Answer:
x + 5 = -3
x=-10
- -2x -4 +8x -12
2(3x - 8)
Step-by-step explanation:
1-
Multiply both sides of the equation by 5: 4x + 25 = -15
Move the constant to the right-hand side and change its sign : 4x = -15 - 25
Calculate the diffrerence: 4x = -40
Divide both sides of the equation by 4 : x= -10
2-
Collect like terms: 6x-4-12
Factor out 2 from the expression : 2(3x - 8)
Let's see.
We have function . We have to determine if the function is even or odd or neither.
We can find this out in many ways but the assignment specifically asks to prove this algebraically.
Function is even if , so,
Which is true since negative raised to an even power is positive to that same number.
Similarly, function is odd if , that is,
.
So we have prooved that function is an even function not an odd function and therefore also not neither.
Hope this helps.
