R = x(a + b)
r = ax + bx
r - ax = bx
r - ax/x = b
b = r - ax/ x
Answer:
5+10n
Step-by-step explanation:
You multiply 1 to the 5, and then you multiply 2n to the 5. It's called the distribution property if you want to know more about it.
Answer:
impossible?
Step-by-step explanation:
<span>The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation.</span>
<span>So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation. And since x + y = 8, you are adding the same value to each side of the first equation.</span>
It's asking for a composition function where you insert the function g(x) into f(x).
f(g(x))=10(x+8)+25
f(g(x))=10x+80+25
f(g(x))=10x+105
