Answer:
x-3y+12
Step-by-step explanation:
Answer:
The sequence is a function since,
- It maps to a number from each of the numbers or points in it's domain set which is the set of positive integers
- It maps to only one point from each point in it's domain set.
Step-by-step explanation:
This sequence is a function whose domain is the set of positive integers.
The function is given by,
f(x) = 10 + (x -2) when x is even
= (x- 1) when x is odd
The sequence is a function since,
- It maps to a number from each of the numbers or points in it's domain set which is the set of positive integers
- It maps to only one point from each point in it's domain set.
Answer:
66°
Step-by-step explanation:
There are so many ways to get this answer. Angle seven and 5 are vertically opposite so they're equal. Angles 4 and 5 are co-interior so they add up to 180°. If 180 is the total of 4+5, and 5 is 114 then 4 = 180-114 which is 66.
Angles 7 and 3 are corresponding and corresponding angles are the same. 3 and 4 are on a straight line so they add up to 180. 180-114= 66
You can also use angles 8,6 and 2 to get your answer
R(s + t) = st
Rs + Rt = st
Rs - st = -Rt
s ( R - t) = -Rt
*s = - Rt / (R - t) Multiply through by -1 on the right.
*s = Rt / (t - R) Put in the brackets in your answer. What you have been writing means
s = Rt/r - R you need the brackets. The stars mean that either could be an answer. I think your problem could be the brackets. Now I'm reasonably certain this is correct.
Answer:
EF = 58
Step-by-step explanation:
From the question given, we obtained the following information:
DF = 9x – 39
DE = 47
EF = 3x + 10
EF =?
We'll begin by calculating the value of x.
This can be obtained as follow:
DF = DE + EF
DF = 9x – 39
DE = 47
EF = 3x + 10
DF = DE + EF
9x – 39 = 47 + 3x + 10
9x – 39 = 47 + 10 + 3x
9x – 39 = 57 + 3x
Collect like terms
9x – 3x = 57 + 39
6x = 96
Divide both side by 6
x = 96/6
x = 16
Finally, we shall determine the value of EF as follow:
EF =?
x = 16
EF = 3x + 10
EF = 3(16) + 10
EF = 48 + 10
EF = 58
