Answer:

x=-17,y=3

Step-by-step explanation:

x+y=-14

x=x

y=x+20

x+(x+20)=-14

2x+20=-14

2x=-14-20

2x=-34

x=-34/2

x=-17

y=-17+20

y=3

If f(x)=x^2 and g(x)=1÷2x+3 find g(f(-1))
gogolik [260]

ANSWER

g(f( - 1)) = \frac{1}{5 }

EXPLANATION

The given function is:

f(x) =  {x}^{2}

and

g(x) =  \frac{1}{2x + 3}

g(f(x)) = g( {x}^{2} )

g(f(x)) = \frac{1}{2{x}^{2} + 3 }

To find g(f(-1)), we substitute x=-1, to obtain;

g(f( - 1)) = \frac{1}{2{( - 1)}^{2} + 3 }

We simplify the square in the denominator to get,

g(f( - 1)) = \frac{1}{2+ 3 }

We now add the denominator to obtain;

g(f( - 1)) = \frac{1}{5 }

Twenty four over the quantity of 3 x minus two. Find f(−2).
TEA [102]
Answer:

f(-2) = -3

Explanation:

Not sure if those last couple numbers are answer choices, but I'm going to infer that they might be.

Twenty four over the quantity of 3 x minus two in standard form is:

f(x) = <span>24<span>3x−2</span></span>

Since the number in the ( ) = x, plug in for x using f(-2)

<span>24<span>3∗<span>(−2)</span>−2</span></span>

P E {M D} {A S} for where to solve first

Multiply the 3 and (-2):

<span>24<span>−6−2</span></span>

Add -6 and -2:

<span>24<span>−8</span></span>

Divide the rest:

f(-2) = -3

How to factor a trinomial x^2+11x+19
Tresset [83]

Answer:

this trinomial is prime, and cannot be factored.

Step-by-step explanation:

when expanding the equation, you multiply the last term by the first term's coefficient, and then find two factors that multiply to that product, and sum to the middle coefficient.

1 * 19 = 19

there are no factors that will multiply to 19 and sum to 11. thus, this polynomial is prime.
