Find the inverse of the function y= 2x
Valentin [98]

Answer:

y=\frac{1}{2}x

Step-by-step explanation:

To find the inverse of a function, switch the x and y values and isolate y. After switching the x and y values of y=2x, we get x=2y.

Now divide by 2 to isolate y:

y=\frac{x}{2},\\\boxed{y=\frac{1}{2}x}

1-104. Solve each equation. Give solutions in both exact and approximate forms. HomeworkHelpa. X2+3x-3=0b. 3x2-7x=12
Alex_Xolod [135]

According to the given question we have the following equations:

a. x2+3x-3=0

b. 3x2-7x=12

a. X2+3x-3=0

The first step to calculate this equation is:

Move the -3 to the other side:

So, the equation would be:

X2+3x=3

x2+3x=5x

Therefore:

5x=3

x=3/5

a. The value of x would be 3/5

b. 3x2-7x=12

First step:

Multyply 3x to 2, so:

3x*2=6x

Next we can proceed to calculate the value of x:

6x-7x=12

-x=12

x=-12

b. The value of x would be -12

a motorboat travels 305km in 5 hours going upstream and 651km in 7 hours going downstream. What is the rate of the boat in still
Ghella [55]
Recall your d = rt, distance = rate * time.

b = speed rate of the boat.

c = speed rate of the current.


keeping in mind that, as the boat goes Upstream, against the current, it's speed is not "b", but is really " b - c ", because the current is subtracting speed from it.

likewise, when the boat is going Downstream, because is going with the current, is really going faster at " b + c ".

\bf \begin{array}{lccclll}
&\stackrel{km}{distance}&\stackrel{kmh}{rate}&\stackrel{hours}{time}\\
&------&------&------\\
Upstream&305&b-c&5\\
Downstream&651&b+c&7
\end{array}
\\\\\\
\begin{cases}
305=(b-c)(5)\implies 61=b-c\implies 61+c=\boxed{b}\\
651=(b+c)(7)\implies 93=b+c\\
----------------------\\
93=\boxed{61+c}+c
\end{cases}
\\\\\\
93=61+2c\implies 32=2c\implies \cfrac{32}{2}=c\implies 16=c

what is the speed of the boat?  well, 61 + c = b.
