I need to find A and C
Novay_Z [31]

if we take a look of the graph, let's notice that

AC = 4x + 4

AB = 14

BC = 3x - 4

now, AC = AB + BC,


\bf AC=AB+BC\implies AC-BC=AB\implies \stackrel{AC}{(4x+4)}-\stackrel{BC}{(3x-4)}=\stackrel{AB}{14}
\\\\\\
4x+4-3x+4=14\implies x+8=14\implies x=6
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
AC=4(6)+4\implies \boxed{AC=28}

If f(x) and g(x) are quadratic functions but (f+g)(x) produces true graph below, hutch statement must be true ?
alexgriva [62]

Answer:

A. the leading coefficients of f (x) and g (x) are opposites

Step-by-step explanation:

A. the leading coefficients of f (x) and g (x) are opposites

A quadratic function in its generic form is:

 f (x) = ax2 + bx + c

 g (x) = dx2 + ex + f

 The sum of the functions is:

 (f + g) (x) = (a + d) x2 + (b + e) x + (c + f)

 For the function to be linear necessarily:

 a = -d

Suppose an experiment consists of randomly drawing a marble out of a bag and replacing the marble. the bag contains 3 yellow mar
Savatey [412]
Hi there!

Since the yellow marbles to the radio of total marbles is 3/15,

3/15 = 5

We need to divide the total amount is times the marble is drawn by the ratio.

20 ÷ 5 = 4

So, the yellow marble would be drawn 4 times.

Hope this helps!

What are the zeros of the polynomial function? <br><br> F(x)= x^2 + 12x +20
vampirchik [111]

Answer:

<h2>x = -2 and x = -10</h2>

Step-by-step explanation:

F(x)=x^2+12x+20\\\\\text{The zeros:}\\\\F(x)=0\iff x^2+12x+20=0\\\\x^2+2x+10x+20=0\\\\x(x+2)+10(x+2)=0\\\\(x+2)(x+10)=0\iff x+2=0\ \vee\ x+10=0\\\\x+2=0\qquad\text{subtract 2 from both sides}\\\boxed{x=-2}\\\\x+10=0\qquad\text{subtract 10 from both sides}\\\boxed{x=-10}
