Step-by-step explanation:
When the problem says 3f(x), it means that you are multiplying f(x) by 3. The same goes for 2g(x).
Now, we subtract f(x) from g(x) after being multiplied.
The number of people who grow potatoes is 3 times the number that grow sugar beet.
⇒ 48 + x = 3( x + 12)
--------------------------------------------
Solve for x :
--------------------------------------------
48 + x = 3( x + 12)
48 + x = 3x + 36
2x = 12
x = 6
--------------------------------------------
People who do both grow either.
--------------------------------------------
Number of people who does not grow potato or sugar beets = 100 - 48 - 12 - 6 = 34
------------------------------------------------------------------------------
Answer: The answers are 6 and 34.
------------------------------------------------------------------------------
"6" is inbetween "48" and "12".
"34" is outside the two circles.
Dividing the first equation by 2
X + 2y = 12
Dividing the equation 2 by 4
-3x + 2y = -4
subtracting both equations
4x = 16
X = 4
Also 4 + 2y = 12
2y = 8
Y = 4

Answer:
f(-2) = 2
Step-by-step explanation:
The question is asking you to find the y value when the x value is -2. When observing the graph, we can see when the x value is -2, the y value is 2. Therefore, f(-2) = 2.
So for a tangent and a secant, you multiply x^2 (since it’s a tangent you square it) and test that equal to 6(6+12) so now you have x^2=6(6+12). solve for X to get sqrt(108) or 10.4
the equation is — tan^2=outside x whole thing
remember to ADD the entire secant (so add 6 plus 12) don’t multiply them (6x12)
x^2=6(6+12)
x^2=6(18) OR x^2=36+72
x^2=108
x=sqrt(108) OR x=10.4
