(1,5)
Step-by-step explanation:
Simultaneous equations
4x+3y=19
4x=19-3y
x=(19-3y)/4___put in the other equation
7(19-3y)/4-6y=-23
Solving gives y=5 and x=1
The missing angle would be 68 because the the triangles can be alternate exterior
Answer:
9s+11
Step-by-step explanation:
Combine like terms → (7s+2s and 2+9 = 9s and 11) and boom
Additive relationships mean you add the SAME number to any x-value to get the corresponding y-value. If it's not the same number every time, it is NOT an additive relationship. Subtraction can be an additive relationship because subtracting a number is the same as adding a negative number (example: 5 - 2 = 5 + (-2)).
