Answer:
37 1/2
Step-by-step explanation:
multiply the two numbers if their is an “of” in the statement
31 is the answer because if you add all the numbers and then divide by the number of
Answer:
y = -6
x = 1
Step-by-step explanation:
-x + 2y = -13
-x - 2y = 11
Sum the equations:
-x -x = -2x
+2y - 2y = 0
-13 + 11 = -2
then
-2x = -2
x = -2/-2
x = 1
from the first eq.
-x + 2y = -13
-1 + 2y = -13
2y = -13 + 1
2y = -12
y = -12/2
y = -6
check:
from the second eq.
-x -2y = 11
-1 -(2*-6) = 11
-1 -(-12) = 11
-1 + 12 = 11
Answer:
7/2
Step-by-step explanation:
Answer:m=-6/5
Step-by-step explanation: To figure this out you need to use the slope formula.
m=y2-y1/x2-x1
m=-17-1/17-2
m=-18/15
This Can then be reduced to m=-6/5
