Answer:

The correct option is D) Infinitely many.

Step-by-step explanation:

Consider the provided graph.

The system of equation has the solution at the point where the line intersects.

Now consider the graph of the equation 2x = 2y-6 and y = x+3

By observing the graph it can be concluded that the graph of 2x = 2y-6 and y = x+3 has the same line.

A system of equation have infinitely many solutions if each equations refers to the same line.

Since 2x = 2y-6 and y = x+3 refer the same line. The system has infinitely many solutions.

Hence, the correct option is D) Infinitely many.

If 45% of a number n is 225 what is 75% of n

Tpy6a [65]

75% of n is 375.

Step-by-step explanation:

Given,

45% of a number n = 225

We will find n first.

$\frac{45}{100}n=225\\0.45n=225$

Dividing both sides by 0.45

$\frac{0.45n}{0.45}=\frac{225}{0.45}\\n=500$

Now we have to find 75% of n.

75% of n = $\frac{75}{100}*500=75*5$

75% of n = 375

75% of n is 375.

What is the product PLEASE HELP

Answer:

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

- 2x(- 4x - 3) - 9y²(- 4x - 3) ← distribute both parenthesis

= 8x² + 6x + 36xy² + 27y² → C

What is the solution to this system of equations? -5.9 x-3.7 y = -2.1. 5.9 x + 3.7 y = 2.1. a. (0, Negative 2.1) b.(0, 2.1) c. i

fenix001 [56]

Assuming your system of equations is

$\begin{cases}-5.9 x-3.7 y = -2.1\\ 5.9 x + 3.7 y = 2.1\end{cases}$

The answer is C. Infinitely many solutions. If my assumption is incorrect, then the answer will be likely different.

The reason why it's "infinitely many solutions" is because the first equation is the same as the second equation. The only difference is that everything was multiplied by -1. You could say that both sides were multiplied by -1.

Both equations given graph out the same line. They overlap perfectly yielding infinitely many solution points on the line.
