Answer:

p(x) = (5x - 1) (x + 4) (x - 2)

Option B: p(x) = (x - 5)(x + 1)(4x + 1)

You have zeroes when each set of parenthesis equals zero.

x - 5 = 0
Add 5
x = 5

x + 1 = 0
Subtract 1
x = -1

4x + 1 = 0
Subtract 1
4x = -1
Divide 4
x = -1/4

Supposed a Visa card had a credit card number of 4162 0012 3456789a where a is the check number what is the check number? A) 0 B
MrMuchimi

Answer:

Option B) 3

Step-by-step explanation:

we have the number

4162 0012 3456 789a

<u><em>Find the value of a (check number)</em></u>

step 1

Multiply every even-position digit (when counted from the right) in the number by two. If the result is a two digit number, then add these digits together to make a single digit

4162 0012 3456 789a

9(2)+7(2)+5(2)+3(2)+1(2)+0(2)+6(2)+4(2)

(18)+(14)+(10)+(6)+(2)+(0)+(12)+(8)

Remember that If the result is a two digit number, then add these digits together to make a single digit

so

(1+8)+(1+4)+(1+0)+(6)+(2)+(0)+(1+2)+(8)

(9)+(5)+(1)+(6)+(2)+(0)+(3)+(8)=34

step 2

add every odd-position digit

4162 00123456 789a

so

8+6+4+2+0+2+1=23

step 3

Adds  the result in step 1 and the result in step 2

34+23=57

The check-digit is what number needs to be added to this total to make the next multiple of 10

In our case, we’d need to add 3 to make 60

therefore

The check number is 3

Solve the formula A = lw for l.
dybincka [34]

To solve A =lw for l it means you want l on one side of the equals and anything not l on the other side. How are l and w put together? They are multiplied. We undo that multiplying with dividing.

A = l * w

A / w = l to divide both sides by w.

Thus l = A / w.

Describe the transformation f(x) = 2x + 1 -&gt; g(x) = -8(x + 4) - 1
katrin2010 [14]

f(x) = 2x + 1; Paren graph = x;

The graph was shifted one unit up and stretched 2 times.

g(x) = -8(x+4) - 1 = -8x - 32 - 1 = -8x - 33

The graph was shifted 33 units down and stretched 8 times and flipped 180 degrees.

What is the area of a parallelogram whose verticles are A(-12, 2), B (6, 2), C(-2, -3), and D (-20, -3)?
Liono4ka [1.6K]

The area of the parallelogram will be 108 square units.

<h3>What is the area of the parallelogram?</h3>

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.

The vertices of the parallelogram are (x₁, y₁), (x₂, y₂), (x₃, y₃), and ( x₄, y₄).

Then the area of the parallelogram will be calculated as below:-

Area = 1/2 |[(x₁y₂ + x₂y₃ + x₃y₄+x₄y₁) - (y₁x₂ + y₂x₃ + y₃x₄+y₄x₁)]|

We have

(x₁, y₁) ⇒ (-12, 2)

(x₂, y₂) ⇒ (6, 2)

(x₃, y₃) ⇒ (-2, -3)

(x₄, y₄) ⇒ (-20 , -3 )

Then the area will be

Area = 1/2[{(-12) x (2) + (6) x (-3) + (-2) x (-3) + (-20 x 2 )} – {(2) x (6) + (2) x (-2) + (-3) x (-20) + ( -3 ) ( -12 )}]

Area = 108 / 2  

Area = 54 square units.

Therefore, the area of the parallelogram will be 108 square units.
