Answer:
B
Step-by-step explanation:
So, for five cups of water, you need one cup of sugar. 1s=5w.
Now, you divide both sides by five.
1/5s=1/w
For this case we have the following function:
By power properties we can rewrite the function as follows:
We have then:
Then rewriting the function we have:
Answer:
an equivalent function to 
is:
Answer: 16. f(1)=-2
17. f(-3)=1
18. x=0
19. x=-1 and x=1
Step-by-step explanation:
16. f(1)=-2
17. f(-3)=1
18. f(x)=-3
x=0 ==> f(0)=-3
19. f(x)=-2
x=-1 and x=1 ==> f(-1)=-2, f(1)=-2
Both of these have the same number of solutions (which is 2)
Remember that |5x + 6| means "the absolute value of the expression '5x + 6'", so in this case, 5x + 6 could equal 41 or -41 since the absolute value would "strip away" the positive or negative sign and leave just the number
So, if you solve:
5x + 6 = 41
5x = 41 - 6 = 35
x = 35 / 5 = 7
5x + 6 = -41
5x = -41 - 6
5x = -47
x = -47 / 5
Do the same thing for the other expression:
2x + 13 = 28
2x = 28 - 13 = 15
x = 15 / 2
2x + 13 = -28
2x = -28 - 13
2x = -41
x = -41 / 2
So, both of these expressions have two solutions.
Hope this helps!
Good luck.
Answer:
no solution
Step-by-step explanation:
If you divide the first equation by 2 you get:
2x+2y=4 (first equation after dividing both sides by 2)
2x+2y=-4 (second equation)
This is setup for elimination.
Subtract the equations:
2x+2y=4
2x+2y=-4
--------------Subtracting!
0+0=8
0=8
0=8 is a false equation which implies the system has no solution.
