Y - 4x = 7...y = 4x + 7
now sub 4x + 7 in for y in the other equation
2y + 4x = 2
2(4x + 7) + 4x = 2
8x + 14 + 4x = 2
12x = 2 - 14
12x = - 12
x = -1
y - 4x = 7
y - 4(-1) = 7
y + 4 = 7
y = 7 - 4
y = 3
solution is : (-1,3)
it would be 240 men
Step-by-step explanation:
i took the same test
1. p=7.50+5.50v
p is the total price, v is the amount of visitors
For 6 visitors, it is $40.50
2. p=100+15x
p is the total price, x is the amount of dinner served
For 20 guests, it is $400
3.c=4.25+3.5p
c is the total cost, p is the amount of additional pecks you choose
For 3 pecks, it is $14.75
Answer:
(13,-23)
Step-by-step explanation:
Comparing the image coordinates to the transformation rule, you see that ...
(x -4, y +15) = (9, -8)
Adding (4, -15) to these coordinates, we get ...
(x -4, y +15) +(4, -15) = (9, -8) +(4, -15)
(x-4+4, y+15-15) = (9+4, -8-15)
(x, y) = (13, -23) . . . . coordinates of D
791 since it has no decimal places
