Plug in the 6 and -1 to get the answers
f(6)=120
f(-1)= 8
Answer:
x= 5/4
Step-by-step explanation:
isolate the variable by dividing each side by factors that don't contain x.
-3--4 =
-3 + 4 =
1
(Two negatives make a positive)
Answer: 1
28. 1.45l ÷ 0.32l = 4.53125
so approximately 5 glasses to leave the bottle empty
29. 5.6kg + 2.5kg = 8.1kg
8.1kg ÷ 0.48 = 16.875
he can make 16 complete doughs
there will be 0.875kg of flour left
Answer:

Step-by-step explanation:
The system we have:

we can solve the system by eliminating one of the variables, I will eliminate the 'y' variable by substracting the equations:

we have
which is zero, so now we have an equation that only depends on 'x'.
so now solving the resulting equation for 'x'

we have the value for x. Now we substitute this in the first of the original equations of the system to find the value of y:

thus, the solution of the system is:
