Actually Welcome to the Concept of the linear equations.
here, given value of x = 8 ,we substitute it to get the value of y,
so ,
5(8)-2y= 30
=> 40 - 2y = 30
=> -2y = -10
=> y = 5
hence the value of y = 5
=====> (8,5)
Answer:
r = -6, -1
Step-by-step explanation:
r^2 + 7r+6 =0
Factor
What 2 numbers multiply to 6 and add to 7
6*1 =6
6+1 =7
(r+6) (r+1) =0
Using the zero product property
r+6 =0 r+1 =0
r = -6 r=-1
Answer:

pls mark me brainliest!!!
Answer:
4 balloons
Step-by-step explanation:
3:6= 1:2
2*3= no. of guest, 1*3= no. of balloons
SO
2*4 (8)= number so guests, and 1*4 (4)= number of balloons
6x216 multiply them and u get 1296 then calculate the square root and your answer is 36
