[5,∞) is the domain of y=√2x-10
Answer:
73 and 15
Step-by-step explanation:
I made two variables for this:
x = larger number
y = smaller number
Write an equation for "the sum of two number is 88" and you get:
x + y = 88
Write an equation for "four times the smaller number is subtracted from the larger number" and you get:
x - 4y = 13
I do not want an equation with both x and y in it, so I will rewrite the first one and use substitution in the second one:
x + y = 88 -- move the x to the other side
y = 88 - x
x - 4y = 13 -- substitute for y
x - 4(88 - x) = 13 -- multiply by 4
x - 352 + 4x = 13 -- move -352 to the other side, combine x's
5x = 365 -- divide by 5
x = 73
Now that I know x is 73, I go back to my first equation (x + y = 88) and I get:
73 + y = 88 -- subtract 73 from both sides
y = 88 - 73
y = 15

Shadufs were used as a means of transporting water for irrigation in ancient Egypt. They were used on canals and rivers to bring water to where it was needed.
Hi There!
Answer:
Always True...
For Example:
-0.2 * -0.2 * 0.2 = 0.008
-0.9 * -0.9 * 0.1 = 0.081
Hope This Helps :)
