7. Logan saved $35 from cutting the neighbor's yard. He earns $10 a week from washing dishes, which he also saves. Which function can be used to find s, the amount of money Logan will have saved at the end of w, weeks of washing dishes? A. s=10w+35
B. s=45
C. s=35-10w
D. s=35w+10

i think it’s A but i’m not sure

Step-by-step explanation:

since you have to multiply 10 by how many weeks he washed the dishes & if you get it wrong i’m sorry

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

(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
