Answer:
the substitution method is one way to solve linear equation. the substitution method is when substitute the one y value with the other:
example :
x+y=10
y=10-x ( value of y)
2x+y=12 ( substitute the value of y in the equation )
2x+(10-x)=12
2x+10-x=12 ( now solve for x)
x=12-10
x=2 ( substitute the value of x in the equation x+y=10)
x+y=10
2+y=10
y=10-2
y=8

Answer: Joey is faster
Step-by-step explanation: Because in 1 hour Joey is run 4 mile but in 1 hour Chandler is run 2 mile
The area of a square is its side length squared. So the side length of the square squared is 42, so the side length of the square is sqrt(42). The perimeter of the square is 4 times the side length, or 4sqrt(42), which is approximately 25.92.
Answer: Congruent Angles
Step-by-step explanation:
y - y1 = m(x - x1)
Plug in:
Slope = m = 4
Point = (x1,y1) ----> (-3,7)
y - 7 = 4(x - -3) //Solve for y
y - 7 = 4(x + 3) //Answer
y - 7 = 4x + 12
y = 4x + 12 + 7
y = 4x + 19
Answer: B
