Keep in mind both of these angles are equal to each other meaning the equation will have a = So...
4x+7=5(x-4)
Now multiply 5 to x and 4
4x+7=5x-20
Now subtract 4x from 5x
7=1x-20
Now add 20 to both sides
27=x
So x=27
The middle point of BC is (0,2), the midpoint of CD is (1,0)
to prove two lines are parallel, prove their slopes are the same.
slope of BD: m=rise/run=4/-2=-2 (the run is negative because to get to B from D on the grid, you have to move from right to left, then upward. If the horizontal move is from left to right, the run is positive)
slope of EG: m=rise/run=2/-1=-2
EG and BD have the same slope, so they are parallel.
Answer:
integer = 5
rational number but not an integer - 3 and a 1/2
irrational number - it's the one with 11
Answer:
(x+3)^2 +(y-5)^2 = 36
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2 +(y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x- -3)^2 +(y-5)^2 = 6^2
(x+3)^2 +(y-5)^2 = 36
