-8≥-5x+2>-38
-10≥-5x>-40
2≤x<8 (when divided by a negative number, the sign changes from ≥ or > to ≤ or <)
so x is between 2 (include 2, a solid dot) and 8 (doesn't include 8, a hollow bubble)
the third choice is correct.
Answer:
Linear
Step-by-step explanation:
y=4x+2. eq1
y=5x. eq2
4x=2-y
x=(2-y) /4
substitute in equation 2
y=5(2-y) /2
y=(10-5y)/2
4y=10-5y
9y=10
y=10/9
substitute in equation 2 or 1
substituting in equation 2
10/9=5x
x=10/45
x=10/45 y=10/9
you can verify it also.
