Answer:
x ≥14
Closed circle at 14 line to the right
x≤3
closed circle at 3 line to the left
Step-by-step explanation:
(x-4)/5 ≥2
Multiply by 5
(x-4 )/5 *5 ≥2 *5
x-4 ≥10
Add 4 to each side
x-4+4≥10+4
x ≥14
Closed circle at 14 line to the right
3x-4 ≤5
Add 4 to each side
3x-4 +4≤5+4
3x ≤9
Divide by 3
3x/3 ≤9/3
x≤3
closed circle at 3 line to the left
3x+2/5=7
3x+2/5=35/5
3x=35/5-2/5
3x=33/5
x=(33/5)/3
x=(33/5)/(3/1)
x=(33/5)*(1/3)
x=33/15
x=30/15+3/15=2+1/5
x=2.2
Answer:
86% of 950 is 817
Step-by-step explanation:
You convert the fraction into a decimal by moving the point two spaces to the left. You then multiply .87 by 950 to get 817
Answer:
i.e. The inverse function
i.e. The French size of a dress if it is U.S. size 10 is 42.
Step-by-step explanation:
Given
Solving (a): The inverse function
Replace d(x) with y
Swap y and x
Make y the subject
Replace y with d'(x)
Hence, the inverse function is:
Solving (b): US size of 10
Substitute
