using only the information derived in question 2, 3, and 4, which theorem
D. AAS
Answer:
x=-5/2, -3
Step-by-step explanation:
2x^2+11x+15=0
factor out the trinomial
(2x+5)(x+3)=0
zero property,
2x+5=0, x+3=0
2x=0-5=-5, x=-5/2
x=0-3=-3
Answer:
f(x) = x(x - 4)(x + 3)
Step-by-step explanation:
given f(x) with zeros x = a and x = b then the corresponding factors are
(x - a) and (x - b)
f(x) is then the product of these factors
Given zeros are x = 4, x = 0, x = - 3 then the factors are
(x - 4) , (x - 0), (x - (- 3)) , that is
(x - 4) , x , (x + 3)
f(x) = x(x - 4)(x + 3)
Answer:
B) 2.4 inches
Step-by-step explanation:
The total amount of rain is 28.8 inches over 12 months. To find how much rain falls averagely in <em>one </em>month you need to divide the total by the amount of months. 28.8/12 = 2.4
Let n represent the amount Colin earned on Sunday.
On Sat. he earned n/2; on Sun. he earned n; and on Friday he earned (1/2)(n/2).
Then n/2 + n + n/4 = $70
Mult. all terms by 4 to eliminate fractions:
2n + 4n + n = $280
7n = $280 => n = $40
Colin earned n/2, or $20, on Saturday; n, or $40, on Sunday; and n/4, or $10, on Friday.
Note that $20 and $40 and $10 add up to $70, as they must.
