Answer:
y=-8
Step-by-step explanation:
Remember PEMDAS (Parentheses/Exponents/Multiplication/Division/Adding/Subtracting)
Multiply 4 and -2= -8
-8-2y=8
Now do inverse operations
to get rid of the -8 you add it to the other side = -2y=16
Then to get rid of the -2 you divide it out to get the y by it self to get y=-8
Answer: The point (5,-20) only satisfies the second inequality statement in the system of inequalities shown.
Step-by-step explanation:
It isn't super clear exactly what you're asking, but the first thing we can do is see if the point (5, -20) satisfies the system of equations.
So, we start by plugging in -20 for y and 5 for x.
y > -2x-3
-20 > (-2)(5) - 3
-20 > -10-3
-20 > -13. - we can see that the coordinates DO NOT satisfy the first inequality, now we can try the second equation.
y ≤ 3x + 2
-20 ≤ 3(5) + 2
-20 ≤ 15 +2
-20 ≤ 17 - this inequality is true because -20 is indeed less than 17.
