Answer:
y = 2x+5
Step-by-step explanation:
rearrange the equation to make y the sof
y = 1/2x - 3
to find gradient of perpendicular line
1/2 ÷ ( - 1 )
y = -2x + c , the replace the coordinates (-3,-1)
y = 2x + 5
Answer:
Rule: If working with an inequality and you either mult. or div. by a negative number, you must reverse the direction of the inequality symbol.
Step-by-step explanation:
Your job here is to simplify 9t-4>32, in which the variable (t) is already positive. Here you do NOT switch signs or reverse the direction of the inequality symbol. Adding 4 to both sides, we get 9t > 36, or t > 4.
If, however, you had -9t-4>32 to work with, the situation would be different because t in this inequality is negative. Adding 4 to both sides results in:
-9t > 36. To solve for t, we must divide both sides by -9 AND reverse the direction of the inequality symbol:
t < -4.
Rule: If working with an inequality and you either mult. or div. by a negative number, you must reverse the direction of the inequality symbol.
4-9= -5 that is the answer
