Look at the picture.
We have the right triangle x, y and r. From the Pythagorean theorem we have:
We have the point
Substitute:
Answer:
(4,0)
Step-by-step explanation:
4x+2y=16
-4y+x=4
Multiply the first equation by 2
2(4x+2y)=16*2
8x +4y = 32
Add the 2nd equation
8x +4y = 32
x -4y =4
--------------------
9x =36
Divide each side by 9
9x/9 = 36/9
x=4
Now solve for y
-4y +x =4
-4y +4 = 4
Subtract 4 from each side
-4y +4-4=4-4
-4y =0
Divide by -4
-4y/-4 =0/-4
y=0
(4,0)
Answer:
Step-by-step explanation:
okay so you can take any two points 1 x one y in the form (x, y) and (x, y) so
(2, 5) and (4, 1)
then use the slope formula y2-y1/ x2 -x1
1-5+=4
4-2=2
slope equals 4/2 simplified equals 2
I THINKKKKK!
Answer:
The last one is the answer; The slope of AB is different than the slope of BC.
Step-by-step explanation:
6x−12+2x=3+8x−15
Simplify:
6x+−12+2x=3+8x+−15
(6x+2x)+(−12)=(8x)+(3+−15)(Combine Like Terms)
8x+−12=8x+−12
8x−12=8x−12
Subtract 8x from both sides.
8x−12−8x=8x−12−8x
−12=−12
Add 12 to both sides.
−12+12=−12+12
0=0
The real numbers are the only solution we can have.
