Solve for n in the literal equation a(n-2)+5=bn

Helga [31]

Answer:

Answer is below

Step-by-step explanation:

a(n-2)+5=bn

Add -bn to both sides

an-2a+5+(-bn)=bn+(-bn)

an-bn-2a+5=0

add two a to both sides

an−bn−2a+5+(2a)=0+(2a)

an−bn+5=2a

Add -5 to both sides

an−bn+5+(-5)=2a+(-5)

an−bn=2a−5

Factor out our variable

n(a−b)=2a−5

Divide both sides by a-b

n(a-b)/a-b=2a-5/a-b

n=2a-5/a-b

Hope this helps

78. How can the polynomial, 18x^2 + 30x^6 be factored using the GCF?

dexar [7]

Answer:

6x^2(5x^4 +3)

Step-by-step explanation:

The greatest common factor of 18 = 3·6 and 30 = 5·6 is 6.

The greatest common factor of x^2 and x^6 is x^2.

Factoring 6x^2 from both terms, we get ...

... 18x^2 +30x^6 = 6x^2(3 +5x^4)

Comment on the question

Since this answer is not among the answer choices, I suggest you ask your teacher to demonstrate how this problem is worked.

It appears as though the answers go with the problem 18x^9 +30x^6. Maybe there's a typo somewhere. For that problem, the best choice is the 2nd answer.

If a=3 and b=4 then ba=

yuradex [85]

Answer:

Step-by-step explanation:

"ba" means "b * a", where * is multiplication. So, we want to find the product of a and b.

We know a = 3 and b = 4, so we just plug these in: 3 * 4 = 12.

Thus, ba = 12.

Hope this helps!

What are equivilant equations?how do you find them?

TEA [102]

Answer:

Equivalent equations are algebraic equations that have identical solutions or roots. you can find it by adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation as well as multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation.

2. Define the absolute value function, y = |x|, as a piecewise function. Please include complete sentences and examples to justi

Mekhanik [1.2K]

Y = |x| = x if x ≥ 0, -x if x < 0

absolute value can be interpreted as a function that does not allow negative real numbers, forcing them to be positive (leaving 0 alone). if the input x is more than or equal 0, then x stays positive so there is no need to do anything: "x if x ≥ 0".
if the input is less than 0, then it is an negative number and needs a negative coefficient to negate the negative: "-x if x < 0"

example: if x = -3, then it will take the "-x if x < 0" piece resulting in y = -(-3) = 3, which is what |-3| does

if x = 1, it will take the "x if x ≥ 0" piece and just have y = 1 which is what |1| does.

for x = 0, it will take the "x if x ≥ 0" and just have y = 0 which is what |0| does
