The slope-intercept equation is y=mx+b.

The slope formula is \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

Our three points are (5,5), (-5,-7) and (0,-1)

Using our slope formula our slope becomes \frac{-7-5}{-5-5} =\frac{12}{10} =\frac{6}{5}

Then, if we use one of our points (pick whichever you want, although (0,1) is the easiest) to solve the equation. So, y=\frac{6}{5}x-1. When we solve for x and y, we get -1=0+b, or b=-1.

When we plug that back into the equation, we gety=\frac{6}{5}x-1.

Graph the following inequality. Click on the graph until the correct one appears.
exis [7]

Answer:     Its the first one

You draw the graph of the line y=3x+5

but make the line dotted.

Label the line y>3x+5

Note that if instead we hade y≥3x+5 the line would be solid.

If you draw a line parallel to the y-axis through any x-value the value of y can be any on that vertical line that is above but not on the line y=3x+5

. So you end up with a 'feasible' region of solutions for y

What is the value of x in the triangle?<br> х<br> 30<br> 7V3<br> 60°
Hatshy [7]

Answer:

A. 21

Step-by-step explanation:

Use the trigonometric function for the tangent of an angle because the adjacent side of the right-angled triangle is provided in the question, whilst the opposite side is x.

tan = opposite / adjacent

tan 60° = x / 7 * sqrt(3)

Now make x the subject of the equation.

x = tan 60° * 7 * sqrt(3)

x = 21

When multiplying, take into consideration all the digits on your calculator display.

Hope this helped!
