Answer:
1.898 × 10^27
Step-by-step explanation:
We move the decimal point to the left between 1 and 8
and that is 27 places so you multiply the number you get by 10^27
The area is 443,556. you multiply 999 by 444
Answer:
There is no x value, as there is no solution
Step-by-step explanation:
we have
2x+y=1
Isolate the variable y
y=-2x+1 -----> equation A
4x+2y=-1 ---> equation B
Solve the system of equations by substitution
Substitute the equation A in the equation B and solve for x
4x+2(-2x+1)=-1
4x-4x+2=-1
2=-1 ------> is not true
therefore
The system has no solution
Equation A and equation B are parallel lines with different y-intercepts
Problem 1 should be B, C, and D. I'm not sure about the rest... Sorry I couldn't be more of a help.
