Answer:

29. (5,0) and (-7/2,0)

30. (-1,0) and (5/7,0)

Step-by-step explanation:

29. y=2x² - 3x - 35

y = (x-5)(2x+7)

y is 0 at x = 5 and -(7/2)

31: y=-7x² - 2x + 5

y = -(x+1)(7x-5)

y is 0 at -1 and 5/7

See the attached graph.

Answer:

I think it goes like this : 20:4=5 so there's five monsters in the room

Step-by-step explanation:

if that's the case of this question it should go like this:

9(rooms)×5(monsters per room)= 45 monsters

30(monsters):5(monsters per room)=6 rooms

13(rooms)×5(monsters per room)=65 monsters

35(monsters):5(monsters per room)=7 rooms

I hope you do well in your assignment.

I hope I helped at least a little!

2. The table below shows that the distance d varies directly as the time t. Find the constant of variation and the equation which describes the relation.

<h2><u>Solution</u>:-</h2>

Since the distance d varies directly as the time t, then d = kt.

Using one of the pairs of values, (2, 20), from the table, substitute the values of d and t in d = kt and solve for k.

$\sf{\rightarrow{d = kt}}$

$\sf\rightarrow{20 = 2k }$

$\sf\rightarrow{K= \frac{20}{2} }$

$\sf\rightarrow{K={\color{magenta}{10}}}$

<h2><u>Answer</u>:-</h2>

Therefore, the constant of variation is 10.
