A because:
B =(-16) & 16
C=16 & 20
D= 16 & -16
Answer:
-28
Step-by-step explanation:
multiply both 9 and 16 by 4 and then subtract the sum of 16 × 4 from 9 × 4.
(8,5)(-12,-9)
slope = (-9 - 5) / (-12 - 8) = -14/-20 = 7/10
y = mx + b
slope(m) = 7/10
use either of ur points.....(8,5)....x = 8 and y = 5
now we sub and find b, the y int
5 = 7/10(8) + b
5 = 56/10 + b
5 - 56/10 = b
50/10 - 56/10 = b
-3/5 = b
so ur equation is : y = 7/10x - 3/5.....now we put it in standard form
y = 7/10x - 3/5...multiply by 10
10y = 7x - 6.....subtract 7x
-7x + 10y = -6....multiply by -1
7x - 10y = 6
So.....7x - 10y = 3.... IS NOT a good model. Because ur points are not a solution to ur equation.
Answer:
The y-intercept is 15 and the slope is 5.5
y=5.5x+15

Answer:
total sample space is 91
no of cookies in dog shape is 30
therefore
p(d)=30/91
