Answer:
y-coordinate is 5 or -1.
Step-by-step explanation:
Point A is at (x, 2) and B is at (x+6, 2). Since AB must lie on the line y=2 and be 6 units long. Point C is on the line x = -3 . So let C be at (-3, y).
Since ΔABC is a right angle, then point C must have the same x-coordinate as point A. Therefore, A(-3, 2) and B(2, 2).
The area of ΔABC is 6. So,
9 = 1/2 (b)(h)
where b is the base and h is the height.
so b = 6 and h = AC
Solving this for C gives
9 = 1/2 (6)(AC)
18/6 = AC
3 = AC
9 = 1/2 (6)(AC)
18/6 = AC
3 = AC
Point C must lie 3 units above point A or 3 units below the point A. If it lies 3 units above, then it has a y-coordinate of 2 + 3 = 5.
If it lies 3 units below, it has a y-coordinate 2 - 3 = -1.
Therefore, y-coordinate is 5 or -1.
Step-by-step explanation:
Combine like terms: (9x-6)+(8x+9)
9x+8x=17x
-6+9=3
(9x-6)+(8x+9)=17x+3
Answer:
the number 9
Step-by-step explanation:
it is never being changed unlike the other terms because they are being directly multiplied by the variable x. but no matter what 9 stays the same.
The equation is 329-34 and then you check if you sibtract right by adding 34 by the nimber you got when you subtract if it gives you 329 you are right
3x +4 >17
3x > 13
13/3
x is at least 4
