Answer:
a) slope intercept form: y = -5/14 x + 7/2
b) point slope form: y - 1 = 3/2(x - 4)
Step-by-step explanation:
a) Line A: (4,1) and (0, 7/2)
Slope = (1 - 7/2)/(4 - 0)
Slope = - 5/2 * 1/4
Slope = - 5/14
Equation in slope intercept form:
y = -5/14 x + 7/2
b)
(4,1) and (0, -5)
Slope = (1 + 5)/(4 - 0) = 6/4 = 3/2
Equation in point slope form:
y - 1 = 3/2(x - 4)
Answer: Probability is 0.00205 = 0.205%
Step-by-step explanation: P(rain) = 0.71, P(no rain) = 0.29.
P(no rain in 5 days)= 0.29·0.29·0.29·0.29·0.29= 0.00205
2x-1=5
2(3)-1=5
6-1=5
5=5
x=3
B) -23 because a double negative is a positive so it’s -35 + 12 which is -23
