DeShaun and Vu are brothers who like to make bets about the outcomes of different contests between them. Before the last bet, the ratio of the amount of Deshaun's money to the amount of Vu's money was 4:7. Vu lost the latest competition, and now the ratio of the amount of Vu's money is 8:3. If Vu had $280 before the last competition, how much does Vu have now that he lost the bet?

Answers

Answer: Vu have $60.

Step-by-step explanation:

Given: Before bet, the ratio of the amount of Deshaun's money to the amount of Vu's money was 4:7.

Let Deshaun's money =4x and Vu's money = 7x

If Vu had $280 before the last competition, then

7x = 280

⇒ x = 40   [Divide both sides by 7]

Deshaun's money = 4x = 4 x 40 = $160

After Vu lost bet, ratio becomes 8:3.

Let Deshaun's money = 8y and Vu's money = 3y

For Deshaun,  8x = 160 ⇒ y = 20  [divide both sides by 8]

Vu's money  = 3 (20)=$60

Hence, Vu have $60.

Find the zeros of the function algebraically.
f(x) = 16x4 − 49x2

Answers

Answer: Plz mark me brainlest

Step-by-step explanation:

Just Simply Use Identity:

 

  a^2 - b^2 = ( a+b) ( a-b)

   Then:

     ( 49X^4 - 36 X^2) = 0

       (7 X^2 + 6 X) ( 7X^2 - 6X) =0

       7X^2 + 6X = 0, then           X( 7X +6) =0    X=0,  7x +6 =0   X = -6/7

           7X^2 -6x =0                   X( 7x - 6) =0   X =0   7x -6 =0    X =6/7

Pull out a factor of x² from f(x) :

16x⁴ - 49x² = x² (16x² - 49)

Now write it as a difference of squares, then factorize:

16x⁴ - 49x² = x² ((4x)² - 7²)

16x⁴ - 49x² = x² (4x - 7) (4x + 7)

Set this equal to 0 and solve for x :

x² (4x - 7) (4x + 7) = 0

x² = 0   or   4x - 7 = 0   or   4x + 7 = 0

x = 0   or   x = 7/4   or   x = -7/4

sin^2x + sin^2x + cos²x

Answers

Answer:

Answer:

A. 2 sinx cosx - 1 + 2 sin^2 x.

Step-by-step explanation:

sin2x = 2 sinx cosx

cos2x = cos^2x - sin^2x

So sin2x - cos2x =  2 sinx cosx - ( cos^2x - sin^2x)

But cos^2 x = 1 - sin^2 x, so we have:

2 sinx cosx - (1 - sin^2 x - sin^2x)

= 2 sinx cosx - 1 + 2 sin^2 x.

the initial fee for the installation, $35
the initial fee for the installation, $100
the cost per hour of installation work, $35
the number of hours to complete the installation, x

Answers

Answer:

the cost per hour of installation work, $35

Step-by-step explanation:

y = 35x + 100

the slope of a function is the coefficient of x, therefore, it is 35. $100 is the initial fee, since it ia the y intercept, and $35 is the cost per hour. y is the total amount, and x is the number of hours. Therefore, the only possible answer is the third choice,

$1350 is the total balance after 3 months and $450 is the amount he has payed in those 3 months

2.) 450/3=150

You do 450/3 to find how much he is paying per month. If you want to check your work do 1800-1050=750 then do 750/5=150

Answer:

x = 110

Step-by-step explanation:

Assuming you require the value of x

The sum of the external angles of a triangle = 360°

The 3 angles shown are external angles.

Subtract the sum of the 2 given angles from 360 for x

x = 360 - (140 + 110) = 360 - 250 = 110
