If f(x) = x^3, which of the following describes the graph of f(x + 2)?

2 answers:

6 0

This problem is trying to be confusing on purpose the way its written, so ill do my best to explain. f(x+2) is a silly way of saying that your equation is translates up two units, the "+2" is again "b" in the equation y=mx+b
so its telling you to basically write your equation as y=x^3+2. they will also try to confuse you by showing you this,
y=(x+2)^3, which is a horizontal translation, twice to the left, so don't be fooled. all in all with your final equation as y=x^3+2, you are left with a vertical translation upwards of 2 : )

Suppose a normal distribution has a mean of 50 and a standard deviation of 3. What is P(x≤53)?

Vera_Pavlovna [14]

Answer:

Step-by-step explanation:

Use the formula to find the z-score, then go to the table that will give you the probability that the value is less than this z-score.

$z=\frac{53-50}{3}=1$

The probability that the value lies to the left of 1 on a standard bell curve is 84.1345%, or 84%, the third choice down.

Answer:

y= (-7/16)

Step-by-step explanation:

Multiply (3/4)(1/4)= (3/16)

y= (3/16)-(5/8)

y= (-7/16)

I hope this is right, im not 100% sure

Solve each system by graphing. If the solution is not unique, identify the system as “inconsistent” or “dependent”

lapo4ka [179]

Answer:

therefore the solution of the system of equations is (x,y) = (4,2)

the solution is unique and therefore the the system is neither "inconsistent" nor "dependent"

Step-by-step explanation:

i) x + 2 = 6 $\Rightarrow$ x = 4

ii) x - y = 2 $\Rightarrow$ 4 - y = 2 , therefore y = 4 - 2 , therefore y = 2

iii) therefore the solution of the system of equations is (x,y) = (4,2)

iv) the solution is unique and therefore the the system is neither "inconsistent" nor "dependent"
