The cost for a 3-hour installation is $195.
A relation between a collection of inputs and outputs is known as a function. A relationship between inputs and outputs in which each input is connected to only one output is called a function. Each function has a codomain, range, and domain.
The hourly charge to install two new programs and a connection is $50.
The computer store charge $45 for the materials.
The function for the cost of the number of hours it takes to complete the job is given as:
C(h) = 45 + 50h
Therefore, the cost for a 3-hour installation is:
C(3) = 45 + 50 × 3
C(3) = 45 + 150
C(3) = $195
The 3-hour installation cost is $195.

Use the Quadratic Formula to solve the equation x2 - 2x = - 9
The required solution of the given quadratic equation is [tex]{\displaystyle x={\frac {2\ - {\sqrt {(-32)}}}{2}}[/tex] and [tex]{\displaystyle x={\frac {2\ + {\sqrt {(-32)}}}{2}}[/tex]
What is Quadratic Formula?In elementary algebra, the quadratic formula is a formula that provides the solution(s) to a quadratic equation.
Given a general quadratic equation of the form
ax^2 + bx + c = 0
with x representing an unknown, with a, b and c representing constants, and with a ≠ 0, the quadratic formula is:
[tex]{\displaystyle x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}[/tex]
and,
Now the given quadratic equation is,
x^2 - 2x = - 9
or, x^2 - 2x + 9 = 0
here, a = 1
b = -2
c = 9
Thus quadratic formula is given as,
[tex]{\displaystyle x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}[/tex]
[tex]{\displaystyle x={\frac {-(-2)\pm {\sqrt {(-2)^{2}-4*1*9}}}{2*1}}[/tex]
[tex]{\displaystyle x={\frac {2\pm {\sqrt {4-36}}}{2}}[/tex]
[tex]{\displaystyle x={\frac {2\pm {\sqrt {(-32)}}}{2}}[/tex]
Thus,we get,
[tex]{\displaystyle x={\frac {2\ - {\sqrt {(-32)}}}{2}}[/tex]
[tex]{\displaystyle x={\frac {2\ + {\sqrt {(-32)}}}{2}}[/tex]
Thus,the required solution of the given quadratic equation is [tex]{\displaystyle x={\frac {2\ - {\sqrt {(-32)}}}{2}}[/tex] and [tex]{\displaystyle x={\frac {2\ + {\sqrt {(-32)}}}{2}}[/tex]

Where will the hour hand of clock stops if it starts from 7 and goes through 3right angles
The hour hand that goes through 3 right angles and starts from 7 will stop at 4.
We can assume that the numbers in a clock are positioned in a circle. The angle in a circle is 360⁰, while the numbers in a clock is 12.
Hence, from each clock number to its consecutive number, the hour hand must travel 30⁰ as shown in the attached picture.
A right angle is equal to 90⁰. This is equal to 3 ⨉ 30⁰. In other words, to travel 90⁰ means to travel 3 hours.
3 right angles = 3 ⨉ 90⁰
= 3 ⨉ 3 hours
= 9 hours.
Thus, the hour hand will go to:
7 + 9 = 16
16 is equal to number 4 in a clock number.
Conclusion: If the hour hand start from 7, it will stop at clock number 4.

X=
Answer:
3/ax-4=20
first add 4 to both sides
3/ax=20+4
multiply by a/3
24a/3
so x=8a
Answer: 1/8a
Step-by-step explanation: add 4 to both sides first, which will give you 3/ax = 24. Now multiply both sides by ax/3 to get rid of the 3/ax, which will then give you 1 = 24 * ax/3, which equals to 1 = 24ax/3. This can be simplified further and you'll get 1 = 8ax. now divide both sides by 8a to isolate x, you will end up with 1/8a = x.

What is the solution set to the equation 2/7-m=4/m - 5-m/7-m
The equation given as 2/(7 - m) = 4/(m - 5) - m/(7 -m) has no real solution for m
How to determine the solution set to the equation?The equation is given as
2/(7 - m) = 4/(m - 5) - m/(7 -m)
Take the like terms of the above equation
So, we have
m/(7 -m) + 2/(7 - m) = 4/(m - 5)
Evaluate the like terms in the above equation
So, we have
(m + 2)/(7 -m) = 4/(m - 5)
Cross multiply the above equation
So, we have
m^2 + 2m - 5m - 10 = 28 - 4m
Evaluate the like terms
m^2 + m + 18 = 0
Using a graphing tool, we have no solution for m
Hence, the equation given as 2/(7 - m) = 4/(m - 5) - m/(7 -m) has no real solution for m

The pool that Reggie drew will be 24 millimeters long, compare to real life which is 24 meters long.
As we can't create a real-life dimension in a small sheet of paper, we opted for a small scale that covers up the large length. As we are given, the scale of the drawing is 4 millimeters: 3 meters, which means 1 millimeter is equal to 3/4 meters, and the size of the pool in real life is 24 meters.
So, the length of the pool in the drawing is = 24*(3/4)

Answer:125.666
Step-by-step explanation:
Meena drove 245 miles in 5 hours. if she continued at the same rate, how long would it take to travel 196 miles
Meena would take 4 hours to drive 196 miles.
We will begin with calculation of number of miles Meena drives in 1 hour. We need to perform division as per the formula given below to find the speed. Then we will calculate the time required for driving 196 miles.
So, formula stating rate or speed of driving -
Speed = distance ÷ time
Keep the values in formula to find the speed
Speed = 245 ÷ 5
Performing division
Speed = 49 miles per hour
So, Meena drives 49 miles in 1 hour.
For driving 196 miles, the time required = (1 ÷ 49) × 196
Performing multiplication and division
Time required = 4 hours
Hence, Meena will require 4 hours to drive 196 miles.

What is inequality form ?
The notation a ≠ b means that a is not equal to b; this inequation sometimes is considered a form of strict inequality. It does not say that one is greater than the other; it does not even require a and b to be member of an ordered set.
What is interval notation?
Interval notation is a way to describe continuous sets of real numbers by the numbers that bound them. Intervals, when written, look somewhat like ordered pairs. However, they are not meant to denote a specific point. Rather, they are meant to be a shorthand way to write an inequality or system of inequalities.

What is a bank?An example of a financial institution that lends money is a bank, which both collects deposits from the public and creates demand deposits. Through the capital markets, the bank may engage in lending activities directly or indirectly.
Banks are heavily regulated in most countries because they are essential to the financial stability and economic health of a nation. The fractional reserve banking system, in which banks maintain liquid assets that are only partially comparable to their current liabilities, has been institutionalized in the majority of countries. In addition to other constraints intended to assure liquidity, banks are often subject to minimum capital requirements based on an international set of capital norms known as the Basel Accords.
