Answer:

y=7.51

Step-by-step explanation:

First, you have to simplify one of the equations down

3x-y=4

y=-4+3x

Second, you insert the value of y into the other equation and then solve for x

9x+5(-4+3x)=8

9x-20+15x=8

24x=28

x=1.17

Last, insert the value of x into the original equation and then solve for y

y=4+3(1.17)

y=7.51

F(x) = x^2 - 3x+ 5 g(x) = 2x^2 - 4x - 11 what is h(x) = f(x) + g(x)

iogann1982 [59]

Hey there! :)

Answer:

h(x) = 3x² - 7x - 6

Step-by-step explanation:

Calculate h(x) by adding the two polynomials:

h(x) = f(x) + g(x):

h(x) = x² - 3x + 5 + 2x² - 4x - 11

Combine like terms:

h(x) = 3x² - 7x - 6

What is the factored form of x^3-1

polet [3.4K]

Answer:

the factors of x^3-1 are $x^3 -1 = (x-1) (x^2 +x+1)\\$

Step-by-step explanation:

We need to find factors of x^3 -1

$x^3-1 \\(x)^3 -(1)^3\\We \,\, know\,\, a^3 -b^3 = (a-b) (a^2 +ab + y^2) \\So, \,\, using\,\, the \,\, formula\,\,\\Here\,\, a= x \,\,and\,\, b= 1\\(x)^3 -(1)^3 = (x-1) (x^2 +x+1)\\$

So, the factors of x^3-1 are $x^3 -1 = (x-1) (x^2 +x+1)\\$

Of the 2223 people on titanic, only 706 reached New York. What percent of people reached New York?

Liula [17]

For this, we can first find the decimal value by dividing 2223 from 706. Therefore, if we do 706/2223, we get .31759. Do find the percentage, simply multiply by 100. Now, we have 31.759% Therefore, 31.759% of the people on the Titanic reached New York.

Answer:
31.759%

Hope this helped!! :D
