To solve for f, you need to isolate/get the variable by itself in the equation:
4(0.5f - 0.25) = 6 + f Distribute 4 into (0.5f - 0.25)
(4)0.5f + (4)(-0.25) = 6 + f
2f - 1 = 6 + f Subtract f on both sides to get "f" on one side of the equation
2f - f - 1 = 6 + f - f
f - 1 = 6 Add 1 on both sides to get "f" by itself
f - 1 + 1 = 6 + 1
f = 7
PROOF
4(0.5f - 0.25) = 6 + f Substitute/plug in 7 into "f" since f = 7
4(0.5(7) - 0.25) = 6 + 7
4(3.5 - 0.25) = 13
4(3.25) = 13
13 = 13
Answer:
1. 1
2. -3
3. yes
4. no, it is not, because the function stop at point (-6, -2)
5. -2
Answer:
Possible
Step-by-step explanation:
Hello
First you have to remove your parenthesis and since there is a “+” in front of the parenthesis, the expressions remain the same. So:
9.88+6.7-x = 2,6
Now, you have to add the numbers. So:
16.58-x = 2,6
Next, you have to move the constant (x) to the right and change its sign since it changes side. So:
-x = 2,6-16,58
Now, calculate the difference:
-x = 13,98
And lastly, change the signs on both sides of the equation since - + - equals +. So:
x = 13,98
Hope you found this helpful
Have a good day
