Answer:
B
Step-by-step explanation:
-3 < 2x + 3 <= 5
-6 < 2x <= 2
-3 < x <= 1
such a condition is an "and" condition. both parts need to be fulfilled.
-3 < x and x <= 1
if you are still not seeing it :
-3 < x is the same as x > -3
now you see that B is the right answer.
x > -3 and x <= 1

Step-by-step explanation:
Answer:
x+5y+5=0
Step-by-step explanation:
y=5x+6
Therefore the gradient of the line = 5
Now reciprocate the gradient and negate it
i.e -1/5
let (x,y) and (-15,2) be points on the line
y-2/x-(-15)=-⅕
5y-10=-x-15
5y-10+15+x=0
x+5y+5=0
Therefore the equation of the line =
x+5y+5=0
