Answer:
option D
Step-by-step explanation:
m=slope
m=(y2-y1)/(x2-x1)
m=(10-4)/(6-2)
m=6/4
m=3/2
Prob of picking 9 in 1st turn = 4 / 52
Prob of picking 9 is 2nd turn = 3/51
So Probability for both = 4 * 3 / (52*51)
=1/221
<span> (-2.9a + 6.8 ) + (4.4a - 7.37)
=</span> -2.9a + 6.8 + 4.4a - 7.37
= - 2.9a + 4.4a + 6.8 - 7.37
= 1.5a -0.57
Answer: 1.5a - 0.57
This is incorrect. X can be negative, making the expression on the left less than 0. If x were -10, then:
3 x -10 + 1 > 0
-30 + 1 > 0
-29 > 0
Is NOT true.
Expression: 5.75 + <span>2.50x
hope that helps
