Answer:
D
Step-by-step explanation:
A: The sum of Y and H is +. If the scale is correct, this is not true. Y is further away from 0 than H is. Suppose H = 5 and Y = -7. Then Y + H = 5 + -7 = - 2
B: E and Y area both minus. The minus signs cancel. Therefore the answer will be + B is wrong.
C: H>0 and E<0. A negative times a positive is a negative not a positive. C is wrong
D: A - H Suppose A = 2 and H = 5 . Then A - H = 2 - 5 which is - 3
This is your answer.
The reason is that H is further from the 0 than A is.
Answer:
y = 3
Step-by-step explanation:
Pythag theorem : ( only applies to RIGHT triangles)
Hypotenuse ^2 = leg1 ^2 + leg 2^2
(7y-1)^2 = (5y-3)^2 + (5y+1)^2
49 y^2 - 14y +1 = 25y^2 -30 y + 9 + 25y^2 + 10y + 1
-y^2 + 6y -9 = 0
or y^2 -6y + 9 = 0 solve by factoring or using Quadratic Formula
( y -3)(y-3) = 0 shows y = 3

Answer:
360,360 groups of 5 people.
Step-by-step explanation:
We have been given that there are 15 people in an office with 5 different phone lines. We are asked to find groups of 5 people that can answer these lines, if all the lines begin to ring at once.
We will use fundamental principle of counting to solve our given problem.
There are 15 people to answer 1st line, that will leave us with 14 people to answer 2nd line.
Now, we will have 13 people to answer 3rd line, that will leave us with 12 people to answer 4th line.
There are 11 people to answer 5th call.
So 5 lines can be answered in ways.
Therefore, 360,360 groups of 5 people can answer these lines.
Answer:
the missing side length is
Step-by-step explanation:
we know that the volume of the rectangular prism is equal to
In this problem we have
using a graphing tool find the x-intercepts of the function
see the attached figure
The x-intercepts are
so
therefore
the missing side length is
