Which of the following is a linear function?

Rama09 [41]

$\boxed{ \textbf{ \huge{Answer: A}}}$

A linear function has 1 as the highest power of the variable.

A. f(x) = 2 - 7x

here, the highest power of the variable x is 1.
Hence it is a LINEAR function.
___________

B. f(x) = 2 + x + x^2

here, the highest power of the variable x is 2.
Hence it is NOT a linear function.
_______________

$c.f(x) = \sqrt{2 + 7x}$
here, the highest power of the variable x is 1/2.
Hence it is NOT a linear function.

Aneesha travels at a rate of 50 miles per hour. Morris is traveling 3 feet per second less than Aneesha. Which is the best estim

goldfiish [28.3K]

If Aneesha travels at a rate of
50 miles............................1h
and 1mile=5280ft, therefore 50 miles = 264000 ft
and 1 h =3600 seconds we can say that Aneesha travels

264,000 ft in 3600 seconds or
264,000/3600= 73.33 ft/s

Morris travels 3 ft per second less than her
so 73.33-3=70.33 ft/s for Morris

How can you use the Distributive Property to check your work when factoring? Once an expression has been factored, use the Distr

Mariana [72]

Answer:

Once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.

Step-by-step explanation:

The distributive property for any binary operation Ф under * in the given set S where a, b, c ∈ S

The binary operation a * (b Ф c) = (a * b) Ф (a * c) .

The operation * distributes over the operation Ф.

Now, when factoring, suppose we have an expression ab + ac. To factor this, we have a(b + c).

To check that our answer is correct, since the expression has been factored, we then distribute the multiplication over the addition to check if the factorization is correct.

So, a(b + c) = ab + ac which is our initial expression.

So, to use the distributive property to check work when factoring, once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.

on each of 3 days Derrick rode 6.45 km to school 150 meters to the library and then 500 meters back home. how many kilometers di

Alisiya [41]

1,969.35.
first you add them all up (6.45+150+500)=656.45, which is how much he rode in 1 day, no you multiply it by 3. so 3(656.45)=1,969.35 so thats how many km he rode in three days
