Answer:
<span><span><span>f<span>−1</span></span><span>(x)</span></span>=<span><span>x−3</span>2</span></span>
Explanation:
Follow the steps:
<span><span>f<span>(x)</span></span>=2x+3</span>
1- replace <span><span>f<span>(x)</span></span> with y →y=2x+3</span>
2- simply switch <span>x and</span> so the equation looks like <span>x=2y+3</span>
3- use algebra to solve<span> for y</span>. (isolate y)
<span>x=2y+3</span>
<span>x−3=2y</span>
<span><span><span>x−3</span>2</span>=y</span>
This is the inverse function and is written as
<span><span><span>f<span>−1</span></span><span>(x)</span></span>=<span><span><span>x−3</span>2</span></span></span>
42 ft^2
Subtracting ‘blank’ space from a larger figure:
(5*12) - (6*3) = 42
60 - 18 = 42
5*12 = 60
6*3 = 18
Breaking down the figure into smaller figures:
(12*2) + (3*3) + (3*3) = 42
12*2 = 24
3*3 = 9
3*3 = 9
80 ( i think )
sorry if it's wrong but im pretty sure that is it
Answer:
9
Step-by-step explanation:
Answer:
2/3 is the slope and
-1 is the y intercept
Step-by-step explanation:
y = 2/3 x -1
This is in the form y = mx+b where m is the slope and b is the y intercept
2/3 is the slope and
-1 is the y intercept
