Find two numbers that multiply to -30 (last term) and add to 7 (middle coefficient)
The two numbers are 10 and -3
10 times -3 = -30
10 plus -3 = 7
Using those two values gets us the two factors (y+10) and (y-3)
Therefore, y^2+7y-30 factors to (y+10)(y-3)
The equation y^2+7y-30 = (y+10)(y-3) is true for all values of y.
Answer:
24 mph (miles per hours)
Step-by-step explanation:
she is going 2 miles every 5 minuets. 5 can go in to 60 12 times. and 2 times 12 is 24.
Answer:
0.0019390
Step-by-step explanation:
10% of people do not like the taste of cilantro
A researcher takes a random sample of 15 people and surveys whether they like cilantro
Use the binomial distribution to compute the probability that exactly 6 of the people in the sample do not like cilantro.
Probability of success = 0.10 = p
Probability of failure = 0.9 =q
n = 15
r = 6
Formula : 
Hence the probability that exactly 6 of the people in the sample do not like cilantro is 0.0019390
Step-by-step explanation:
step 1. The correct question is "solve the system of equations."
step 2. when you graph these equations they are parallel since they have the same slope.
step 3. There is no solution to the system when the lines are parallel ( they dont cross).
Answer:
the slope is -1 2/3
The y-intercept is -1.4
The equation in y = mx + b form is
y = –5/3x - 2 1/3
