Answer:
y=4,x=1
Step-by-step explanation:
4x+y=8
x+y=5
subtract equation 2 from equation 1
3x + 0=3
3x=3
divide both sides by 3
x=1
substitute for x=1 in equation 2
x+y=5
1+y=5
y=5-1(collecting like terms)
y=4
Because they usually are at the center of data.
Step-by-step explanation:
the "x-2" makes it shift by 2 to the right (functional values are created at x that "should have happened" at 2 x units before, so the whole graph moves to the right).
the 0.4 factor compresses it by the factor 0.4
the "-" at the beginning just "flips" (reflects) it to the other side of the x-axis.
Answer: The correct option is
(B) 
Step-by-step explanation: We are given to select the rational number that is also an integer :
We have
not an integer.
an integer.
0.24 and 2.4 are not integers, they are just rational numbers.
Thus, the required rational number that is also an integer is
Option (B) is CORRECT.
