Answer:
The number is - ½
Step-by-step explanation:
Let the missing number be x
2x + 4 = 3
2x = 3 - 4
2x = - 1
x = - ½
Answer:
x = 5/2
Step-by-step explanation:
Answer:
Henry walks 7 kilometres from school to library
Step-by-step explanation:
Given:
1 unit = 1 Kilometre
To Find:
The distance between the library and the school
Solution:
The map below shows that Henry has walked from
-2 coordinate in the x axis to coordinate 5 along the same x axis
So he has walked a total of 7 units
Since we know that 1 unit = 1 Kilometre,
7 units will be
=> 7 x 1
=> 7 Kilometres
Ans(a):
Given function is 
we know that any rational function is not defined when denominator is 0 so that means denominator x+4 can't be 0
so let's solve
x+4≠0 for x
x≠0-4
x≠-4
Hence at x=4, function can't have solution.
Ans(b):
We know that vertical shift occurs when we add something on the right side of function so vertical shift by 4 units means add 4 to f(x)
so we get:
g(x)=f(x)+4

We may simplify this equation but that is not compulsory.
Comparision:
Graph of g(x) will be just 4 unit upward than graph of f(x).
Ans(c):
To find value of x when g(x)=8, just plug g(x)=8 in previous equation




4x+16=3x-1
4x-3x=-1-16
x=-17
Hence final answer is x=-17
A) (-4,2π/3)
b) (4,4π/3)
c) (-2,π/3)
d) (2,5π/3)
