Answer:
<h2>f(2) = - 12</h2>
Step-by-step explanation:
f(x) = x - 14
To find f(2) substitute the value of x that's 2 into f(x). That is for every x in f(x) replace it with 2
We have
f(2) = 2 - 14
We have the final answer as
<h3>f(2) = - 12</h3>

Step-by-step explanation:
Answer:
W=30m L=90m
Step-by-step explanation:
A =2,700 m²
L=W+60
we know that area of a rectangle is A=L*W so we sustitute what we know
A=L*W
2,700 = (W+60)*W distribute
2,700 = W² +60W subtract 2,700 from both sides
W²+60W-2,700 =0
solve the quadratic equation with quadratic formula or on the calculator on the graph and will get W= -90 and W=30. Reject the -90 value because we can not have negative measurements. Our solution is W=30
L=A/W=2,700/30=90
Answer: No. both are independent quantity. Therefore, the number of books purchased does not affect the value of m.
Step-by-step explanation:
Given: Julio and his sister bought 8 books and m magazines for $1 each.
The amount of money that Julio spent is represented by the expression 1/2(m+8)
Thus, the amount she and her sister will pay is dependent on the number of books and the number of magazines, but the number of magazines and the number books are independent quantity.
Therefore, the number of books purchased does not affect the value of m.
