Answer:
Refer the attached figure.
Step-by-step explanation:
Given : System of equation 
To find : Which graph represents the solution to the given system?
Solution :
Equation
plotted with a red line passing through (-1,0) and(0,4).
Equation
plotted with a blue line passing through (0,-3) and(0.75,0).
As their slopes are equal i.e. m=4.
So, the equation of lines are parallel.
There is no solution of the equations.
Refer the attached figure of the equations.
Answer:
1, 4, & 6
Step-by-step explanation:
1. is a fraction and fractions are rational numbers
2. 11 is not a perfect square so the answer should be a terminating decimal and terminating decimals are irrational numbers
3. is a terminating decimal and an irrational number
4. .23 is a decimal which is a rational number since it can be made into the fraction 23/100
5. is a terminating decimal which is an irrational number
6. is a fraction which is a rational number

Answer:
x = -2, y =-2
Step-by-step explanation:
5x - 6y = 2
-5x - 5y = 20
Add the two equations together to eliminate x
5x - 6y = 2
-5x - 5y = 20
------------------------
-11y = 22
Divide by -11
-11y/-11 = 22/-11
y = -2
Now we can find x
5x -6(-2) =2
5x +12 = 2
Subtract 12 from each side
5x +12-12 =2-12
5x = -10
Divide by 5
5x/5 = -10/5
x = -2
