905=5a
905/5=5a/5
181=a
HOPE THIS HELPS!!!!!!!!!!
To get this, take 0.10 x 145 = 14.5
Answer:
25/29
Step-by-step explanation:
see the attached picture.
Y= f(x)= ax+b
when x= -1, y= -1
-1= -a+b | * ( -1)
when x= -3, y=2
2= -3a+b
-3a+b= 2
a - b= 1
--------------
2a=3
a=3/2 is the slope
X = (15 - 8y)/9
-5[(15 - 8y)/9] + 12y = -107
(-75/9) + (40/9) + 12y = -107
y = -8.59
x = [15 - 8(-8.59)]/9
x = 9.3
(x,y) = (9.3, -8.59)
