1)
15 > -2x-9
15+9 > -2x
24÷(-2) < x (the sign flips because you divide both sides by a negative number)
Hence, x > -12
2)
3x + 8 < 29
3x < 29-8
3x < 21
x < 7 (tada the answer)
Answer:
C. In 2001, the temperature was 83°F.
Step-by-step explanation:
79 is 4 less than 83.
The temperature in 2001 was 83 °F.
Answer:
125
Step-by-step explanation:
1,000/8 because all the outcomes are evenly likely
The diameter of a circle by definition goes from one "side" of the circle to the other "side" and goes through the center. If we are given the coordinates of the endpoints of the diameter, we need to find the midpoint of that segment to find the center of the circle. The midpoint formula is as follows

. Filling in accordingly, we have

. Doing the math on that gives us a midpoint of (-7, -6), which is also the center of the circle.
Let's make the equation.
2(N+9)=6
Let's divide both sides by 2.
n+9=3
Now subtract 9 from both sides.
n=-6
So, the number is -6.
