Answer:

\huge\boxed{B. [1,2,3,........]}

Step-by-step explanation:

9x - 4 < 13 x - 7

Combining like terms

=> -4 + 7 < 13x-9x

=> 3 < 4x

Dividing both sides by 4

=> x > \frac{3}{4}

=> x > 0.75

This means that x can be any number <u>that is greater than 0.75</u>

So, The solution set = [1,2,3,........]

Find two positive real numbers with the given sum whose product is a maximum. The sum of the first and twice the second is 24
Elenna [48]
Y+2x=24
product is max
xy=max

we have
y+2x=24
minus 2x both sides
y=24-2x
sub that for y in xy=max
(24-2x)(x)=max
-2x^2+24x=max
we have a parabola opening down
the coordinates of the vertex is our answer

the x value of the vertex is -b/2a where
ax^2+bx+c=y

-24/2(-2)=-24/-4=6
xvalue=6

we can just sub
y=24-2x
y=24-2(6)
y=24-12
y=12
the numbers are 6 and 12
the product is 72



the numbers are 6 and 12

Classify the events as dependent or independent. the events of getting two aces when two cards are drawn from a deck of playing
Thepotemich [5.8K]
The events are dependent. 

When the first card is not replaced, you change the probability of the second card.  At the very least, you have changed the total number of cards to draw from.
