Answer:
Below in bold.
Step-by-step explanation:
4x + y = 9
Let's put x = 0 then:
4(0) + y = 9
0 + y = 9
y = 9
So one. ordered pair that is a solution is (0, 9)
4x=2y+6
(-2y=-4x+6)/-2
y=2x-3
y-int: (0, -3)
Step-by-step explanation:
b.square root
x²-1=15
x²=16
square root on both side
x±4
A=9
b=7
c>a-b
c>2
c<a+b
c<7+9
c<16
⇒c∈(2,16)
⇒ The correct answer is A,B,C,E
