We are given the expression:
U = E * P
The equality symbol “ = “ means that for all cases, the
value of U and E * P must always be equal. This means that whatever happens on
the left side, must equally happen on the right side.
So what this actually means is that, if we double U so we
must also double the expression E * P, that is:
2 U = 2 (E * P)
However since P stays constant in the process, therefore
only E is changed, hence:
2 U = P * 2 E
So we can see that E is also doubled.
What I like to do with negative numbers is count back from the positive to the negative here I can make a number line! :) think of it this way 0 is the middle of your positive and negative numbers it’s where they are coming together!
-5 -4 -3 -2 -1 0 1 2 3 4 5
————————————
Here #5 (on your paper)
8-11 so count back from 8 eleven times
8-11= -3
If u need anymore help I’m here :)
Ik negative & positive numbers are pretty tricky lol
Best of luck :))
Answer:
Step-by-step explanation:
Y = Ax2 Bx C
Enter coefficients here >>> 4 7 -20
Standard Form: y = 4x²+7x-20
1.75 0.875 0.765625 3.0625 -23.0625
Grouped Form: No valid Grouping
Graphing Form: y = 4(x+0.88)²-23.06
Factored Form: PRIME
Solution/X-Intercepts: -3.28 AND 1.53
Discriminate =369 is positive, two real solutions
VERTEX: (-0.88,-23.06) Directrix: Y=-23.13
The lines intersect at (1, -1)
hope it helps!!
