Guys PLZZZ help mess

Answer to 1. 2. 3.

Step-by-step explanation:

1. Pairs of socks: 1, 4, 5, 10

Cost in dollers: 2.50, 10, 12.50, 25

you can buy 10 pairs of socks for 25$

2. Miles: 35, 280, 420

Gallons: 1, 8, 12

Mr. fink cand drive 280 miles on 8 gallons of gas.

3. Pages 1, 2, 3, 4, 5, 6

Stickers: 9, 18, 27, 36, 45, 54

Jenny has 54 stickers in her unicorn sticker book.

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3

the answer is 31.27mph
