Answer:
2 (assuming equatin you meant was -2(3g - 2) - (4g + 3))
Step-by-step explanation:
-2(39 - 2) - (48 + 3)
-78+4-48-3
= - 125
(assuming that your equation instead is -2(3g - 2) - (4g + 3)
-6g+4-4g-3
-10g+1
For questions like this search up desmos graphing and put that equation in.
Since the function y= f(x) is decreasing on the interval (5, 7), y = -f(x) is INCREASING on the interval (5,7), because the slope is inverted due to the negative sign.
I have both of them, I hope this was what you were looking for ^.^
