Answer:
-12.75 , -22
Step-by-step explanation:
8x - 6y = 30
8x = 30 + 6y
-20 - 16x + 7y = 30
-2(30 + 6y) + 7y = 50
-5y = 50+60
y = -22
7x = 30 - 6(22) = -102
x = -12.75
The equation of the given circle is :
(x - 3) + (y - 5) = 8
where, r² = 8
therefore, value of radius (r) = units
Answer:4.8 +0.5 x
Step-by-step explanation:
Answer:
22
Step-by-step explanation:
180 is a straight line to minus 77 equals 103 degrees left.
Subtract 15 from 103 to get 88.
now to get x from 4x you divide 88 with 4 to get...
x = 22
Answer:
P = 3x + 7
Step-by-step explanation:
The perimeter (P) is the sum of the 3 sides of the triangle, that is
P = x + 5 + x + 4 + x - 2 ← collect like terms
= 3x + 7
