Answer:
Slope is -2/7
Step-by-step explanation:
Slope formula is y₂-y₁/x₂-x₁
So...
(x₁,y₁) and (x₂,x₂) →(2,2) and (-5,4)
4-2= 2
-5-2= -7
2/-7
The first triangle’s area is 48.75. But since you round it to the nearest tenth, it’s 48.7.
Use the formula a=1/2bh to find the area of a triangle.
A= 1/2• 13 • 7.5
A= 6.5• 7.5
A= 48.75 —-> 48.7 square inches.
Sorry, I can only do one because of homework, but make sure to use that formula! Hope this helped.
Answer: 
Step-by-step explanation:
Let be "x" the amount of miles light will travel in 4,200,000 seconds.
Rewrite 4,200,000 seconds in Scientific notation. Move the decimal point 6 places to the left. Then:
According to the exercise, light travels
miles in 1 second.
Therefore, based on this data, you can set up the following proportion:

And finally, you must solve for "x" in order to find its value.
(Remember the Product of powers property:
)
