We are to select 2 people to sit in first row from 6.
This is a problem of Combinations. We are find permutation of 6 people taken 2 at a time. This can be represented as 6C2.
So, the answer is option B
Answer:
Put this table into Desmos and then wherever the line crosses the y-axis, is your y-intercept.
Answer:
4700
Step-by-step explanation:
Rounding to 100: Look at the tenth value. If this value is greater than or equal to 5, round up. If this value is less than 5, round down.
9635 = 9600
4891 = 4900
9600 - 4900 = 4700
You can check if it's accurate by comparing it to the original.
9635 - 4700 = 4744
Answer:
12x8x10=960
Step-by-step explanation:
24.) y = mx + b
slope(m) = 0.25
(0,4)...x = 0 and y = 4
now we sub and find b, the y int
4 = 0.25(0) + b
4 = b
so ur equation is : y = 0.25x + 4
26.) y = mx + b
slope(m) = 3/2
(-5,1)....x = -5 and y = 1
sub and find b, the y int
1 = 3/2(-5) + b
1 = - 15/2 + b
1 + 15/2 = b
2/2 + 15/2 = b
17/2 = b
ur equation is : y = 3/2x + 17/2
28.) y = mx + b
slope(m) = 4
(0,0)...x = 0 and y = 0
time to sub
0 - 4(0) + b
0 = b
so ur equation is : y = 4x + 0.....or just y = 4x
30.) (7,1)(7,8)....notice how the x's are the exact same number....this
means that ur line is a vertical line with a slope that is undefined.
ur equation is : x = 7
32.) (-2,-3)(0,0)
slope = (0 - (-3) / (0 - (-2) = (0 + 3) /(0 + 2) = 3/2
y = mx + b
slope(m) = 3/2
(0,0)...x = 0 and y = 0
sub
0 = 3/2(0) + b
0 = b
ur equation is : y = 3/2x + 0 or just y = 3/2x
34.) (1/3,0)(0,-1/4)
slope = (-1/4 - 0) / (0 - 1/3) = (-1/4)/(-1/3) = -1/4 * -3 = 3/4
y = mx + b
slope(m) = 3/4
(0,-1/4)...x = 0 and y = -1/4
sub
-1/4 = 3/4(0) + b
-1/4 = b
so ur equation is : y = 3/4x - 1/4
