90° clockwise rotation<br> Help please
maria [59]

Answer:

E' (-2,5)

F' (-3,1)

G' (-2,-1)

H' (0,3)

Step-by-step explanation:

The rule for 90 degree clockwise rotation is (h,k) -> (k,-h). This means flip the x-value's sign and then switch x and y's position. For example E (-5,-2), first flip x's sign (5,-2) and then switch x and y's places (-2,5).

+(-6) + (-8)= -4<br> What’s the missing number???
Darya [45]

Answer:

10

Step by step explanation:

In general, if we have an equation that has just one variable, such as x, then "solving the equation" means finding the set of all values that can be substituted for the one variable to produce a valid equation.

Isolate "x" on one side of the algebraic equation by adding the negative number that appears on the same side of the equation as the "x." For example, in the equation "x - 5 = 12", rewrite the equation as "x = 12 + 5" and solve for "x."

x + (-6) + (-8) = -4

x + (-6 + -8) = -4

x + (-14) = -4

x + (-14 + 14) = -4 + 14

x = 10

How do I find the slope of a perpendicular line?
Licemer1 [7]
Yes, math can be challenging sometimes (mostly due to the horrible way its taught by teachers but I wont go on a rant about that today).

The Slope of a parallel line is obviously going to have the same slope as the line it is parallel to, which you already know.

But for perpendicular, how would we figure that out?

First, you need to understand whats going on.  Picture a linear line.  Now, look at the (0,0) point.  To make it perpendicular, it must form 90 degrees with the other line.  Now, to get the answer for a perpendicular line, you need to remember two steps.

1.) Change the sign to the opposite sign (negative would go positive and positive would go negative)

2.) You take the reciprocal of the line (That is what times that number would make that number equal one.  2 * 1/2 would be 1.  You can also look at this by switching the denominator and numerator.
