hey! the correct answer is 0.81
hope it helps :)
Answer:
1418700
Step-by-step explanation:
type it into the calculator and bam
4(x+3)+x=0
4x+12+x=0
5x+12=0
5x=-12
x=-2.4
the first number -2.4
the second number 1.4
the third number 5.6
Step-by-step explanation:
second one because
only x+2y=8 passes through the point (2,3)
the proof is 2+2*3=2+6=8
if we replace the given point to the other equations we will take wrong results for example
first equation
x+2y=4. 2+2*3=2+6=8 that is not equal to 4
