Solve for x. 2(2-x) + 12x =44

Mathematics
1 answer:
Nataly [62]3 years ago
8 0

Answer:

2(2-x)+12x=44

4-2x+12x=44

-4             -4

-2x +12x = 40

10x=40

/10   /10

x=4

Step-by-step explanation:

first you multiply the (2-x) by 2, you then subtract the 4 from both sides of the equation, you end up with -2x +12x = 40. Then subtract the 2x from the 12x and you end up with 10x. so now 10x=40. You then divide both sides by 10 and end up with x=10

sorry im not to good at explaining haha

What is the solution set to the inequality - 3x + 2 > 17
zepelin [54]
The answer would be x<-5

Explanation
You have to move 2 over to the 17 to get the x by itself so since it’s a positive 2, you would subtract 2 which would give you -3x>15. THEN you would divide the 15 by negative 3 which gives you -5 BUT since you are dividing by a negative you would flip the sign.
Hope this helped!!

What is the range of the function f(x) = 2x + 1 given the Domain D = {-1, 0, 1, 2}?
Artemon [7]
For this case, the first thing we must do is evaluate the function in each of the domain points.
 We have then:
 f (-1) = 2 (-1) + 1 = -2 + 1 = -1
 f (0) = 2 (0) + 1 = 0 + 1 = 1
 f (1) = 2 (1) + 1 = 2 + 1 = 3
 f (2) = 2 (2) + 1 = 4 + 1 = 5
 The range of the function will then be:
 R = {-1, 1, 3, 5}
 Answer:
 
The range of the function f (x) = 2x + 1 given the Domain D = {-1, 0, 1, 2} is:
 R = {-1, 1, 3, 5}
