The answer would be a. Yes, the student’s answer is reasonable.

In the problem, it states that Cindy rode her bike for an hour and ran for an hour.  Without the presence of the comma between rode her bike for an hour, and ran for an hour, this just means that Cindy only rode her bike and ran it for an hour.

The sentence can be written as Cindy rode her bike and ran for an hour.  So, this gives an answer that Cindy only exercise for an hour.

Ms. Cruz has a tank with 11 fish. After buying two more, she has 2 less than triple the amount of fish Ms. Montesinos has. How m
notka56 [123]

Answer:

a) The variable, M represents the amount of fish Ms. Montesinos has

b) The set equation is 11 + 2 = 3 × M - 2

c) 5

Step-by-step explanation:

The given parameters are;

The number of fishes in Ms. Cruz's tank = 11 fishes

The number of fishes Ms, Cruz has after buying two more fishes = 3 × The amount of fish Ms. Montesinos has - 2 fishes

a) Let the variable, M represent the amount of fish Ms. Montesinos has

b) The set up equation is as follows;

11 + 2 = 3 × M - 2

c) From the equation, 11 + 2 = 3 × M - 2, we have;

13 = 3·M - 2

3·M = 13 + 2 = 15

3·M = 15

M = 15/3 = 5

M = 5

The number of fishes Ms. Montesinos has is 17 fishes

F(x) = 7x
ziro4ka [17]

The parent function is given by f(x)= 7x

and the transformation function is given by g(x)= 7x + 6

We can see that, 6 has been added to the function f(x) to get the function g(x).

We know that when we add some constant 'c' in the function then the function gets shifted upward by 'c' units.

Therefore, we will get g(x), when we will shift f(x) upward by 6 units.

Both functions are linear function hence, the asymptote of g(x) is the asymptote of f(x) shifted six units up.

D is the correct option.

The length of a rectangle is (x^2- 4x+2) feet and the width is (x+4) feet
erastovalidia [21]

Answer:

A=x^3-14x+8

Step-by-step explanation:

Given that,

Length of a rectangle, l=(x^2- 4x+2)

Width of a rectangle, b=(x+4)

We need to find the area of the rectangle.

We know that,

Area of a rectangle = l × b

Substituting all the values,

A=(x^2- 4x+2)\times (x+4)\\\\=x^3+4x^2-4x^2-16x+2x+8\\\\=x^3-14x+8

Hence, the area of the rectangle is x^3-14x+8.
