Answer: r=-7/6y+7/2
Step-by-step explanation:
Step 1: Add -5 to both sides.
6r+5+−5=−7y+26+−5
6r=−7y+21
Step 2: Divide both sides by 6.
6r/6=-7y+21/6
Let A be the angle of 79 degrees
B be the angle of (5y-4) degrees
C be the angle of (x+5) degrees
D be the angle of (9z-7) degrees
According to the property of parallelogram
Opposite angles are equal
We get, angle A = angle C
Since angle A = 79 degrees
And angle C = (x+5) degrees
We get, x+5=79
=> x=79-5=74.
Angle B = Angle D
(5y-4)=(9z-7)
Since there’s two variables here, we can’t use the property of “opposite angles are equivalent”
We have to use another property which is adjacent angles are equal
Therefore, we can find angle D
Angle D + Angle A=180
=> 9z-7 =180-79
z=108/9
z=12
Since (5y-4)=(9z-7)
Substitute z=12 in
We get, 5y-4=101
y= 105/5
y= 21
Therefore, x=74, y=21 and z=12.
Answer:
When it crosses y-axis it means that x coordinate must be 0 so let substitute 0 to x, y=5-2*0
So coordinates are [0,5]
(y-14)(y+14). You just square root 196
not sure your question?
comment then i can edit my answer XD
