Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
3x + 2y = 26
y = x + 3
Plug in the equation for y
3x + 2(x + 3) = 26
Multiply the 2 with what is in the parantheses
3x + 2x + 6 = 26
Combine like terms and solve for x
5x + 6 = 26
5x = 20
x = 4
Answer:
B(7,9)
Step-by-step explanation:
Let the coordinates of B be (a,b).
The midpoint rule is given by:
We substitute the coordinates of A(2,3), B(a,b) and the coordinates of M are (4.5,6).
Equate the corresponding components.
and
and
and
and
Therefore B has coordinates (7,9)
