Answer:
5x^4+ 2x^3+3x² – 3x + 2
Step-by-step explanation:
(5x^4+ 2x^3– 1)+(3x² – 3x + 3)
Combine like terms
5x^4+ 2x^3+3x² – 3x + 3– 1
The only like terms are the constants
5x^4+ 2x^3+3x² – 3x + 2
Answer:
x = -2
x= -3
Step-by-step explanation:
x 2+5x+6=0
To solve the equation, factor x^2+5x+6 using formula x^2+(a+b)x+ab=(x+a)(x+b). To find a and b, set up a system to be solved.
a+b=5
ab=6
Since ab is positive, a and b have the same sign. Since a+b is positive, a and b are both positive. List all such integer pairs that give product 6.
1,6
2,3
Calculate the sum for each pair.
1+6=7
2+3=5
The solution is the pair that gives sum 5.
a=2
b=3
Rewrite factored expression (x+a)(x+b) using the obtained values.
(x+2)(x+3)
To find equation solutions, solve x+2=0 and x+3=0.
x=−2
x=−3
Answer: SECOND OPTION
Step-by-step explanation:
Substitute any value of <em>n</em> shown in the table attached into each function given in the options, and observe if you obtain the value of 
shown in the table.
Let's substitute n=1 (According to the table, you need to obtain 
):
<u>For the first option:</u>
<u>For the second option:</u>
THIS IS THE FUNCTION
<u>For the third option:</u>
<u>For the fourth option:</u>
Therefore, the answer is the second option.
I don't really understand what you're asking, but say you have the number 67,to find 23% of that number, you would multiply 67 by .23, you will then get whatever 23% of 67 is.
Y = x + 5....so we sub in x + 5 for y in the other equation
4x + y = 20
4x + x + 5 = 20
5x + 5 = 20
5x = 20 - 5
5x = 15
x = 15/5
x = 3
y = x + 5
y = 3 + 5
y = 8
solution is (3,8)
