3x = 27 + Зу
3х - 10у = 27

please explain how you got the answer.

Hi there!

Your answer is:

Y= 0

X= 9

Step-by-step explanation:

3x=27+3y

3x-10y=27

Solve one of them for Y

I chose the first equation

3x=27+3y

-27

3x-27=3y

/3

x-9 = y

NOW, plug y in the second equation!

3x-10y=27

y= x-9

3x-10y=27

3x-10(x-9) = 27

Solve for x!

3x-10x+90 = 27

-7x + 90 =27

-90

-7x = -63

/-7

x= 9

FINALLY, plug back in x for y equation

y=x-9

x=9

y=9-9

y=0

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
