Answer:
Yes, it makes it true
Step-by-step explanation:
Plug in 3 and 10 as x and y into the inequality:
y > 2x + 2
10 > 2(3) + 2
10 > 6 + 2
10 > 8
Since 10 is bigger than 8, this inequality is true.
So, (3, 10) makes the inequality true.
Answer: She uses more than 2 cups of water per day.
Step-by-step explanation:
It takes 2 minutes to brush your teeth and if you times that by 3 you get 6 so she spends 6 minuntes per day brushing her teeth and water runs fast. so if your leaving the water on for 6 mintues your filling up much more than 2 cups
Rememember you can do anything to an equation as long as you do it to boht sides except diviede by zero and when you mulitply by a negative with inequalities (<u><</u>, <,<u>></u>,>) remember to flip the sign
sum means add
twice a number means a number times 2 (represented by x)
greater than means >
3 times means multiply
minus is minus
so
sum of twice a number and 5 (2x+5) is greater than (>) 3 times the number (3x) minus 3 (-3)
we now have
2x+5>3x-3
subtract 2x from both sides
5>x-3
add 3 to both sides
8>x
x<8
therefor x is any number less than 8
x can be 7,6,5,4,3,2,1,0,-123189030, π
basically x<8
the son was 0 so just subtract the kids age.
If you mult. these two radicals together, you'll combine the radicands -15 and -6 into one amount: 90, and this 90 is under the radical: sqrt(90).
Now, 9 is a perfect square, tho' 10 is not. Thus, sqrt(90) = 3sqrt(10) (ANSWER)
