The factorization of A is y = (x - 8)(x + 7).
The factorization of B is y = (x + 1)(x - 4)(x - 5)

In order to find these, you must first find where each graph crosses the x-axis. In the first problem it does so at 8 and -7. In order to find the correct parenthesis for those, you need to write it out as a statement and then solve for 0.

x = 8 ---> subtract 8 from both sides
x - 8 = 0
This means we use (x - 8) in our factorization.

You then need to repeat the process until you have all the pieces. In the second problem, there will be 3 instead of 2 since it crosses the axis 3 times.

Answer:

£102.04

Step-by-step explanation:

£1250 - £1100 = £150

printer sold for £150

£150 = 147%

1% = 1.0204

100% = 102.0408

A parachute speed during a free fall reaches117 miles per hour What is the speed in feet per second At the speed how many feet w

qwelly [4]

Answer:

Speed is 171.6 ft/s and distance is 1716 feet

Step-by-step explanation:

Given that,

The speed of a parachute = 117 miles per hour.

1 mph = 1.47 ft/s

117 mph = 171.6 ft/s

We need to find the distance it travel during 10 s. We know that the distance covered is equal to the product of speed and time taken. So,

d = vt

$d=171.6\ ft/s\times 10\ s\\\\=1716\ \text{feet}$

Hence, this is the required solution.

a buret is a tool designed to transfer precise amounts of liquid .A buret initially contains 70.00 millimeters of a solution and

katrin [286]

Let:

Vbu= Volume of the buret

Vbk= Volume of the beaker

A buret initially contains 70.00 millimeters of a solution and a beaker initially contains 20.00 ml of the solution the buret drips solution into the Beaker. each drip contains 0.05 mL of solution, therefore:

x = Number of drips

a = volume of each drip

$\begin{gathered} Vbu=70-ax \\ Vbk=20+ax \\ \text{where:} \\ a=0.05 \\ Vbu=70-0.05x \\ Vbk=20+0.05x \end{gathered}$

after how many drips will the volume of the solution in the buret and beaker be equal ? Vbu = Vbk:

$\begin{gathered} Vbu=Vbk \\ 70-0.05x=20+0.05x \\ \text{Solve for x:} \\ 0.1x=70-20 \\ 0.1x=50 \\ x=\frac{50}{0.1} \\ x=500 \end{gathered}$

Abril earned a total of $60 mowing lawns around her neighborhood. she charges $8 an hour and received $20 in tips .use the equat

zmey [24]

Answer:

She spent 5 hours mowing lawns.

Step-by-step explanation:

To solve, we will just use some algebra

8h + 20 = 60 | Subtract 20 from both sides

8h = 40 | Divide both sides by 8

h = 5

We can confirm this by plugging it back into the original formula.

8(5) + 20 = 60

40 + 20 = 60

60 = 60
