Answer:
(2,5)
Step-by-step explanation:
The rule to 90 degrees about the origin is (x,y) to (-y,x). You basically switch the values of y and x but remember the value of y is negative. The value of y is -2 so -2 is now 2 since the rule changed the sign (-2×-y=2) and 5 isnt affected except it is the x value. Just know that since they r switched, x is now 2 and y is 5 when rotated 90 degrees about the origin.
Answer:
If the lines BC and DE are parallel, the value of c is c=-2
Step-by-step explanation:
We are given line segment BC with end points B(2, 2) and C(9,6) and line segment DE with endpoints D(c, -7) and E(5, -3).
Using slope formula: 
we can find point c
When 2 lines are parallel there slope is same.
So, Slope of line BC =Slope of Line DE
We have:
Putting values and finding c
So, If the lines BC and DE are parallel, the value of c is c=-2
Answer:
5/8
Step-by-step explanation:
12/17 is 0.70
5/8 is 0.62
However, 12/17 had a lot more numbers than that so

Answer:
(2,-10)
x=2
y= -10
Step-by-step explanation:
To solve by combining the equations we first need to get everything in linear form.
For both equations we can simply just add y to both sides and then subtract the other number on the right side. Doing this gets us
-2x-6=y
-7x+4=y
We then set the two equations equal to each other and solve for y
-2x-6= -7x+4
add 7x and 6 to both sides and get
5x=10
x=2
Use this x value and plug it into any equation
let's do it on the first
-2(2)-y=6
Solve for y and get
-y=10
which means that
y= -10
