Answer:
Step-by-step explanation:
Quadrilateral ABCD is inscribed in a circle. So, ABCD is a cyclic Quadrilateral.
Opposite angles of cyclic quadrilateral are supplementary.
Therefore,
Answer:
x = -2, y = 7
Step-by-step explanation:
Since it's a system of equations, we know that the they use the same variables. To use substitution to solve a system of equation, we must take one equation and solve it for a variable, then you plug the solution into that variable for the other equation:
-2x + y = 11
y = 2x + 11
-------
4x + 4y = 20
4x + 4(2x + 11) = 20
4x + 8x + 44 = 20
12x + 44 = 20
12x = -24
x = -2
Then we can plug "x" into the first equation:
-2x + y = 11
-2(-2) + y = 11
4 + y = 11
y = 7
Answer:
y = (-3/4)x + 2
Step-by-step explanation:
y = m * x + b where m is the slope and b is the y-intercept
y = (-3/4)x + b substituting the slope
4 = 6 + b => b = 2 substituting the point given
y = (-3/4)x + 2
Answer:
y = - 4x + 20 ... slope=-4 y intercept:20
Step-by-step explanation:
2y+8x=20
2y=-8x+20
y = - 4x + 20 ... slope=-4 y intercept:20
(y = mx + b)
Are you asking me to demonstrate how to handle that equation ?
Are you expecting to get the procedure and solution here ?
If you were asking a question, would that be it ?
Well, OK. You manipulated me into it.
5p + 2 = 4p - 1
Subtract 4p from each side: p + 2 = - 1
Subtract 2 from each side: p = - 3
