Answer:

B. The slope of f(x) is greater than the slope of g(x)

Step-by-step explanation:

The graph of f(x) has a "rise" of -2 for a "run" of 1, so its slope is -2.

The coefficient of x in g(x) is -7, so its slope is -7.

-2 is greater than -7, so the slope of f(x) is greater than the slope of g(x).

___

The graph of g(x) is steeper by a factor of 3.5, so one could argue it has the greater slope. However, we're comparing negative numbers, so the negative number with the larger magnitude is considered to be less than the negative number with the smaller magnitude. Legitimate disagreement is possible.

Evaluate f(x)=-x^2+1 for x=-3

Wewaii [24]

For this case we have a function of the form $y = f (x)$ , where:

$f (x) = - x ^ 2 + 1$

We must evaluate the function for $x = -3$

Then we have to replace:

$f (-3) = - (- 3) ^ 2 + 1\\f (-3) = - 9 + 1$

Different signs are subtracted and the sign of the major is placed:

$f (-3) = - 8$

ANswer:

$f (-3) = - 8$

matrenka [14]

Say x = 12 and y = 4
12 - 4 = 8

Number 1
2(12) - 4(4) = 8
24 - 16 = 8
Number 1 is your Answer

Survey data indicate that 42% of customers at Mega Hit video rental stores subscribe to premium movie channels through their cab

omeli [17]

Answer:

P=0.17

Step-by-step explanation:

If A and B are dependent events, then we have a Rule of Addition:

$P(A\cup B)=P(A)+P(B)-P(A\cap B)$

Let A represent event that customer at Mega Hit is subscribed to premium movie channels while B represent event that customer at Mega Hit owns a DVD, so, we get the following:

$P(A)=0.42\\P(B)=0.31\\P(A \cup B)=0.56\\\\$

We need to find $P(A \cap B)$ or probability that a randomly selected Mega Hit customer both owns a DVD and subscribes to a premium movie channels.

Using Rule of Addition, we get:

$0.56=0.42+0.31-P(A \cap B)\\\\0.56=0.73-P(A\cap B)\\P(A\cap B)=0.73-0.56\\P(A\cap B)=0.17$

So, the required probability is 0.17.

How do you substitute x+7y=0 into 2x-8y=22

Grace [21]

First solve for x in the first equation

x + 7y = 0
x = -7y

since x = -7y we can substitute -7y into the other equation wherever there is an x

2x - 8y = 22
2(-7y) - 8y = 22
-14y - 8y = 22
-22y = 22
y = -1

Now let's substitute -1 back into either of the original equations so we can solve for x

x + 7y = 0
x + 7(-1) = 0
x - 7 = 0
x = 7

So your solution set is

(7, -1)
