Find the inverse of the function: f(x)=1/5x+4
A f−1(x)=x−4
B f−1(x)=5x−20
C f−1(x)=−5x−4
D f−1(x)=4x−5
Answer:
B. [tex] {f}^{ - 1} (x) = 5x - 20[/tex]
Step-by-step explanation:
[tex]f(x) = \frac{1}{5} x + 4[/tex]
[tex]y = \frac{1}{5} x + 4[/tex]
[tex]x = \frac{1}{5} y + 4[/tex]
[tex] \frac{1}{5} y + 4 = x[/tex]
[tex]y + 20 = 5x[/tex]
[tex]y = 5x - 20[/tex]
[tex] \boxed{\green{{f}^{ - 1} (x) = 5x - 20}}[/tex]

Jenna bought a gallon of milk at the store for $3.58. About how much change did she receive from a $20 bill?
Hi! I'm happy to help!
When Jenna bought the milk, it deducted (subtracted) $3.58 from her $20. So, let's subtract that here:
20.00
- 3.58
We have to borrow:
19.9(10)
- 3.58
10-8=2
19.9(10)
- 3.58
. 2
9-5=4
19.9(10)
- 3.58
.42
9-3=6
19.9(10)
- 3.58
6.42
and 1-0=1
19.9(10)
- 3.58
$16.42
So, Jenna would receive $16.42 in change for her $20 bill.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The correct option is B.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
From the given equation that is true are,
A. 63 x 103 = 63,000
If we multiply 63 and 103 the product will be 6,489. Since the two sides of the equation are not true, therefore, the given equation is false.
B. 63 x 10,000 = 630,000
If we multiply 63 and 10,000 the product will be 630,000. Since the two sides of the equation are true, therefore, the given equation is true.
C. 63 x 102 = 630
If we multiply 63 and 102 the product will be 6,426. Since the two sides of the equation are not true, therefore, the given equation is false.
D. 63 x 1,000 = 6,300
If we multiply 63 and 1,000 the product will be 63,000. Since the two sides of the equation are not true, therefore, the given equation is false.
E. 63 x 105 = 6,300,000
If we multiply 63 and 105 the product will be 6,615. Since the two sides of the equation are not true, therefore, the given equation is false.
Hence, the correct option is B.

15. The total consumption of fruit juice in a
particular country in 2006 was about
2.28 x 109 gallons. The population of that
country that year was 3 x 108. What was the
average number of gallons consumed per
person in the country in 2006?
Answer:
total amount of fruit juice consumed is 2.28 x 10^9
total population = 3 x 10^8
per person is
total consumption / total population
therefore;
2.28 x 10^9/3 x 10^8
= 7.6 gallons per person
hope it's helpful
The average number of gallons consumed per person in the country was 7.60 gallons per person.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Given that,
Total consumption of fruit juice 2.28 x 10⁹ gallons
The population of that year = 3 x 10⁸
The average number of gallons consumed per person ⇒
2.28 x 10⁹ / 3 x 10⁸
⇒ 22.8 x 10⁸ / 3 x 10⁸
⇒ (22.8/3) × 10⁸/10⁸
⇒ 7.6
Hence "The average number of gallons consumed per person in the country was 7.60 gallons per person".

If it takes a fourth of a cup of oil to make 10 cookies, how much oil would it take to make 50 cookies? ?
Answer:
5/4 or 1 1/4 cup of oil
Step-by-step explanation:
Let's make a ratio. 1/4:10. We need to multiply 10 by 5 to get 50 cookies and do the same on the other side of the ratio. 1/4x5=5/4 or 1 1/4 and 10x5 is 50. So our final ratio would be 5/4:50. Hope this helped.

A circle has a circumference of 18cm. What is the diameter of the circle?
Answer:
Around 5.73. The exact answer is 18/pi. Why? The diameter is twice the radius (2r) The formula of the circumference if 2 pi R
if we divide 18, the circumference by pi, we get the diameter.
Step-by-step explanation:
Answer:
18/π
Step-by-step explanation:
Since 2 × π × r is the circumference of the circle,
2πr = 18
πr = 9
r = 9/π
Since the diameter is 2x the radius,
2r = d
2 × 9/π = d
18/π = d

Answer:
The second and third boxes. m=-10/4 & -5/2 & the last one
Step-by-step explanation:
We know the answer is negative so we need to add a larger number to get the 3/4 to the negatives. 3-10= -7, so -10/4 and -5/2 is equal to -10/4
Answer:
The second one m= -10/4, the third one m= -5/2, and the last one -5/4+m= -15/4
Step-by-step explanation:
You find m by solving -7/4 - 3/4 = m. Thats the second option -10/4.
When you simplify, you get -5/2, the third option.
Finally, -5/4+m= -15/4 is equal to -15/4 -(-5/4)=m. Subract and you get -10/4. That makes the original equation equal to the last option.
