Answer:
y=mx+b
Step-by-step explanation:
Answer:
^algebra^
#1). a - b=4
a=4 + b .....(equation 1)
#2) a + b=12
(4 + b) + b= 12
4 + b + b=12
4 + 2b=12
2b= 12 - 4
2b =8
b= 8:2
b=4
subtituted b in equation 1
a= 4 + b
a= 4 + 4
a=8
so, the number is 8 and 4
Answer:
A
Step-by-step explanation:
Because each value of x maps onto only one value of y, it is a function.
However, because it is not the graph of a line, it is a nonlinear function.
(_ , _) means (X , Y)
(25 , ) means
X = 25 then you need find the value of Y from the equation .

so the first answer is (25,-3)
..............
( , -8) means
Y = -8 then you need to find the value of X from the equation .

so the second answer is ( 0 , -8 )
