Answer:
x=0
Step-by-step explanation:
3+5(0)=3
Let x = the next score
If (81 + 89 + 90 + 83 + 77 + x) ÷ 6 = 82
⇒ 420 + x = (82 × 6)
⇒ x = 492 - 420
x = 72
Thus to get an 82 average he need to get 72 on his next test.
-1/2 ÷9/5
=-1/2*5/9
=-5/18. answer.
-1*5 =5 numerator
2*9=18 denominator
Answer: {3, 5, 7}

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input. The output values are y = 3, y = 3, y = 3, y = 5, y = 7. So we simply list these outputs without the "y=" portion. Toss out any duplicates. Only write the unique output values.
The curly braces surrounding the list of values tells us that we have a set.
Answer with Step-by-step explanation:
We are given function
a.From given we can see that
When x approaches to infinity then y also approaches infinity.
When x approaches-infinity then y also approaches infinity.
b.To find the x-intercept
Substitute y=0
x=2
x-intercept:(0,0),(2,0),(-2,0)
To find the y-intercept
Substitute x=0
y-intercept:(0,0)
