Answer:
Step-by-step explanation:
Jenny planned to solve 2/3 of homework
On Saturday she solved 28 problems, which is 7/8 of the planned number
<u>Planned number is:</u>
- 28 : 7/8 = 28 * 8/7 = 32 problems
<u>Jenny's homework was:</u>
- 32 : 2/3 = 32 * 3/2 = 48 problems
Let x= second number
x-1= first number
2x= 4(x-1) + 26
2x= 4x -4 + 26
2x -4x= 22
-2x= 22
(-1)(-2x)=22(-1)
2x= -22
x=-11 (second number)
-11-1= -12 (first number)
the function f(x) = 4(x+3) − 5
Lets find the inverse function f^-1(x)
step 1: Replace f(x) with y
y = 4(x+3) − 5
step 2: Replace x with y and y with x
x = 4(y+3) - 5
step 3: Solve for y
x = 4(y+3) - 5
x = 4y +12 -5
x= 4y + 7 (subtract 7 on both sides)
x - 7 = 4y (divide by 4 on both sides)
Given : x = 3
We plug in 3 for x in the inverse function
= -1
the inverse function when x = 3 is -1
Answer:
The answer should be B
Step-by-step explanation:
to find the net change you need to do final minus initial. So the final would be Jakarta and the initial would be Hong Kong. so just subtract Jakarta's latitude from Hong Kong's and the same for longitude
