Answers

Answer 1

Answer: $4s-12=-5s+51\ \ \ \ /+12\n\n4s-12+12=-5s+51+12\n\n4s=-5s+63\ \ \ /+5s\n\n4s+5s=-5s+5s+63\n\n9s=63\ \ \ /:9\n\n9s:9=63:9\n\ns=7$

Answer 2

Answer: 4s-12=-5s+51
+12= +12
4s=-5s+63
+5s =+5s
9s=63
9/9=63/9
s=7

What is the solution of x - 13 =5

Answers

If you're looking for x then it would be x=18 since you add 13 to both sides to have x alone

x-13=5
+13=+13
x =18
the answer is x=8

What does the fundamental theorem of algebra and its corollary tell you about the roots of the polynomial equation p(x)=0 where p(x) has degree n?

Answers

Answer:

A polynomial with complex coefficients of degree n has n complex roots, counted with multiplicity.

Step-by-step explanation:

We are given a polynomial p(x) in the question with degree n.

The degree n means the n is the highest power of variable in the given polynomial.

The equation:

$p(x) = 0$

Fundamental theorem of Algebra

The Fundamental theorem of Algebra states that a a polynomial of degree n will have n roots of the equation.

This can further be explained as:

A polynomial with complex coefficients of degree n has n complex roots, counted with multiplicity.

tom sold half of his comic books and then bought six more. he now has 12. how many did he begin with?

Answers

b=books
Sold half of book: b/2
Bought six more: b/2+
Now has 12: b/2+6=12
Subtract 6 on both sides: b/2+6-6=12-6
b/2=6
Multiply both sides by 2: b=12

Which of the following is a function equivalent to f(x) = 5(1.9)^3x? f(x) = 34.29^x
f(x) = 5(6.86x)
f(x) = 5(6.86)^x
f(x) = 328.51^x

Answers

Answer:

f(x) = 5(6.86)^x

Step-by-step explanation:

The function f(x) can be simplified according the the laws of mathematics. The expression is 5 multiplied by the 1.9^3x. You cannnot multiply 5 with 1.9 because 1.9 has a power of 3x. The 5 can only be multiply by the 1.9 if the 5 had a power of x or if 1.9 has a power of just 3. Therefore:

f(x) = 5×(1.9×1,9×1.9)^x = 5×(6.86)^x

1.9^3 = 6.86, so assuming it's 1.9^3 and not 1.9^(3x) then the answer is
f(x) = 5(6.86x)
Your question isn't 100% clear though.

What is the range of each function given below?
a. Let f(x) = 9x − 1.

Answers

Answer:

Range of f=R

Step-by-step explanation:

We are given that a function

$f(x)=9x-1$

We have to find the range of given function.

The given function is linear function because the degree of function is 1.

When the degree of function is 1 then the function is called the linear function.

The domain of linear function is a set of real numbers because it can be defined for all real values of x.

Domain of given function =R

When we substitute the real value of x in given function then we get a real number also.

Therefore, the range of f=R
