Answer:
40
Step-by-step explanation:
2x+100=180
-100 -100
2x =80
/2 /2
x =40
Answer:
just subtract
Step-by-step explanation:
first go number by number and then subtract them and see the average rate of change and input that number
Answer:
Answer is two
Step-by-step explanation:
Let’s go backwards
-25-9= -34
So x= -34
Let’s test this out:
-34 +9= -25
Hope this helped
Answer:
[2, positive infinity)
Step-by-step explanation:
the range is the interval of possible y-values or f(x) values.
for x<0 y is always and only 3.
for x between 0 and 2, y = x² + 2.
it clearly increases with increasing x. so, what is y for the smallest x ? the smallest x here is 0.
y = 0² + 2 = 2
for x larger or equal to 2, y = (1/2)×x + 5.
it again increases with increasing x. the smallest x here is 2.
y = (1/2)×2 + 5 = 1 + 5 = 6.
so, the smallest possible value for y is 2. and then it will approach positive infinity, when x approaches positive infinity. but it can never reach that (only after infinite time and at infinite x, so it is officially undefined), so that the interval is open on that end.
