Mathematics
1 answer:
Lyrx [107]3 years ago
4 0

Answer:

D. -3x+3y

Step-by-step explanation:

Start by distributing the -3 to each term in the parentheses:

-3(x)+(-3)(-y)

Here are some multiplication sign rules that will make this problem easier:

- - make a +

- + make a -

+ - make a -

+ + make a +

-3x+3y (note that since both 3 and y are negative, they make a positive)

Write this in a variable expression: feet in y yards
sasho [114]

We know that; 1 foot = 2/3 yards and 1 yard = 3 feet

Since we are trying to find how many "yards", we can write the equation like this:

y = f/3

f = foot

What is the value of x?
Dafna1 [17]

Answer:

28


Step-by-step explanation:

We use the concept of similarity to find the value of X.

Δ APR ≡  ΔCDR

∴ AR/CR = PR/DR

   (10+x)/x = (15+42)/42

42(10+x) = 57x

420 + 42x = 57x

57x - 42x = 420

15x = 420

x = 420/15

  = 28

Which system of equations can be used to find the roots of the equation 12 x 3-5x=2 x 2+x+6
kirill [66]

Answer:

Option (a) is correct.

The system of equation becomes

y=12x^3-5x\\\\ y=2x^2+x+6

Step-by-step explanation:

Given : Equation  12x^3-5x=2x^2+x+6

We have to construct a  system of equations that  can be used to find the roots of the equation 12x^3-5x=2x^2+x+6

Consider the given equation 12x^3-5x=2x^2+x+6

To construct a system of equation put both sides of the given equation equal to a same variable.

Let the variable be "y", Then the equation 12x^3-5x=2x^2+x+6

becomes,

12x^3-5x=y=2x^2+x+6

Thus, The system of equation becomes

y=12x^3-5x\\\\ y=2x^2+x+6

Option (a) is correct.
