Answer:
B) AB is parallel to CD, but AD is not parallel to BC.
Step-by-step explanation:
The options are:
A) AD is parallel to BC, but AB is not parallel to CD.
B) AB is parallel to CD, but AD is not parallel to BC.
C) AB is parallel to CD, and AD is parallel to BC.
D) AD is not parallel to BC, and AB is not parallel to CD.
AB and CD have the same slope, so they are parallel.
BC and AD have different slopes, so they are not parallel.
Therefore, the answer is B.
Answer:
Vertex is (4,1)
Step-by-step explanation:
x=-b/2a so you need to first divide the b (second term) by the a (first term) so you should get 1 as your new a and -8 as your new b. Negative (-8) is just 8 then divide that by 2(1) which is just 2 which equals 4. That is your x. To find your y, you plug your x back into the original equation and then solve it. Hope this helps!
Answer:
DGF=226
Step-by-step explanation:
Angle 113 is a inscribed angle since two it is on the exterior of the circle. We can find the central angle by multiply 2 by 113.
113×2=226
Since the central angle measure 226, that means the arc DGF measures 226 degrees.
DGF=113
Answer:
Albany
Step-by-step explanation:
We assume the two numbers are x and (x+1)
so x^2+(x+1)^2=421
x^2+(x^2+2x+1)=421
2x^2+2x-420=0
According to the formula of quadratic
x=14 or-15
cuz we know the two numbers are integers
so x=14
therefore the other number is 15
To make sure that's correct
14^2+15^2=421
Hope that helps you!!
