Hello!

An unknown or changeable quantity is a variable. We can write these expressions below and see which one has a variable.

A. 15

B. 60(5)

C. 2p

D. $3.76

As you can see, we do not know how many pages are in the book. Therefore, our answer is C.

I hope this helps!

Answer:

  see attached

Step-by-step explanation:

Most of this exercise is looking at different ways to identify the slope of the line. The first attachment shows the corresponding "run" (horizontal change)  and "rise" (vertical change) between the marked points.

In your diagram, these values (run=1, rise=-3) are filled in 3 places. At the top, the changes are described in words. On the left, they are described as "rise" and "run" with numbers. At the bottom left, these same numbers are described by ∆y and ∆x.

The calculation at the right shows the differences between y (numerator) and x (denominator) coordinates. This is how you compute the slope from the coordinates of two points.

If you draw a line through the two points, you find it intersects the y-axis at y=4. This is the y-intercept that gets filled in at the bottom. (The y-intercept here is 1 left and 3 up from the point (1, 1).)

A ball is thrown into the air. The height in feet of the ball can be modeled by the equation, h(t) = −16t2 + 10t + 6 where t is
Lelechka [254]

A function assigns the value of each element of one set to the other specific element of another set. The correct option is D.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

The time at which the ball will hit the ground is,

h(t) = −16t² + 10t + 6

0 = -16t² + 10t + 6

8t² - 8t + 3t - 3= 0

8t(t-1)+3(t-1) = 0

(8t+3)(t-1)=0

t = -0.375, 1

Hence, the ball hit the ground at 1 second, while the function in intercept form can be written as h(t) = (−8t − 3)(2t − 2).

Thus, the correct option is D.

what is the equation to seven less than the product of twice a number is greater than 5 more than the same number
postnew [5]
<span>seven less than (-7) than the product of twice a number (2x) is greater than (>) five more than (+5) the same number (x)

2x-7>x+5
treat the > sign as an equals for now
2x-7=x+5
subtract x from both sides
x-7=5
add 7 to both sides
x=12
put the > sign back in
x>12</span>

Annie found that 57 students in her school knew French and 23 of those students knew Spanish, as well. There were 11 students wh
V125BC [204]

Answer:

Table C is the correct option.

Step-by-step explanation:

We are given,

Number of students which knew French = 57

Number of students which knew both French and Spanish  = 23

Number of students which knew Spanish but not French = 11

Number of students which knew neither French nor Spanish = 4

So, we get that,

Number of students not knowing French = 57 - 23 = 34

Hence, the table for the given situation is,

                              Knew Spanish    Did not know Spanish    Total

Knew French                  23                          34                         57

Did not know French      11                             4                           15

Total                               34                             38                        72

Thus, option C is correct.
