Answer:
is that even the full answer because I don't know if that is
Answer:
The answer is y=x-5
Step-by-step explanation:
y=x-5
Answer:

Step-by-step explanation:
{у = 3х - 12
{4х + 6у = −6
4x + 6[3x - 12] = −6
4x + 18x - 72 = −6
−6 = −72 + 22x
+72 + 72
___________
66 = 22x
__ ___
22 22
[Plug this back into both equations above to get the y-coordinate of −3];

Answer:
1. (3, 5)
2. (1/2, 4)
Step-by-step explanation:
To find the coordinates of the midpoint of a segment, find the average of the x-coordinates of the endpoints and the average of the y-coordinates of the endpoints.
1. (1, 2) and (5, 8)
x-coordinate of midpoint = (1 + 5)/2 = 6/2 = 3
y-coordinate of midpoint = (2 + 8)/2 = 10/2 = 5
Midpoint: (3, 5)
2. (0, 1) and (1, 7)
x-coordinate of midpoint = (0 + 1)/2 = 1/2
y-coordinate of midpoint = (1 + 7)/2 = 8/2 = 4
Midpoint: (1/2, 4)
Answer:
Step-by-step explanation:
total money = $2.25 = 225 cents
types of denomination in coins or cents are dimes and nickels
dime = 10 cents , nickel = 5 cents
twice of dimes to nickels
let no of dimes = x and no of nickels = y
our equation
10x + 5y = 225
x = 2y
10(2y) + 5y = 225
20y +5y = 225
25 y = 225
y=9
x =2y 2x9 = 18
so the number of dimes = 18 and nickels = 9
cross verification:
10x18 + 5x9 = 180 +45 = 225
