Which function has the least minimum value and what are its coordinates?
Function 1 has the least minimum value and its coordinates are (−1, 4).
Function 1 has the least minimum value and its coordinates are (0, 7).
Function 2 has the least minimum value and its coordinates are (−1, 7).
Function 2 has the least minimum value and its coordinates are (0, 3).

Answers

The right answer for the question that is being asked and shown above is that: "Function 2 has the least minimum value and its coordinates are (0, 3)." the function that has the least minimum value and what are its coordinates is that Function 2 has the least minimum value and its coordinates are (0, 3).

Isabel bought a new jacket for $48 before tax. She paid 6.5% in sales tax. How much was the sales tax?A)$2.68
B)$2.92
C)$3.12
D)$3.08

Answers

Basing on the data provide above, if Isabel bought the jacket for $48.00 and sales tax is equal to 6.5% which is basically 0.065, we can multiply 0.065 * 48.00 which will be equal to $3.12. So going back to the options the answer is C. which is $3.12.

3 over 5 (r-7) =1
Enter your answer as a mixed number in simplest form in the box

Answers

Answer:

r = 8

Step-by-step explanation:

you start by distributing the 5 to r and -7 to get 3 over 5r - 37. You can then multiply both sides by 5r-37 to get 3 = 5r-37. From here you can add 37 to both sides to get 40 = 5r. From there you divide both sides by 5 to get r = 8

Answer:

r= 8

Find 4 consecutive even integers whose sum is 156?

Answers

x+(x+1)+(x+2)+(x+3)=156
4x+6=156
4x=150
x=37.5 (not an integer)
If x=37 you get 37+38+39+40=154 and if x=38 you get 38+39+40+41=158[/tex]

Answer: The integers are 36, 38, 40, and 42

Step-by-step explanation:

156/2=78

Find even integers by dividing that by two. 39.

So the two middle integers are 38 and 40.

You can go from there.
