Hi there!

I believe your answer is:

(-2, 0)

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\text{Substitute in \textbf{0} for } y \text{ and solve for } x\text{.}\\-------------------\\y = 2x+4\\-------------------\\\rightarrow 0 = 2x +4\\\\\rightarrow 2x + 4 = 0\\\\\rightarrow 2x +4 - 4 = 0 - 4\\\\\rightarrow 2x = -4\\\\\rightarrow\frac{2x=-4}{2}\\\\\rightarrow \boxed{x=-2}$

⸻⸻⸻⸻

$\text{The \textbf{x-intercept} of the given equation is: } (-2, 0)$

⸻⸻⸻⸻

The correct option is B.

Step-by-step explanation:

It is given that Mrs. Ming invested an amount of money in two accounts for one year.She invested some at 8% interest and the rest at 6% interest. Her total amount invested was $1,500.

Let the amount invested in the account paying 6% be x. So, the amount invested in the account paying 8% is 1500-x.

Total interest earned by Ming is

$Interest=\frac{6x}{100}+\frac{8}{100}(1500-x)$
