-18 + x = -11
Let's add 18 to both sides
x = 7
First you would need to Simplify <span>{3}^{2}<span>3<span>2</span></span></span> to <span>99
Next you would need to : </span>Use Negative Power Rule =9÷31
<span>
then you would need to use a ÷ b/c = a * c/b and get 9*3
And you will lastly get 27</span>
Answer:
Slope = 2
Step-by-step explanation:
Slope = 20/10 = 2
Answer:
It's 50 percent right
Step-by-step explanation:
there are many colors and they could all be different
Use the 2 points to find the gradient of the line
Gradient = (y - y1)/(x - x1), y and y1 are the two different y values.
(2.3 - - 7.4)/(-4.3 - 1.3) = -97/56 = -1.732
Note: y and x both come from the same coordinate, and y1 and x1 also come from the same coordinates - (x , y), (x1 , y1)
Use the following to find the equation (x, x1, y, and y1 are not the same as the first part)
y - y1 = m(x - x1)
Where x2 and y2 is an intersection (one of the coordinates you used) and m is the gradient you found.
So...
y - 2.3 = -1.732(x - - 4.3)
You can simplify this if you are required to.
