True of false:There is always one solution of a system of linear equations.

When we’re writing, we can use a thesaurus to find a different word with the same meaning to present an idea. How can we find di

Pavlova-9 [17]

Answer:

Math has the particularity that it is a logical construction.

This means that we can start with an expression X (where X is an equation, not a variable)

Now we can apply a lot of "math" to this equation in such a way that we can rewrite it, but the actual "meaning" of the equation will not change.

An example of this is factoring.

For example, we can write a quadratic equation as:

a*x^2 + b*x + c.

And we also can write this as:

n*(x - k)*(x - j)

where k and j are the solutions of the equation:

a*x^2 + b*x + c = 0.

What is the advantage of writing the equation in each form?

Well, both expressions actually represent the same thing, but the explicit information in each expression is different, so depending on what we want to do, we will choose one option or the other.

And we have lot's of different ways to express something, where we can find some ones really complex and useful, like the series of Taylor, where we can write a function as a summation of infinite terms.

What is the quotient?

Ierofanga [76]

Answer:

3/2

Step-by-step explanation:

For dividing rational expressions such as the one given, we use the same concept that we use when dividing fractions.

Thus, we multiply the first expression with the second expression's reciprocal as shown below.

$\frac{2m + 4}{8} \div \frac{m + 2}{6}$

$\frac{2(m + 2)}{8} \times \frac{6}{m + 2}$

We can cancel common factors and simplify the product. Hence, we have

$\frac{2(6)}{8}$

$\frac{3}{2}$

Therefore, the quotient of the expressions is equal to 3/2.

A baseball team has home games on Friday and Sunday. The two games together earn $3532.50 for the team. Friday's game generate

Semmy [17]

First you would divide $3532.50 by 2 which would equal $1766.25.
The you would add $225.75 to $1766.25 which equals $1982.
The Friday had $1540.50 taken in & the Sunday game had $1982 taken in.

The triangles below are similar. Triangle Y X Z. Side Y X is 6 centimeters, X Z is 7 centimeters, and Z Y is 3 centimeters. Tria

zavuch27 [327]

Answer:

(c) Triangle Z Y X is similar to triangle C B A

Step-by-step explanation:

Triangles are similar when corresponding sides have the same ratio. Corresponding sides will have corresponding end point vertices. The similarity statement lists corresponding vertices in the same order.

__

<h3>corresponding sides</h3>

The side lengths, smallest to largest, for the two triangles are ...

3 cm -- ZY
6 cm -- YX
7 cm -- XZ

And for the other triangle, ...

6 cm -- BC
12 cm -- AB
14 cm -- AC

<h3>corresponding vertices</h3>

The points joining the each side to the next one longer, in order for the two triangles, are ...

Y, X, Z and B, A, C

The vertices corresponding to ZYX in the same order are CBA.

triangle ZYX is similar to triangle CBA
