Answer:
y=0.5x-7
Step-by-step explanation:
x-2y=8
2y=x-8
y=0.5x-4 m1=0.5
m1=m2=0.5 - the slope for parallel lines are equaly
y=m2x+b
-6=0.5*2+b
b=-7
y=0.5x-7
Answer:
0.368
Step-by-step explanation:
Number of red marbles= 3
Number of blue marbles= 4
Number of green marbles= 7
Total number of marbles= 3+4+7= 14
Let the first ball is taken out to be red
P(R)=
than again a second ball is drawn, number of balls left= 14-1=13
Number of red= 2
P(R)=
Total probability=+
Total probability= 0.368
Hence, the correct answer is 0.368
The second one seems about right.
1. <span>The name of period that has 486 in the given number which is 751 486 is hundreds.
period is considered to a group of places of the digits, like the given number 486 is the group of hundred because the highest number it contains is 400.
=> 400 + 80 + 6
=> 4 hundreds + 8 tens + 6 ones
=> 486
while 751 is the period of hundred thousands.
=> 700 000 + 50 000 + 1 000
=> 751 000
