Answer:
(0,b) from a formula y=mx+b
(0,y) from a graph
Step-by-step explanation:
The greatest common factor (GCF) of 21 and 84 is 21.
The GCF is the largest number by which both numbers can be divided. Between 21 and 84, it is 21 because 21/21=1 and 84/21=4.
Answer:
Supplementary to x is a 90° angle (right angle) which means that both x and the right angle will have to equal 180 degrees:
90 + x = 180
-90 -90
x = 90°
Let's find the angle measure that is supplementary to y.
A 5 sided shape is equal to 540 degrees (you could find this by using the formula: (n - 2) x 180 where n is the number of sides)
so given interior angles:
90 + 80 + 98(supplementary to angle 82 degrees) + 136 + 136(two equal angle measures in the polygon that are missing)
= 540(which is correct), so now we know the two missing angles, 136, besides the angle supplementary to 82 degrees.
136 is supplementary to y so:
136 + y = 180
-136 -136
y = 44°
The first one is C because on a coordinate plane is you count the number of spaces between them it’s 7 side to side( horizontal) and the second one is quadrant 2 because when reflecting across the y axis you move over the y axis which is why it’s quadrant 2. Hope this helps!
