Answer: B
Step-by-step explanation:
the reason the answer is B is because you want to:
1st. count how many down or up on the the Y line. In this case its 2 down which is -2.
2nd. count the boxes over. It's 2 boxes over so that gives u your top number.
3rd and final step. you count up till you reach the top point. that 5 space and so 5 is your bottom number.
Here's a trick that I use. I draw a triangle. Once u plot the points you connect them with a line is the line is going left its a negative of its going right its a positive.
then while you count the blocks draw a line in the end it turns into a triangle.
Here's a example.
PS. the top number of the fraction and the last number always match. Thats another way you can tell if its a negative or a positive.
Answer:
Step-by-step explanation:
Hello!
Be X: air pressures of properly inflated sports balls.
<em>Average recommended psi Tolerance(pounds per square inch)</em>
<em>Soccer ball 12.05 ±3.55</em>
<em>Basketball 8.00 ±0.5 </em>
<em>Volleyball 4.44 ±0.18</em>
Each recommendation is expressed like the "average air pressure" ± "standard deviation of the recommended air pressure" so if you express it in inequality it will be:
X[bar]-S ≤ X ≤ X[bar]+S
So for each ball type, you can write it as:
<u>Soccer ball</u>
12.05-3.55 ≤ X ≤ 12.05+3.55
8.5 ≤ X ≤ 15.6
<u>Basketball</u>
8.00-0.5 ≤ X ≤ 8.00+0.5
7.5 ≤ X ≤ 8.5
<u>Volleyball</u>
4.44-0.18 ≤ X ≤ 4.44+0.18
4.26 ≤ X ≤ 4.62
I hope this helps!

Answer:
D. 25
Step-by-step explanation:
in triangle congruence statements the order of the letters tells you which pieces of the triangles line up, thus ab = de, bc = ef, and ac = df, since ac = 25 that means df = 25
