When I think of a number, double it, then add 7, I get 25. What number did I think of? ( Hint: Let the number be x)o
vivado [14]

Hey there!

The answer is 9

We will start by forming an equation to solve this.

So we are starting with a number, x, then doubling it and adding 7, which gives us 25.

So:

2x+7=25

Now we solve this equation:

2x+7=25

2x=18

x=9

Have a super awesome day!

What is the equation of the line below?
Licemer1 [7]

Answer:

y = -\frac{2}{3}x + 1

Step-by-step explanation:

The equation of the line shown can be expressed in the slope-intercept formula as y = mx + b

Let's find m = slope, and b = y-intercept.

Using two points on the line, (0, 1) and (1½, 0),

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 - 1}{\frac{3}{2} - 0} = \frac{-1}{\frac{3}{2}} = - \frac{2}{3}

y-intercept, b is where the line intercepts the y-axis = 1.

To create an equation for the line, substitute m = -⅔, b = 1 in y = mx + b.

✅The equation would be:

y = -\frac{2}{3}x + 1
