Answer: option d.

Step-by-step explanation:

We have the function:

y = f(x) = x^2  - 1

The output is 99 when y = 99, and the input is x.

Then we need to solve:

y = 99 = x^2 - 1

for x.

99 = x^2 - 1

99 + 1  =x^2

100 = x^2

√100 = x

10 = x

The correct option is d, input equals 10.

The equation of a line perpendicular to y = 3 and passes through the point (24, -56).
Lera25 [3.4K]

Answer:

x = 24

Step-by-step explanation:

The given line y = 3 is a horizontal line with slope zero (0).

We wish to find the equation of a line that is perpendicular to y = 3.  Such a line would be a vertical one.  Vertical lines do not have slopes defined (due to division by zero).

Thus the general form of the equation of this new line is x = c.

This new line passes through (24, -56).  Thus, x must be 24:  x = 24

You are a member of a darts team and they have won £1750 prize money in a competition. £70 is to be saved for a celebration part
grandymaker [24]
Most of the information's that are required for solving this question is already given in the question. It is important to check them minutely before trying to solve the problem in hand.
Amount of prize money won by the darts team = 1750 pounds
The amount of money that needs to be saved = 70 pounds
Then
Amount of money remaining after savings = (1750 - 70) pounds
                                                                     = 1680 pounds
The number of  team members in the darts team = 14
So
The amount of money
that each members of the darts team gets = 1680/14
                                                                     = 70 pounds
From the above deduction we can easily conclude that each member of the darts teams will get an amount of 70 pounds.
