-25 ≤ -5n ≤ 30
Let's solve one side of the inequality at a time.
-5n ≤ 30
Divide both sides by -5. When you divide by a negative number, it switches the sign.
n ≥ -6
Now, let's do the other side of the inequality.
-5n ≥ -25
Divide both sides by -5.
n ≤ 5
Our new compound inequality looks like: -6 ≤ n ≤ 5
Put one point at -6 and one point at 5 and connect the dots to graph the inequality.
So, first you need to put both of them in Point slope. They are, y - 1= 1(x-6) and y - 3 = -3 (x-2). Make them both slope intercept. Which is, y=x-7 and y=-3x-3. Then, g=find the point of interception. Which is, (1,-6)
2 (t+5) > 4t-7 (t+3)
distribute
2t+10> 4t -7t-21
2t+10> -3t-21
add 3t to each side
5t+10>-21
subtract 10 from each side
5t>-31
divide by 5
t>-31/5
t> -6 1/5
Answer: t> -6 1/5
I believe the answer to your question is C
Answer:
8 = x
Step-by-step explanation:
all three sides are equal, so it is an equilateral triangle
if it is an equilateral triangle, each angle is 180/3 = 60 degrees
therefore
60 = 7x+4
subtract 4 from each side
60-4 = 7x+4-4
56 = 7x
divide by 7 on each side
56/7 = 7x/7
8 = x
