Answer: I THINK A function f (x) is called increasing in an interval [a,b] when f' (x) > 0 in the interval (a,b). That is, in that interval, with increasing the value of x the value of f (x) increases. Let f (x) be the function which is shown in the given diagram.
Step-by-step explanation:
Answer:2x+7=9
Step-by-step explanation:
When it says seven more you add that to the end of the equation and set it equal to 9 then product of a number (x) and 2 so it would be 2x. Hope this helps!
Answer:
15C is 59F
Step-by-step explanation:
As an equation, F = (1 4/5)C + 32. 1 and 4/5 is the same as 9/5.
Substitute 15 for C.
F = (9/5)C + 32
F = (9/5)(15) + 32 Multiply 15 by the top number in 9/5
F = 135/5 + 32 Convert 32 to a fraction over 5
F = 135/5 + 160/5 Add the numerators under the same denominator
F = 295/5 Divide
F = 59 Degrees in Farenheit
Therefore 15°C is 59°F.
Supplementary angles because they add to 180 degrees
Answer:
4 1/12
Step-by-step explanation:
a = 5/6 b = 3 1/4 = 13/4
To add 5/6 + 13/4, we have to make the denominators the same:
20/24 + 78/24 = 98/24
To make it back to a mixed fraction:
4 2/24
4 1/12
