Answers

Answer 1

Answer:

f(4) = -6, g(-3) = 36

Step-by-step explanation:

To find f(#) or g(#), plug the number into each x of the equation.

f(x) = -2x + 2

f(4) = -2(4) + 2

Simplify the parentheses by multiplying.

f(4) = -8 + 2

Add.

f(4) = -6

g(x) = 3x² - 3x

g(-3) = 3(-3)² - 3(-3)

Simplify the exponent first.

g(-3) = 3(9) - 3(-3)

Simplify the parentheses by multiplying.

g(-3) = 27 + 9

Add.

g(-3) = 36

the marked price of an article , which is brought it for Rs 1280 is 25% above the cost price. if the discount is allowed and customer brought it for Rs 1540 including 10% Vat , what is the discount percent?​

Answers

Answer:

I corrected my mistakes.

The discount percentage when the marked price of an article , which is brought it for Rs 1280 is 25% above the cost price should be 12.5%.

Calculation of the discount percentage:

Since the cost price is 1280

Now the market price be like

= 1280 + 25% of 1280

= 1600

Now the selling price is

[tex]= 1540\div 1.1[/tex]

= 1400

Now the discount percentage should be

[tex]= (1600 - 1400) \div 1600[/tex]

= 12.5%

hence, The discount percentage when the marked price of an article , which is brought it for Rs 1280 is 25% above the cost price should be 12.5%.

What is the value of y?

Answers

Answer:

y = 44°

Step-by-step explanation:

= 180 - 88

= 92°

y + y + 92° = 180°

2y = 180° - 92°

2y = 88°

y = 88/2

y = 44°

All 3 angles add up to 180 degrees...if one angle is 88 degrees, the other 2 together must add up to 92. The diagram shows that the other 2 angles are the same, so divide 92 in half (2 equal parts)...92/2=46.
So both of the other angles (y) measure 46 degrees.

8.44 = 34.6 + 4h/5
Helpppppp!!!

Answers

Answer:

h = -32.7

Step-by-step explanation:

8.44 = 34.6 + 4h / 5

-26.16 = 4h/5 (First off we subtract 34.6 from each side, to make it easier to solve)

-26.16 = 0.8h (Then, we turn 4h/5 into 0.8h since 4h / 5 = (4/5)h.)

-32.7 = h (Divide both sides by 0.8..)

h = -32.7 (And voila!! Your answer is right there!)

Answers

Answer:

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

-6*x-(84)=0

Step by step solution :

STEP 1: Pulling out like terms

1.1     Pull out like factors :

  -6x - 84  =   -6 • (x + 14)

Equation at the end of step 1:

STEP 2: Equations which are never true

2.1      Solve :    -6   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2      Solve  :    x+14 = 0

Subtract  14  from both sides of the equation :

                     x = -14

One solution was found :

x = -14

Answer: i think u should divide 84 by 6 to keep x alone the answer is x=14

but the answer depends on the sign of the variable .

The tortoise and the hare are having a race.In this tale,the tortoise moves 50 ft per hr while the hare moves at 259ft per hour. The tortoise takes 8hrs longer than the hare to finish. a. Let t represent the unknown time in hours that it took the hare to complete the race,
Write an expression (not an equation!) representing the time it took the tortoise to finish
the race.
b. Write two equations that represent the race, one for the hare and one for the tortoise.
c. What is the distance of the race?

Answers

Answer:

Step-by-step explanation:

1). Let the distance of the race = x feet

   Speed of hare = 250 feet per hour

   If it takes the time to complete the race = t hours

   Since, Speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]

   250 = [tex]\frac{x}{t}[/tex]

   t = [tex]\frac{x}{250}[/tex]

2). Speed of tortoise = 50 feet per hour

   Time taken by the tortoise [tex]t_1=\frac{x}{50}[/tex]

   So the equations will be,

   t = [tex]\frac{x}{250}[/tex] -------(1)

   [tex]t_1=\frac{x}{50}[/tex] -------(2)

3). Since, tortoise took 8 hours longer than hare,

   [tex]t_1[/tex] - t = 8

   [tex]\frac{x}{50}- \frac{x}{250}=8[/tex]

   [tex]\frac{(5-1)x}{250}=8[/tex]

   [tex]\frac{4x}{250}=8[/tex]

   x = [tex]\frac{250\times 8}{4}[/tex]

   x = 500 feet
