Answer:

The slope is 1

Step-by-step explanation:

Do the slope formula y2-y1/x2-x1

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:

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°

Answer:

[tex]E=\frac{mv^2}{2}[/tex]

Step-by-step explanation:

[tex]m=\frac{2E}{v^{2} }[/tex]

Multiply [tex]v^2[/tex] to both sides:

[tex]m*v^2=\frac{2E}{v^{2} } *v^2[/tex]

[tex]mv^2=2E[/tex]

Switch sides:

[tex]2E=mv^2[/tex]

Divide both sides by 2:

[tex]E=\frac{mv^2}{2}[/tex]

Answer:

[tex]x^3-5x^2+10x-14[/tex]

Step-by-step explanation:

[tex]\left(2x^3-5x^2+3x-10\right)-\left(x^3-7x+4\right)[/tex]

Remove brackets:

[tex]2x^3-5x^2+3x-10-x^3+7x-4[/tex]

Group similar terms together:

[tex]2x^3-x^3-5x^2+3x+7x-10-4[/tex]

Add/Subtract the terms:

[tex]x^3-5x^2+10x-14[/tex]

Answer:

Step-by-step explanation:

( 2X³ - 5X² + 3X - 10 ) - ( X³ - 7X + 4 )

2X³ - 5X² + 3X - 10 = X² - 10

X³ - 7X + 4 = - 7X² + 4

X² - 10 - - 7X² + 4 =

X² - 10 + 7X² + 4 =

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:

100n+250t

Step-by-step explanation:

cost of the1 one day pass=100

cost of n one day passes=100n

cost of the 1 three day pass=250

cost of t three day passes=250t

Total sale= 100n+250t

The expression for the total ticket sales if (n) one day passes and (t) three day passes are sold is n + t = $350.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

Cost of one-day passes, n = $100

Cost of three-day passes, t = $250

So, Total tickets sold = Cost of one-day passes + Cost of three-day passes

⇒ Total tickets sold = n + t

⇒ n + t = $100 + $250

⇒ n + t = $350

which is the required expression for total tickets sold.

Thus, the expression for the total ticket sales if (n) one day passes and (t) three day passes are sold is n + t = $350.

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).

The difference between the expression and an equation is explained below:

The equation represents the mathematical value while the expression could include the numbers, letters, etc. The expression should be treated as phrases while the equations are considered to be complete sentences. The expression does not show any kind of relations while the equation should show the relationship.

In this way, it should be differentiated.

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.
