4s - 3
9r - 17
3r + 13
7s
Solve for s

Step-by-step explanation:

step 1. the diagram is very unclear and should be redone

step 2. I'll assume 9r - 17 and 3r + 13 are vertical angles and are equal

step 3. 9r - 17 = 3r + 13

step 4. 6r = 30 or r = 5

step 5. I'll assume 4s - 3 and 7s - 24 are alternate interior angles and are equal

step 6. 4s - 3 = 7s - 24

step 7. 3s = 21 or s = 7.

(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

it would more likely be bald eagle because its has more in the box so about 75%.
