Answer:
The answer is option B
Step-by-step explanation:
Since the figure above is a right angled triangle we can use trigonometric ratios to find y
To find y we use tan
tan∅ = opposite/ adjacent
From the question
is the adjacent
The opposite is y
So we have
<h3>But
<h3>That's
<h3>Cross multiply
We have the final answer as

<em>For this </em> <em>equation, we can first identify the components.</em>
f(x) is the output, or the y-coordinate.
a is the initial amount
b is the base
x is the input, or the x-coordinate.
<em>Next, we can identify known variables. </em>
We know for sure that the base is 2, since it is given in the problem.
We can also safely assume that since (4,4) is on the line, or the function, that it must be a solution of the equation.
Thus, (4,4) allows us to conclude that 4 is our x-coordinate and 4 is our y-coordinate.
<em>Plug in known values. </em>
<em>Simplify the problem. </em>
<em>Divide by 8 on both sides to get a alone. </em>
<em>Plug in all values again, with the known value, and without the x and the f(x) value. </em>
Answer:
See attached picture.
Step-by-step explanation:
To graph the linear equation, convert x+y=4 into y= -x+4. This means that y= mx+b is y=-x+4. So m = -1 and b =4.
Start with b by finding 4 on the y-axis. Plot a point. Then from this point move down 1 unit and 1 unit to the right to (1,3). Plot this point. Connect the points.
