Option 1 is the correct answer. The open circle means that the end value (78) is not included in the solution. That is why the inequality statement says 78 > x.
Answer:c
Step-by-step explanation: i think hope this helps
Answer: X less than of equal to 11/2
Explanation:
Answer:
Perpendicular means that,second gradient equals to first one as:
So,conducting the second equation to the form y=mx+c: 3y= -2x-5
So it's gradient is
converting to
equals to 1.5 or at least
Y find the equation of the first line you've got to use the formula: y-y1=m (x-x1)
y-1=1.5 (x+6)
y-1=1.5x+9
<u>y</u><u>=</u><u>1</u><u>.</u><u>5x</u><u>+</u><u>10</u><u> </u>is the equation of the first line.
