Answer:
Step-by-step explanation:
y - 1 = 2(x + 2)
y - 1 = 2x + 4
y = 2x + 5
Triangles have common side AC, and 2 adjacent to this side corresponding angles.
∠BAC=∠DCA, and
∠ACB=∠SAD.
So, triangles <span>ABC and ADC are congruent by ASA.</span>
Answer:
the slope is 1
Step-by-step explanation:
9514 1404 393
Answer:
y = 2
Step-by-step explanation:
The variable x can be eliminated by subtracting the first equation from the second.
(-x +4y) -(-x -y) = (15) -(5)
5y = 10 . . . . . . . simplify
y = 2 . . . . . . . . . divide by 5
The answer is 10 because it all goes up by 10
