Which algebraic expression represents “Marcus ran four times as far this week”? 4 + n 4n n – 4

Mathematics

Answer:

The Answer would be 4n

Step-by-step explanation:

Since Marcus ran four times as far this week, we need to know how far he ran last week in order to solve this expression. Since we do not know this information it becomes our variable (n). From the statement we can also infer that there is multiplication since he states the word "times". Therefore our Algebraic Expression would be the following.

P = 4n

P being distance ran by Marcus, and n being distance ran last week by Marcus.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Plot the axis of symmetry and the vertex for this function: h(x) = (x − 5)2 − 7.
jeka94

Answer:

The vertex and the axis of symmetry in the attached figure

Step-by-step explanation:

we know that

The equation of a vertical parabola written in vertex form is equal to

f(x)=a(x-h)^2+k

where

a is the leading coefficient

(h,k) is the vertex of the parabola

and the equation of the axis of symmetry is equal to the x-coordinate of the vertex

x=h

In this problem

we have

h(x)=(x-5)^2-7

This is a vertical parabola written in vertex form open upward

The vertex is a minimum

where

the vertex is the point (5,-7)

the x-coordinate of the vertex is 5

so

the equation of the axis of symmetry is equal to

x=5

Harlamova29_29 [7]
x=660(1.1)^{t}

x represents the new value.

This multiplies 660, the starting value, by 110% for each year (t).

Find (f/g) (x) for the functions provided: ƒ(x) = x3 − 27, g(x) = 3x − 9
AnnZ [28]

Answer:

(\frac{f}{g})(x)=\frac{1}{3}(x^2+3x+9)

Step-by-step explanation:

We have been given that

f(x)=x^3-27,g(x)=3x-9

We can use the formula for difference of cubes to simplify the function f(x)

difference of cubes -  a^3-b^3=(a-b)(a^2+ab+b^2)

f(x)=x^3-27\\\\=x^3-3^3\\\\=(x-3)(x^2+3x+9)

And g(x) can be written as

g(x)=3x-9\\=3(x-3)

Thus, we have

(\frac{f}{g})(x)=\frac{(x-3)(x^2+3x+9)}{3(x-3}

On cancelling the common factors, we get

(\frac{f}{g})(x)=\frac{1}{3}(x^2+3x+9)
