Step-by-step explanation:

x² + y² + z² = 3(2x - y) - 1

x² + y² + z² = 6x - 3y - 1

x² - 6x + y² + 3y + z² = -1

(x - 3)² + (y + 1.5)² + z² = -12.25

(x - 3)² + (y + 1.5)² + z² = -(3.5)²

Since it follows the general equation form, it is a sphere.

for each x-y table given,copy the table, find the pattern and fill in the missing entries. Then write the rule for the pattern i

mash [69]

Answer:

see the attached for the table and rules

Step-by-step explanation:

a) A graph of the given points shows they lie on the same line, one with a slope of 3 and a y-intercept of 2. Thus the rule is ...

y = 3x +2

see the attachment for table values

b) The ratios of given points are all the same: y/x = 5/2, so that is the constant of proportionality:

y = (5/2)x
