C.the height of a student and the the day of a month a student was born
Answer:
rearrange them properly to get
x-y=7
-3x+y=12
( by elimination method)
x-y = 7
-3x+y=
(x+ –3x) + (–y+y) = (7+12)
-2x+0= 19
x= -9.5
from eqn(i)
x-y=7
-9.5 - y=7
-y=16.5
y= -16.5
Answer:
42
Step-by-step explanation:
we could use inverse operation and multiply 7 by 6
Answer:
It’s y2-y1 over x2-x1
Y2 is 5 and y1 is 5
5-5
X2 is 7 and x1 is -2
7- negative 2
5-5 is 0
7- negative 2 is 9
Slope is 0
Step-by-step explanation:
Hope this helps:)
Answer:
the answer would be p= -4
13-3p = -5(3+2p)
13-3p = -15-10p
13 = -15-7p
28 = -7p
p = -4
