Answer:
58/9
Step-by-step explanation:
5/3 +43/9
Lets take the L.C.M first
The L.C.M would be 9
Solve the term by taking 9 as L.C.M
=15+43/9
Add the numerator.
=58/9
The answer is 58/9 ....
The degree is 5, so the largest exponent of the polynomial is 5. This means the answer is either A or B. Choice C is ruled out because the degree here is 7. Choice D is ruled out because the degree here is 6
For choice A, the leading coefficient is 6. This is the number to the left of the variable term of the largest exponent. So we can rule out choice A (because the leading coefficient should be 7)
Choice B is the answer. It has a degree of 5 and a leading coefficient of 7 and also a constant term of 6. The constant term is simply the term without any variables attached to it.
Multiply both sides by any number you want. I'll pick 2
x = -3 turns into 2x = -6 after doing so
--------------------------
Add anything you want to both sides. I'll pick 7
x = -3 turns into x+7 = 4 after doing so
---------------------------
you can do a combination of both multiplication and addition, as long as you do the same thing to both sides. First I'll do multiplication. I'm going to multiply both sides by 2 first
x = -3 turns into 2x = -6
then I'm going to add 7 to both sides
2x = -6 turns into 2x+7 = 1
If you were to solve 2x+7 = -1, then you'd get to x = -3 again
As a check, replace x with -3 and we have...
2x+7 = 1
2(-3)+7 = 1
-6+7 = 1
1 = 1
we get a true statement, which helps confirm we have the right equation.
