Answer:
Grade≥69(at least 69)
Step-by-step explanation:
(77+69+65+x)/4=70
x=69
so he must get 69 or more
Answer:
-1<-0.25
With -1>0.25 you have a negative(-1) and a positive(0.25) the negative will always be less than the positive proving the equation wrong
Moving onto -1<-0.25 this one is a little trickier because they both have a negative so this is where you look at the number line and see which number is closer to 0 and whichever number is is greater meaning this is the correct answer.
Answer: 1540
Explanation: Just multiply or use a calculator. The prime factorization is all the prime factors, meaning you can multiply all of them to get the original number.
Answer:
Option 3
Step-by-step explanation:
If (x, y) is on h(x), then (y, x) is on the inverse.
Thus, if (4, 2) is on the inverse, then (2, 4) must be on the original. (Which it is not, so this option is incorrect)
If (0, 1/2) is on the inverse, then (1/2, 0) must be on the original. (It is not, so this option is also incorrect)
If (0, 1) is on the inverse, then (1, 0) must be on the original. (It is not, so this option is also incorrect)
If (-5, 1) is on the inverse, then (1, -5) must be on the original. (It is not, so this option is incorrect)
The correct answer would be the third option.
