Step-by-step explanation:

The required range is [0,∞]

All values, or inputs, constitute a function's domain, while all values, or outputs, constitute its range.

When examining a graph, the range of the function is from up to down, and the domain refers to all of the values on the graph from right to left.

The height of the cedars when they were planted by André, found using the formulas for arithmetic progression is 1.32 meters

An arithmetic progression is a number sequence that consists of numbers that have a constant or common difference between consecutive term of the sequence.

The year André planted the cedar hedge tree = 15 years ago

The present height of the hedge = 3 meters = 300 cm

The average rate at which the cedars grew = 12 cm per year

The height of the cedar hedge when André initially planted the them can be found by representing the situation using an arithmetic progression formula or as follows;

The nth term of an arithmetic progression, aₙ, can be found using the formula; aₙ = a₁ + (n - 1)·d

Where;

a₁ = The initial height of the tree

d = The amount the tree grows each year = 12 cm

n = The number of years ago, the tree was planted

When n = 15, we get;

a₁₅ = 3 meters = 300 cm

Therefore;

300 = a₁ + (15 - 1) × 12

a₁ = 300 - (15 - 1) × 12 = 132

Answer: 2 and 2/3

Step-by-step explanation: To divide these mixed numbers, I would first rewrite them as improper fractions.

You should be familiar with how do this and if you aren't, send me a comment below and I can give you a quick review.

So 5 and 2/3 becomes 17/3 and 2 and 1/8 becomes 17/8.

This gives us 17/3 ÷ 17/8.

When we divide fractions, we just change the division sign

to multiplication and take the reciprocal (flip) the second fraction.

So we have 17/3 · 8/17.

before multiplying, we can cross-cancel the 17's by dividing by their greatest common factor of 17 to get 1.

So we have 1/3 · 8/1 which is 8/3.

Now since 3 goes into 8 twice, our we have 2 as our whole fraction.

Since there is 2/3 left over, we have a fraction of 2/3.

So our final answer is 2 and 2/3.

The equation that can be used to find x is

3x + 6 = 2x + 9

Option E is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Lydia started with 6 charms and bought 3 more packs.

Claudia started with 9 charms and bought 2 more packs.

If each pack had x charms.

This can be written as,

Lydia:

Number of charms = 6 + 3x

Claudia:

Number of charms = 9 + 2x

Now,

Lydia and Claudia have the same number of charms in their collections.

This can be written as,

6 + 3x = 9 + 2x

3x + 6 = 2x + 9

Thus,

A graph is symmetric with respect to the y-axis if for every point (a, b) on the graph, there is also a point (-a, b) on the graph.

Linear functions are not symmetric with respect to the y-axis.

Quadratic functions are symmetric with respect to the y-axis if the y-axis is their axis of symmetry, so when the variable x is squared.

Cubic functions are not symmetric about the y-axis.

Square root functions are not symmetric about the y-axis.

There are two quadratic functions with x² in the given answer options.

Test to see if they are symmetric with respect to the y-axis.

Test for symmetry

To determine if a graph is symmetric with respect to the y-axis, replace all the x's with (−x).  If the resultant expression is equivalent to the original expression, the graph is symmetric with respect to the y-axis.

Given function:

[tex]y=-6x^2[/tex]

Replace x with (-x):

[tex]\implies y=-6(-x)^2[/tex]

[tex]\implies y=-6x^2[/tex]

Therefore, as the function is equal to the original function, this function is symmetric with respect to the y-axis.

Given function:

[tex]y=4x^2-2[/tex]

Replace y with (-y) and x with (-x):

[tex]\implies y=4(-x)^2-2[/tex]

[tex]\implies y=4x^2-2[/tex]

Therefore, as the function is equal to the original function, this function is symmetric with respect to the y-axis.

Luke and Cade have started running

Luke runs 15 more miles than thrice of that of number of miles Cade runs

Since we don't know the number of miles run by Cade

Let us assume that Cade runs x miles

In Mathematics, a transformation can be defined as the movement of a point from its original (initial) position to a final (new) location. This ultimately implies that, when an object is transformed, all of its points would be transformed as well.

Based on the transformation rule (x, y) → (-y, -x), we can reasonably infer and logically deduce that it represents or models a rotation of the geometric shape, followed by a reflection, which both preserves distance and angle measure based on these transformation rules:
