Answer:
66 degrees
Step-by-step explanation:
angle M=angle P
so:
15x-18=13x-8
reducing:
2x=10
x=5
angles M & P each are 57 degrees
180-57-57=angle L
66 degrees
Answer:
-x2 + 2x + 8
Step-by-step explanation:
Your first step will be to set up the problem:
f(x) - g(x)
Next, you will substitute in your values:
(2x + 1) - (x2 - 7)
The easiest way to do the subtraction problems is to distribute your negative into your second set of parenthesis, so your expression would become:
2x + 1 - x2 + 7
Then combine your like terms:
2x - x2 + 8
Lastly, put your expression in standard form (highest exponent to lowest)
-x2 + 2x + 8

Step-by-step explanation:
{7,16,24} cannot form a triangle
Answer:
Part 1)
Part 2)
Part 3) The coordinates of endpoint C are (13,5)
Step-by-step explanation:
Part 1) The endpoints of line RS are R(1, -3) and S(4,2). Find RS
we now that
the formula to calculate the distance between two points is equal to
substitute the values
Part 2) The endpoints of line CD are C(-8,-1) and D(2,4). Find CD
we now that
the formula to calculate the distance between two points is equal to
substitute the values
Part 3) The midpoint of line AC is M(5,6). One endpoint is A(-3,7). Find the coordinates of endpoint C
The formula to calculate the midpoint between two points is equal to
Let
(x2,y2)-------> the coordinates of point C
(x1,y1) -------> the coordinates of point A
substitute the given values
write the equations
therefore
The coordinates of endpoint C are (13,5)
