Answer:
x = 1/2 or 0.5
Step-by-step explanation:
3x - 4 = x +5 (1) subtract x
2x - 4 = 5 (2) subtract 5
2x + 1 (3) divide by 2
x = 1/2 or 0.5
Since the sphere is located at the center and has radius 5.
Out of the following given points,
(5,5,-5) will lie on the sphere, where x and y coordinates will be positive and z coordinate will be negative.
This is because the radius of the circle is 5 units.

Answer:
y = -3/2x + 2
Step-by-step explanation:
slope-line equation : y = mx + b
slope is -3/2
Let's find the y-intercept using (6, -7)
y = mx + b
-7 = -3/2(6) + b
-7 = -18/2 + b
-7 = -9 + b
+9 +9
-----------------------
2 = b
So, y = -3/2x + 2 is your equation.
