Answer:
Step-by-step explanation:
<h3>Given</h3>
- f(x) =
<h3>To find </h3>
<h3>Solution</h3>
<u>Change f(x) → x, and x → y, and solve for y:</u>
- x =
- x² = 7y - 21
- 7y = x² + 21
- y = 1/7x² + 3
<u>y = f⁻¹(x)</u>
Vx = axis of symmetry
Vx=-b/2a
b=4 and a=1
Vx=-4/2
Vx=-2
therefore, the AOS is x= -2
<em>IMPORTANT THIGNS TO REMEMBER:</em>
- Has 20 lb. dog food!
- Gives dog 1 3/5 everyday!
- Find how much eaten after 2 days!
- Find how much is left!
<em>ANSWER:</em>
Dog has eaten 3 1/5 after 2 days!
There is 16 4/5 left in bag!
<em>EXPLANATION:</em>
Since she gives 1 3/5 to her dog everyday and their asking for 2 days you would multiply 1 3/5 × 2 OR add 1 3/5 + 1 3/5
Which would give you 3 1/5
So, the dog has eaten 3 1/5 lb. of dog food in 2 days.
However then, you would subtract 20 lb. - 3 1/5 lb. because there is 20 lb. dog food in all and the dog has eaten 3 1/5 of it. This would give you 16 4/5 lb.
Meaning there is 16 4/5 lb. left in the bag of dog food!
Answer: A
Step-by-step explanation:
The easiest way to solve this problem would to first figure out how long it takes for Mak to run 1 mile. To do that, you would need to divide 50 by 4 which would give you 12.5. So, it takes Mak 12 and a half minutes to run 1 mile. From there, you would need to multiply 12.5 by 10 to get 125. Finally, you wold need to simplify 125 minutes to hours giving you 2 hours and 5 minutes.
