1) the cost of a charm bracelet is $12 without the charms. There is an additional cost of $6 for each charm added to the bracele
Hitman42 [59]

The equation that could be used to find how many charms are on a bracelet that costs $96 will be:  12+6c=96  and they can buy 14 charms.

<em><u>Explanation</u></em>

The cost of a charm bracelet is $12 without the charms and the additional cost is $6 for each charm.

If the number of charms added to the bracelet is 'c' , then the <u>total additional cost for the charms</u> will be:  \$6c

Given that, the total cost of the bracelet with charms is $96.

So the equation will be:   12+6c=96

Now solving the above equation, we will get.....

12+6c=96\\ \\ 6c=96-12=84\\ \\ c=\frac{84}{6}=14

Thus, they can buy 14 charms.

Find the line of symmetry equation for the function f(x )=x −2x −3.
andriy [413]

Answer:

x = 1

Step-by-step explanation:

The line of symmetry is defined as the x value of the vertex of a parabola.

To find the vertex of a parabola, we need to convert to vertex form.

Vertex form looks like this:

y=a(x-h)^2+k, where -h is the x value of the vertex and k is the y value of the vertex.

H is also defined as \frac{-b}{2a} where a is the coefficient of x squared and b is the coefficient of the x term.

The coefficient of the x squared term is 1 and the coefficient of b is -2.

Plugging in, we get \frac{-(-2)}{2(1)}, which is equal to 1. This can then be plugged into the equation as

y=1(x-1)^2+k, but k doesn't matter because all we need is the x-term. Now, our x-term is negative h, which is negative negative one, which is positive one. Therefore, our answer is x = 1.

the temperature in november was less than 55 degrees every day which inequality shows the temperature in november
grin007 [14]

Answer:

a. x < 55

Step-by-step explanation:

We know that the temperature in November was less than 55° every single day, we are then asked to find which inequality out of the four given shows the temperature in November.

To do so, take the most crucial information, "the temperature in November was less than 55° every single day." The words "less than" makes us know that we will be using the sign "<". Looking at the answers, we see only one that uses it, and that is a.

Therefore a is the correct answer.
