Answer:

2

Step-by-step explanation:

x^2 = 16

x = + √16

x = + 4

therefore

x= -4 or 4

there are 2 solutions in the equation

The formula for the area of a circle is: radius x radius x pi/3.14

Answer:

  126.7 if B=80

  93.3 if B=70

Step-by-step explanation:

Let F represent the student's score on the final exam, and let B represent the percentage required for a grade of B. Then we must have ...

  0.60(61) +0.10(54) +0.30F = B

  B = 0.30F +42

  F = (B -42)/0.3

__

If a grade of B requires 80 points or more, then the required grade on the final is ...

  F = (80 -42)/0.3 = 38/0.3 = 126 2/3

The student must get 126.7% on their final to achieve an overall average of 80.

__

If a grade of B requires 70 points or more, then the required grade on the final is ...

  F = (70 -42)/0.3 = 28/0.3 = 93 1/3

The student must get 93.3% on their final to achieve an overall average of 70.

Answer:

1 and a half cupcakes.

Step-by-step explanation:

6 divided by 4 is 1.5 or 1 1/2.

Answer:

1  1/2

Since, the total number of cupcakes = 6

Hence, If there are 4 people,

And, all of them distribute the cupcake equally,

Then, the cupcake will each person get

= Total number of cupcake/Total number of people

= 6/4

= 1 1/2

Answer: 9y + 7 = y

Explanation:

The phrase, "nine times a number y" is "9y" in the form of an equation. When any term is by a number, they are meant to be multiplied together. So, "9y" means "9 times y".

The phrase, "plus seven" simply means to add seven.

The phrase, "equal to number y" is "= y" because "number y" refers to that term.

And so, all together, you get 9y + 7 = y.

After the transactions amount of money left in account is -$29. Therefore, option B is the correct answer.

A savings account is a bank account at a retail bank. Common features include a limited number of withdrawals, a lack of cheque and linked debit card facilities, limited transfer options and the inability to be overdrawn.

Given that, On this day, you have $10 in your account and go out and use your debit card to buy lunch for $12, a movie ticket for $12 and dinner for $15.

Here, amount drawn using debit card is

12+12+15=$39

Money left in the account = 10-39

= -$29

After the transactions amount of money left in account is -$29. Therefore, option B is the correct answer.

Answer:

Moving to the right by 5 units

Moving up by 1 unit

Step-by-step explanation:

The basic absolute value function is f(x) = |x|

The graph vertex is at the origin.

Adding a value inside the absolute value brackets changes the vertex of the graph horizontally.

Adding a value outside the absolute value brackets changes the vertex vertically.

Here, in the absolute value, we are subtracting by 5, so we move to the right 5

Outside the brackets, we are adding 1, so we move up 1.
