Answer 1

@satellite73

Answer 2

just plug ( p ,p+2) in the equation of line and solve for p !

Answer 3

What would be your answer?

Answer 4

first solve it your own and then show your work and i'll tell you are you correct or wrong ?

Answer 5

-3 was my answer :)

jost post it !

Answer 11

What is the gradient of line AB from the previous question?

Answer 12

I said 3/4

Answer 13

@mayankdevnani

Answer 14

you are correct !

Answer 15

I am??

Answer 16

yeah

Answer 17

explain how u did it

Answer 18

I said : You need to rearrange in to the form y=mx+c, where m is the gradient and c is the y intercept. In this case the rearranges equation is y=(3/4)x+(5/4)

Answer 19

\[\large \bf ax+by+c=0\]
let this be a equation of line.
formula for finding slope of this line :-
\[\large \bf slope=\frac{-a}{b}\]

Answer 20

just plug the values in it and solve !

Answer 21

A geometric series has first term 80 and common ratio 1/2. What are the next two terms?

Answer 22

I said 40 and 20

Answer 23

show your work !

Answer 24

Multiply the first term by 1/2 to get the second term (40) and do it again to get the third (20).

Answer 25

correct !
