Answer:
(g · f)(4) = 45
Step-by-step explanation:
f(x)=4x+1
g(x)=x² - 4x- 5
(g · f)(x) = 4(x² - 5) + 1
(g · f)(4) = 4(4² - 5) + 1
Following pemdas
(g · f)(4) = 4(16 - 5) + 1
(g · f)(4) = 4(11) + 1
(g · f)(4) = 44 + 1
(g · f)(4) = 45
So p - $15 = $49 and to solve it subtract 15 from 49 and then you will get your answer
Answer:
Is this the whole question?
Step-by-step explanation:
<span><span>1.
</span>Jill’s fish weighs 8 times as much as her
parakeet.
Together they weigh 63 ounce.
Find the weight of the fish.
=> Jill’s Fish = 8x
=> Parakeet = x
Equation:
=> 8x + x = 63
=> 9x = 63
=> 9x / 9 = 63 / 9
=> 7 ounce
Thus the weight of fish = 8(7)
=> 56 ounce
Which is 8 times as much as parakeet which is 7
=> 56 + 7 = 63 ounce</span>
The correct answer is A. A whole number
Explanation:
In mathematics, whole numbers include numbers that do not include a fraction, for example, the number 4.2 includes a fraction, and therefore it is not a whole number. Moreover, whole numbers include numbers from 0 to infinity but not negative numbers. This means the number -5 is not a whole number because even then this does not include a fraction it is a negative number. According to this, this number is an integer (it does not include fractions), a rational number (it can be expressed as a fraction), and a real number (it can be represented in a line), but not a whole number.
