have a good day :)
Step-by-step explanation:
Subtract 3t from the equation to get 2t=-7. Multiply by three to find that 6t=-21.
Answer:
Step-by-step explanation:
Formula is y= mx+b
b= slope intercept which is 3
m is the slope and it is 3/2 = 1.5
so...
y= __x+__
y= 1.5x+ 3

Answer:
Number of Model A press = 9 and Number of Model B press = 5
Step-by-step explanation:
Number of books Model A can print per day = 70
Number of books Model B can print per day = 55
Let x be the number of Model A press and y be that of Model B press.
Total number of printing presses = 14
x + y = 14 ----------------1
Total number of books printed per day = 905
70x + 55y = 905-------2
Putting y = 14 - x in equation 2, we get:
70x + 55(14 - x) = 905
15x = 135
x = 9
y = 14 - 9 = 5
Hence number of Model A press is 9 and that of Model B press is 5.
Proof method:
1. Calculate the length of each side, DE,DF,EF
2. Compare the length of them, if any pair of them is equal, then it's isosceles.
