The degree is 5, so the largest exponent of the polynomial is 5. This means the answer is either A or B. Choice C is ruled out because the degree here is 7. Choice D is ruled out because the degree here is 6
For choice A, the leading coefficient is 6. This is the number to the left of the variable term of the largest exponent. So we can rule out choice A (because the leading coefficient should be 7)
Choice B is the answer. It has a degree of 5 and a leading coefficient of 7 and also a constant term of 6. The constant term is simply the term without any variables attached to it.
B, because 40 and 40 make 80 and 180-80=100<span />
First, you want to find out how many kilometers are in one mile. So you take the information you are given and divide 16 km by 10 and you get 1.6 km/1mi. Now, you know that the distance between the two towns is 45 miles, so simply multiply 1.6 by 45 to get 67.5 km in 45 mi.
Answer:
k=3+6x
Step-by-step explanation:
the question says that k is an expression where x is a variable soo...
rewrite the given expressio with bases of 3
27×9^3x = 3k
3^3 × 3^2(3x) = 3k
Rule of exponent says that equal when you multiple you add exponent. Another rule says that equal bases cancel
3^6x+3 =3^k
6x+3=k
Hint: take the derivative of the function. then examine how many zeros that function can have, namely the max number of real zeros. that will be your answer.
