Answer:
c) -20x^2+14x+12
all real numbers
Step-by-step explanation:
So (fg)(x)=f(x)g(x)=(-4x-2)(5x-6).
Need find the expression in standard form we need to use foil:
First: (-4x)(5x)=-20x^2
Outer: (-4x)(-6)=24x
Inner: (-2)(5x)=-10x
Last: (-2)(-6)=12
--------------------------Add like terms:
-20x^2+14x+12
Polynomials have domain all real numbers.
There are no restrictions on what x can be. For every number you plug in, you will get a number back.
Answer:
a 1 = 10
a 2 = 10 * 1/5 = 2
a 3 = 2 * 1/5 = 2/5
a 4 = 2/5 * 1/5 = 2/25
a 5 = 2/25 * 1/5 = 2/125
S 5 = a 1 + a 2 + a 3 +a 4 + a 5= 10 + 2 + 2/5 + 2/25 + 2/125 =
= 1250/125 + 250/125 + 50/125 + 10/125 + 2/125 = <u> 1562 / 125</u>
It would be 10500. Round the 450 to 500
Skippy should invest $ 7500 in account offering 4 % interest and $ 2500 in account offering 8 % simple interest
<em><u>Solution:</u></em>
Given that Skippy has a total of $10,000 to split between two investments
One account offers 4% simple interest, and the other account offers 8% simple interest
Total interest earned = 500
Number of years = 1
Let the principal with rate of interest 4 % is x
So the principal for rate of interest 8 % is 10000 - x
Total interest earned = simple interest for 4 % interest + simple interest for 8 % interest
Simple interest is given as:

Where "p" is the principal and "r" is the rate of interest and "n" is the number of years
Therefore,


Therefore skippy should invest $ 7500 in account offering 4 % interest
And skippy should invest (10000 - x) = (10000 - 7500) = $ 2500 in account offering 8 % interest
Answer:
like terms are terms that have the same variable
Step-by-step explanation:
when combining like terms we add their coefficients for example 4x + 5x = (4+5)x=9x
