The answer is or has to be 10%
Answer:
B. 3/2
Step-by-step explanation:
If f(x) and are inverse, that means that if we switch the x and y for f(x) and solve for y, we will get the inverse function.
Knowing that f(x) = 2x + 5, let's write this as y = 2x + 5 and switch the x and y:
x = 2y + 5
Now, solve for y:
x = 2y + 5
x - 5 = 2y
y = (x - 5)/2
That's the function:
Plug in 8 for x:
The answer is thus B.

Just subisute values that will work
one easy way is to make one sides equal to only one of the placeholders, like y, and then lug in values in for x exg
x+2y=3
subtract x from both sides
2y=3-x
divideb bith sides by 2
y=-1/2x+3
subsitute valudes for x and get values for y
if x=2 then
y=-1/2(2)+3
y==-1+3
y=2
when x=2, y=2
when y=0 then y=3
Answer:
2
Step-by-step explanation:
do 9 plus negative 5 then divide by 2 to get your answer
Given :
A square of side 18 cm.
To Find :
Angle V on the square.
Solution :
This problem can be done easily without using pen and paper but we need to know the property of diagonal of square given below :
The diagonals of the square bisect each other at 90°.
This will hold true for any right angle triangle.
Therefore, the angle V on the square is 90°.
