Which two points have a undefined slope A.(-1, 1) and (1, -1)

B.(-2, 2) and (2,2)

C.(-3, -3) and (-3,3)

D.(-4,-4) and (4, 4)

Answers

Answer:

C.(-3, -3) and (-3,3)

Step-by-step explanation:

When we have a vertical line the slope is undefined.

That means the x values stay the same

C.(-3, -3) and (-3,3)

This has the same x values

m = (y2-y1)/(x2-x1)

   =( 3- -3)/(-3 - -3)

   (3+3)/(-3+3)

   6/0

  undefined

Answer: C

Step-by-step explanation:

The cost of a ticket to the circus is $19.00 forchildren and $42.00 for adults. On a certain day,
attendance at the circus was 1,700 and the total
gate revenue was $55,300. How many children and
how many adults bought tickets?​

Answers

Answer:

The number of tickets bought is 1000 adults tickets and 700 children were present  

Explanation:

Let the number of children and adults present in the circus be x and y respectively

According to question,

Then, x + y = 1700  ……………..equation (1)

And, cost of ticket to circus for children and adult be 19, 42 respectively

Totalcost of ticket;

for adults = 42y; for children = 19x

19x + 42y = 55300  …………………equation (2)

Multiplying equation (1) by 19

19x + 19y = 32300  ……………… eqn (3)

Subtracting equation 1 and 3, we get

23y = 23000

y = 1000

putting this value in eq (1), we get x = 700

Therefore, 1000 adults and 700 children were present.

Help!!!! How do I solve this

Answers

Answer:

-11

Step-by-step explanation:

So, using the fact that one x intercept is 7, and the vertex is (-2,-4), we can solve for the other x intercept. While there are many ways to solve this, the way I prefer to do it is to realize that the x intercepts are the same distance away from the vertex. this means that if the vertex is at x = -2, and one x intercept is at x = 7, the other will be at -11, as 7+2 = -2+11.
I’m pretty sure that the other x-intercept is -7

16 2/3% of what number is 45

Answers

convert 16 and 2/3 to impropoer
16 and 2/3=50/3
percent means parts out of 100
16 and 2/3%=(16 and 2/3)/100=(50/3)/100=50/300=1/6

'of' means multiply

therefor we translate
