Yes it will be the yellow marble because there is least amount of them.

2/9 chances of getting a yellow because 4 + 3 + 2 is 9 and there is 2 yellow marbles in the bag.

<h2>Answer:</h2>

The vertex of the function is:

(-2,-2)

<h2>Step-by-step explanation:</h2>

We are given a absolute value function f(x) in terms of variable "x" as:

$f(x)=-|x+2|-2$

We know that for any absolute function of the general form:

$f(x)=a|x-h|+k$

the vertex of the function is : (h,k)

and if a<0 the graph of function opens downwards.

and if a>0 the graph of the function opens upwards.

Hence, here after comparing the equation with general form of the equation we see that:

a= -1<0 , h= -2 and k= -2

Since a is negative , hence, the graph opens down .

Hence, the vertex of the function is:

(-2,-2)

It cost $10.50 to buy 3 medium pizzas. How much does it cost to buy 10 medium pizzas?

melomori [17]

It would cost $35 because 10.50 divided by 3 = 3.5x10=35

A line crosses through the point (3,10) and another point can be found on the line by going right 2 and down 7. find slope and y

DerKrebs [107]

Answer:

y = $\frac{-7x}{2}+\frac{41}{2}$

Step-by-step explanation:

We are given the point (3, 10).

The second point is 2 on the x-axis and -7 on the y-axis. So our second point is: (3 + 2, 10 - 7) which is (5, 3).

Our formula for slope is m = $\frac{rise}{run}$ = $\frac{y2-y1}{x2-x1}$

So, our equation would be $\frac{3-10}{5-3}$ = $\frac{-7}{2}$

Using the standard formula of a line, y = mx + b, we can substitute for the slope, m.

y = $\frac{-7x}{2}$ + b

Now, we can substitute a point on the line to determine the y-intercept:

Using the point (3, 10),

10 = $\frac{-7(3)}{2}$ + b

b = 10 + $\frac{21}{2}$

b = $\frac{41}{2}$

So our full equation is: y = $\frac{-7x}{2}+\frac{41}{2}$

Please help!!!!!!!!!!!

Assoli18 [71]

<u>Let's take this problem step by step:</u>

<u>To find the ordered pair of the system:</u>

⇒ must set both equations equal to each other

⇒ and solve for 'x'

<u>Let's solve:</u>

$x^2-2x+3=-2x+19\\x^2-2x+2x+3-19=0\\x^2-16=0\\(x+4)(x-4)=0$

<u>Let's find the x-values:</u>

$(x-4)=0\\x=4\\\\(x+4)=0\\x=-4$

<u>Let's find f(x)'s value for each 'x':</u>

$x=4\\f(4)=-2(4)+19=-8+19=11\\\\x=-4\\f(-4)=-2(-4)+19=8+19=27$

<u>Answer: (4, 11), (-4,27)</u>

Hope that helps!

How <br> do you write (-∞, 8) or (10, ∞) as an inequality?

ahrayia [7]

Your answer would be, To write, (−∞,8), or (10,∞), ==> x < 8 or, x > 10

(-∞, 8) or (10, ∞)

Solution: ==> - 10 . ∞ + 8 . ∞ or, x < 8 or, x > 10

Steps:

(-∞, 8) or (10, ∞) ==> - 10 . ∞ + 8 . ∞

(-∞, 8) . (10, ∞)

Computing dot product of two Vectors:

( X1, Xn) . ( Y1, Yn) = Σ^n^i = 1X^iY^i

= ( - ∞) . 10 + 8 . ∞

Simplify:

( - ∞) 10 + 8 . ∞

- 10 . ∞ + 8 . ∞

( - ∞) . 10 + 8 . ∞

Remove Parenthesis:

( - a) ==> - a

- ∞ . 10 + 8 . ∞

==> - 10 . ∞ + 8 . ∞

==> (- 10 . ∞ + 8 . ∞) ==> - 10 . ∞ + 8 . ∞

( ==> - 10 . ∞ + 8 . ∞)

Remove Parenthesis:

( a) = a

==> - 10 . ∞ + 8 . ∞

Therefore, (-∞, 8) or (10, ∞) as an inequality, Answers are, ==>

- 10 . ∞ + 8 . ∞ or, x < 8 or, x > 10

Check:

(-∞, 8) or (10, ∞)

==> x < 8 or, x > 10

Solution:

x < 8 or, x > 10

Interval Notation:

[ x < 8 or, x > 10 ==> (-∞, 8) ∪ (10, ∞) ]

Steps:

x < 8 or, x > 10

x < 8 : x < 8

x < 8

x < 8

x < 8

x > 10 : x > 10

x > 10

x > 10

x > 10

Combine The Ranges:

x < 8, or x > 10

Hope that helps!!!!! : )
