What is the answer to this equation using substitution x+y=1

FromTheMoon [43]

{ x + y = 1 * ( - 2 )
2 x + 3y = -4

- 2 x - 2 y = - 2
2 x + 3 y = - 4
_______________
y = - 6

Subsititute y = - 6
<span>
2 x + 3 y = - 4

2 x + 3 * (-6) = -4

2 x - 18 = - 4

2 x = - 4 + 18

2 x = 14

x = 14 / 2

x = 7

The solution to the system of equations are:

x = 7 and y = - 6

Find the domain of f/g

san4es73 [151]

Answer:

C. All real numbers except 3/4

Step-by-step explanation:

We are given

$f(x)=3x^2+x^4+2$

$g(x)=4x-3$

Firstly, we will find f/g

$\frac{f}{g}=\frac{3x^2+x^4+2}{4x-3}$

Domain:

We know that domain is all possible values of x for which any function is defined

so, we know that denominator of any function can not be zero

so, firstly we set denominator =0

and then we can solve for x

$4x-3=0$

Add both sides by 3

$4x-3+3=0+3$

$4x=3$

$x=\frac{3}{4}$

so, this function is defined for all values of x except at

$x=\frac{3}{4}$

Domain will be

All real numbers except 3/4

Number 8 please! Please!

MariettaO [177]

Well we know she filled up her car 11 times each with 14 gallons.

All we have to do is multiply 11 by 14
11 x 14 = 154

Now the question says to estimate. And our answer can be rounded down to 150 gallons.

So your answer is..
B.) 150 gallons.

Good Luck! :)
