Option C
For x = 1.5 we get f(x) = -2
<em><u>Solution:</u></em>
Given function is:
We have to find the value of "x" so that f(x) = -2
Substitute f(x) = -2 in given function
Solve for "x" by moving the constants to one side and variables to other side
For x = 1.5 we get f(x) = -2
We can verify by substituting x = 1.5 in given function
Thus for x = 1.5 we get f(x) = -2

Answer:
(x, y) = (-11, 4)
Step-by-step explanation:
You can subtract 3 times the second equation from the first to eliminate y.
(7x +9y) -3(x +3y) = (-41) -3(1)
4x = -44
x = -11
Substituting into the second equation gives ...
-11 +3y = 1
3y = 12
y = 4
The solution is (x, y) = (-11, 4).
This composite figure consists of a right triangle and semicircle
The area of a triangle is: 1/2(bh)
The area of a semicircle is 1/2(pi)(r²)
Plug in the values:
1/2( 12)(8)
=48
1/2(3.14)(4²)
=25.12
25.12+48=73.12
Hope this helped :)
