (-10 - x) = 5 --- multiply both sides by (-10 - x)
=> (-5 - y) = 5 (-10 - x)
=> (-5 - y) = -50 - (5)x --- add +5 to both sides
=> -y = (-50 + 5) - (5)x --- multiply both sides -1
=> y = 5x + 45 --- this will be your equation.
Answer:
9. x=-6, y=0
10. x=-9, y=-10
11. x=3, y=-1
Step-by-step explanation:

Multiply the first equation by 2.

Add the equations.


We figured out x now we have to figure out y. To figure out y plug in x into any equation.




Your answer is x = -6 and y = 0 for number nine.

Change the signs of the second equation becuase 3y and 3y are both positive. We need one of them to be negative.

Add them.


Now we have to figure out y.




x=-9 and y=-10 is your answer to number ten.








x=3 and y=-1 is the answer to number eleven. I hope this helps! Let me know if I got anything wrong.
Answer:
400 mm
Step-by-step explanation:
to convert cm to mm, you add a 0, or more specifically, multiply by 10. so, 15 × 10= 150. 250+150=400.
The percentage of published studies that supported the tested hypothesis has changed from 70 to 85% over the past 25 years.
Hypothesis testing:
A hypothesis testing means investigates a proposed mathematical model to determine whether there is sufficient evidence from a sample of data to reject the defined null hypothesis.
Given,
The percentage of published studies that supported the tested hypothesis has changed from _____ to _____ over the past 25 years.
Here we need to find the change in the percentage for the past 25 years.
Based on the details, the percentage of published studies that supported the tested hypothesis has changed from 70 to 85% over the past 25 years.
