Answer

Given expression,

(81x^2-25)\times \dfrac{6}{18x+10}

We have to find the value of x for which the expression is undefined.

Simplifying the given expression

((9x)^2-5^2)\times \dfrac{3}{9x+5}

(9x-5)(9x+5)\times \dfrac{3}{9x+5}

3(9x-5)

On solving we can see that the expression is defined for all value of x.

I spent 80% of my money and had $12 left. How much money did I have to start ?
xeze [42]
If you spent 80% that means you have 20% left, we'll use B as variable

20% x B = 12
0.20/0.20 x B = 12/0.20
B = 60

On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 3, negative 7) and (0, 2). Everyth
crimeas [40]

The inequality described can be written as:

y < 3x + 2.

<h3>How to get the inequality?</h3>

First, we know that we have a dashed line, and the region to the left of that line is shaded, then we will have:

y < line.

The linear equation is of the form:

y = a*x + b

Where a is the slope and b is the y-intercept.

Remember that if a line passes through the points (x₁, y₁) and (x₂, y₂), then the slope is:

a = \frac{y_2 - y_1}{x_2 - x_1}

Here we know that the line passes through (-3, -7) and (0, 2), so the slope is:

a = \frac{2 - (-7)}{0 - (-3)} = 9/3 = 3

And because the line passes through (0, 2), the y-intercept is 2, then the inequality is:

y < 3x + 2.
