81/7= 81 over 7, or 11.6
Answer:
(12, 48 )
Step-by-step explanation:
Given the 2 equations
y = 5x - 12 → (1)
y = 3x + 12 → (2)
Substitute y = 5x - 12 into (2)
5x - 12 = 3x + 12 ( subtract 3x from both sides )
2x - 12 = 12 ( add 12 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12
Substitute x = 12 into either of the 2 equations and evaluate for y
Substituting into (2)
y = 3(12) + 12 = 36 + 12 = 48
solution is (12, 48 )
Answer:
y= -0.3x - 5.6
Step-by-step explanation:
m= (-5)-(-8)/(-2)-8
m= -0.3
y=mx+c
-8= -0.3(8)+c
-8= -2.4 +c
-8+2.4=c
c= -28/5
y= -0.3x - 5.6
