Step-by-step explanation:

2 x x = 2x  2 x -2 = -2.

Answer:

Option (A)

Step-by-step explanation:

From the given piecewise function that represent the amount of bill from number of units of electricity used is 'x' kWh.

b(x) = 0.10x   when x ≤ 200

         0.15(x - 200) + 20  when x > 200

For x = 400 kWh,

Function which represents the expenses of the bill,

b(400) = 0.15(400 - 200) + 20 [Since x > 200]

           = 0.15(200) + 20

           = 30 + 20

           = $50

Therefore, Option (A) will be the answer.

Answer:

3x(3x+2)

Step-by-step explanation:

1. Simplify: (4x2 - 2x) - (-5x2 - 8x).

Solution:

(4x2 - 2x) - (-5x2 - 8x)

= 4x2 - 2x + 5x2 + 8x.

= 4x2 + 5x2 - 2x + 8x.

= 9x2 + 6x.

= 3x(3x + 2).

Answer: 3x(3x + 2)

Answer:

$1,372.80

Step-by-step explanation:

I =Prt

I =(5,720)(0.06)(4)=1,372.8

x= -1.875 or x= -15/8

Step-by-step explanation:

-2(5x+8)=14+6x

-10x-16=14+6x

-16x-16=14

-16x=30

x= 30÷(-16)

x= -1.875 or -15/8

Answer:

120 pages can be printed in 1 hour.

Step-by-step explanation:

First divide 36 by 18 to figure out how many pages can be printed in a minute.

Like this: 36 pages ÷ 18 minutes = 2 pages in one minute.

Now, multiply 2 by 60 to figure out how many pages can be printed out in a hour.

Like this: 2 pages in one minute × 60 minutes ( one hour) = 120 pages in one hour can be printed.

Hope this helps!

Answer:

Step-by-step explanation:

From the picture attached,

There are two parallel lines intersected by three transverse lines.

m∠2 = 98°, m∠3 = 23°, m∠8 = 70°

a). Since ∠1 and ∠2 are linear pairs,

   m∠1 + m∠2 = 180°

   m∠1 + 98° = 180°

   m∠1 = 180 - 98

   m∠1 = 82°

b). m∠4 = m∠7 [Corresponding angles]

   m∠7 = 180° - (m∠2 + m∠3) [Property of a triangle]

            = 180 - (98 + 23)

            = 180 - 121

            = 59°

    m∠4 = m∠7 = 59°

c). m∠5 = 180° - (m∠3 + m∠4)

             = 180° - (23° + 59°)

             = 180° - 82°

             = 98°

d). m∠6 = 180° - (m∠7 + m∠8)

             = 180° - (59° + 70°)

             = 180 - 129

             = 51°

e). m∠7 = 59° [Calculated in part b]

f). m∠9 = 180° - (m∠4 + m∠8) [Property of a triangle]

            = 180° - (59 + 70)°

            = 180 - 129

            = 51°

g). m∠10 = 180° - m∠9

               = 180 - 51

               = 129°
