Answer:
g(-4) = 24 + 3 = 27
Step-by-step explanation:
We find the value of g(-4) by substituting -4 for x in g(x)= −6x + 3:
g(-4) = -6(-4) + 3, or
g(-4) = 24 + 3 = 27
Answer:
(2r - 8)(2r + 8).
Step-by-step explanation:
4r2 – 64
This is the difference of 2 squares so we take the square root of 4r2 and 64 and write:
= (2r - 8)(2r + 8).
Answer:
m ≤ 250
(where m is miles)
Step-by-step explanation:
He can go a maximum of 250 miles on a tank of gas (25 miles per gallon * 10 gallons), and this can be expressed as follows:
m ≤ 250
1st he should have found the GCF of 60
2nd he should have found the GCF of 90,
the GCF of 30 = 2x3x5
the GCF of 90 = 2x3²x5
So the GCF of 60 and 90 is 2x3x5 = 30
P(winning) = 4/52 = 1/13
P(losing) = 48/52 = 12/13
Expected value
= 1/13 ($498) + 12/13 (−$2)
= $498/13 − $24/13
= $474/13
= $36.46
