Run and nug is the answer
Factor out -x from the expression
9514 1404 393
Answer:
9. c. 1
10. c. y = 15/x
Step-by-step explanation:
The equation for inverse variation can be written as ...
y = k/x
The value of k can be determined from given values of x and y. Multiply by x to get ...
k = xy
Solving for x, you get ...
x = k/y
___
9. k = (1/7)(49) = 7
x = k/y = 7/7
x = 1
__
10. k = (3)(5) = 15
y = 15/x
Pythagorean Theorem: a^2+b^2=c^2
Plug in values.
15^2+sqrt(207)^2=(12sqrt(3))^2
225+207=432
432=432
Yes, this is a right triangle.
Answer:
28980
Step-by-step explanation:
420 is equal to 42 times 10, 420 = 42 * 10
Instead of 69 * 420, you can write 69 * 42 * 10
69 * 42 is 2898, now multiply the product by 10 (move the decimal place one place to the right)
2898.00 * 10 = 28980.0 = 28980
Hope this helps :)
Have a great day!
