Answer:
x = 9 y = -4
Step-by-step explanation:
4x + 3y = 24 . (-5) ------> -20x -15y = -120 (A)
6x + 5y = 34 . (3) -------> 18x + 15y = 102 (B)
(A) + (B) ----------> -2x = -18 ---------> x = 9
4.9 + 3y = 24
3y = 24 - 36
3y = -12
y = -4

Price of lunch of each, P = $ 18.45/3 = $ 6.15 .
Now, number of people that can eat the barbecue at a budget of $1850.00 is:
Therefore, Mr. Gaines afford maximum 300 people to feed on a budget of $1850.00 .
Hence, this is the required solution.
3y=6x+12
y = 7 + 3x
y = 3x + 7
y = mx + b, therefore the y-intercept is 7.
3y = 6x + 12
y = 2x + 4
y = mx + b, therefore the y-intercept is 4.

Answer:
Isabel
Step-by-step explanation:
Gavin saves 28% (given).
Harry saves 1 -3/4 = 1/4 = (1/4)·100% = 25%.
Isabel saves 3/(3+7)·100% = 30%.
Isabel saves the largest fraction of her salary each month.

Substitution Method
Answer:
For negative sign , the graph reflects over x -axis and for 1/2 there will be a vertical compression
Step-by-step explanation:
Parent function is f(x)= x
We need to find the effect of the graph when f(x) is replaced with -1/2f(x)
When negative sign is multiplied outside f(x) like -f(x), then there will be a reflection over x-axis
When negative sign is multiplied inside f(x) like f(-x) then there will be a reflection over y-axis
When a number is multiplied outside f(x) then there will be a vertical stretch or compression
Here 1/2 is multiplied outside f(x). is less than 1 so there will be a vertical compression
For negative sign , the graph reflects over x -axis and for 1/2 there will be a vertical compression
