That might not be as hard to answer as you just take the . away and then you're left with 249 centimeters :)
<h2>(x, y) = (21/13 , 84/13)</h2>
Step-by-step explanation:
x + 3y = 21
- 4x + y = 0
y = 4x
<h2>_____________</h2>
x + 3y = 21
x + 3(4x) = 21
x + 12x = 21
13x = 21
x = 21/13
y = 4x
y = 4 (21/13)
y = 84/13
(x, y) = (21/13 , 84/13)
Answer:
A'(-6,4)
Step-by-step explanation:
A transformation of (x, y) → (x-3, y + 2) means:
- x coordinate gets translated 3 units left [we subtract 3 from original x coordinate]
- y coordinate gets translated 2 units up [we add 2 to original y coordinate]
The original x coordinate is -3 so we subtract 3 from it to get:
New x = -3 -3 = -6
The original y coordinate is 2 so we add 2 to get:
New y = 2 + 2 = 4
So A' is
A'(-6,4)
The answer is that f-1(3) = 7.
In order to find the answer, we first must find the inverse function. The f-1 indicates that we are looking for an inverse. To find any inverse, we first must switch the x and f(x) values. We then solve for the new f(x), which gives us the inverse.
f(x) = (2x - 2)/4 ----> Switch x and f(x)
x = (2f(x) - 2)/4 -----> Multiply both sides by 4
4x = 2f(x) - 2 ----0-> Add 2 to both sides
4x + 2 = 2f(x) ------> Divide both sides by 2
f-1(x) = (4x + 2)/2
Now that we have the inverse function, we can put in 3 and find the answer.
f-1(x) = (4x + 2)/2
f-1(3) = (4(3) + 2)/2
f-1(3) = (12 + 2)/2
f-1(3) = (14)/2
f-1(3) = 7
