In order to evaluate the given function at x = -3, simply replace "x" in the function with -3 and solve.
<em>Multiply -4 and -3 in the function above.</em>
<em>Add 3 on both sides of the equation.</em>
<em>Add 2y on both sides of the equation.</em>
<em>Divide both sides of the equation by -3.</em>
Therefore, at x = -3, the value of y = -5. Hence, f(-3) = -5.
Answer:
f(-3) = -5
<em />
(m - 3)(m + 5)= 0
m= {3, -5}
So normally it is
if 8x is to 6y, then how many x is to 42y?
it could be
if 8x:6y then how many x:42y or
if 8x:6y then how many y:42 x
I will solve for both
if it is
x:42y go to AAAAAAAA
if it is
y:42x then go to BBBBBBBBBB
AAAAAAAA
how many concerts are equal to 42 symponies
arrange in concerts to symponies format
8:6=x:42
fractionify
8/6=x/42
multiply boht sides by 42
336/6=x
56=x
56 concerts equals 42 symponies
BBBBBBBBBB
how many symponies are equal to 42 concerts
areange in symponies:concerts
6:8=x/42
fractionify
6/8=x/42
multiply boht sides by 42
252/8=x
31.5=x
31.5 symponies to 42 concerts
so it could be
56 concerts to 42 symponies
or
31.5 symonies to 42 concerts
Answer:
<h3>b. y=arcsinx</h3>
Step-by-step explanation:
Given the function y = sinx
The equation of its inverse can be gotten by first taking the arcsin of both sides as shown
arcsiny = arcsin(sinx)
The arcsin will cancel out the sin function at the right hand side to have;
arcsiny = x
x = arcsiny
Replacing the variable 'y' with x and 'x' in y in the resulting equation we have;
y = arcsinx
This gives the required inverse.
