Answer:
(-7, -8)
Step-by-step explanation:
To start we have to isolate a variable to get an equation for it.
Let's get an equation for x from the first equation:
x - 2y = 9
x = 2y + 9
Now that we know what x is in terms of y, lets plug it into our second equation:
3(2y + 9) - 5y = 19
6y + 27 - 5y = 19
y + 27 = 19
y = -8
Now that we know what y equals, let's plug it into our first equation and solve for x:
x - 2(-8) = 9
x + 16 = 9
x = -7
Now that we have x and y, we make our ordered pair, in terms of (x, y):
(-7, -8)

Answer: none of them is right, did you meant maximum 4 and minimum 2?
Step-by-step explanation: cos x gets values between 1 and -1.
If you add 3 you get values between 4 and 2.
Your answer is C;You have a parabola. The range is all of your y's, and if you graph the parabola, you will see that the parabola opens downwards (hence the negative in front of the x) and no points ever go above 1 on the y-axis. Therefore all your y's are equal to or lower than 1, making your answer C. Hope this helps!
