-2 is your answer

Step-by-step explanation:

First, you get 2/3 and distribute it into the parentheses that gives you

4-6x=16

Amanda's book bag is 0.10. Some of Amanda's pens are removed and replaced with pink pens. Her book bag still contains a total of

Marta_Voda [28]

Answer:

The number of pink pens can be 19 .

Step-by-step explanation:

Total Number of pens = 20

Let x be the number of pink pens

We are supposed to find If the probability of choosing a pink pen is close to 1, how many pink pens would you expect to see in Amanda's bag

Probability of choosing a pink pen = $\frac{\text{Number of pink pens}}{\text{Total Number of pens}}$

Probability of choosing a pink pen = $\frac{x}{20}$

ATQ

$\frac{x}{20}$ ≈1

x≈20

So, the number of pink pens can be 19 .

PLEASE help asap if u know the answer!!!! quadratic functions:vertex form thank you!!!

SOVA2 [1]

Answer:

The answer to your question is: third option, it's a parabola

Step-by-step explanation:

f(x) = (x + 4)²

f(x) = x² + 4

f(x) = (x - 4)² I think this is the right answer, because when get the vertex, the signs are changed, if the -4 is negative, it means that the graph must be located in +4.

f(x) = x² - 4

8(5-32) equal to and explain <br> please help

Gre4nikov [31]

You would use order of operations: PEMDAS
P(parenthesis) E(exponents) MD(multiplication/division) AS(addition/subtraction)
with MD and AS order doesnt matter.
8(5-32) you would start with inside the Parenthesis for "P" so (5-32)=(-27)
next you would go to the E but because you dont have an exponent you go to the next step with is the "MD" you have multiplication so next would be 8(-27) and 8 multiplied by -27 is: 8(-27)= -216
ANSWER: -216
