Hey there!!
Given equation :
( x - 1 ) / 4 = ( x + 2 ) / 3
First step we will need to take is to cross-multiply. In cross-multiplication, we will have t multiply the denominator with the numerator on both the sides. In this case, we will have to multiply 4 with x + 2 and 3 with x - 1.
... 4 ( x + 2 ) = 3 ( x - 1 )
... 4x + 8 = 3x - 3
Subtract 3x on both sides.
... x + 8 = -3
Subtract 8 on both sides
... x = - 11
Hope my answer helps!
it could be 2.2 because every 5 you get 2 so it would be 10 and 4 so when y=6 then x should be 2.2.
Y=4x+2. To get slope you use 6-2/1-0. Which gives you 4. You then put that in point slope form.
Answer:
Option A is correct.
Step-by-step explanation:
Given: 
; 
for n = 2
= 
for n =3
= 
Simlarly , for n =4
= 
and so on...
Common ratio(r) states that for a geometric sequence or geometric series, the common ratio is the ratio of a term to the previous term.
we have; 
Now; by recursive formula for geometric series:
where 
is the first term and r is the common ratio:
Substitute the value of and 
we have;
therefore, the explicit rule for the geometric sequence is;
Y = 32 - 1/2x
example : lets say that there r 30 students.....x = 30
y = 32 - 1/2(30)
y = 32 - 15
y = 17 cups......so 17 cups remain
