Step-by-step explanation:
a
You have to do substitution in both sides e) (-4,2)
Answer:
(x-9)(x-3)
Step-by-step explanation:
Look to the number on the right, 27, and list out the factors. (1 and 27, 3 and 9, -1 and -27, -3 and -9)
Next, find the factors that would equal the middle number, -12, when added. -3 and -9 add to -12. Therefore, choose these numbers and put them in the form (x-9)(x-3).
Answer:
Solutions given:
Velocity ratio V.R =5
effort =500N
efficiency =80%
magnitude of load=?
mechanical advantage [M.A ]
we have
efficiency =M.A/V.R*100%
80=M.A./5*100
80/100*5=M.A
M.A.=4
again
we have
M.A =load/effort
4=load/500
load=500*4
load=2000N
<h3>
<u>the magnitude of the load is 2000N</u>.</h3>
Answer:the football team played 25 games in all
Step-by-step explanation:
Let x represent the total number of matches that the football team played.
The football team won 10 matches out of the total number of matches they played. if their win percentage was 40, it means that
10/x × 100 = 40
1000 = 40x
x = 1000/40 = 25
