Answer:

x=-4

Step-by-step explanation:

X would be -4 because if you distribute 2 to (-3x-4) it would give you (-6x-8) and then collecting like terms you would get (x-8=-12)  then you would add 8 to -12 whih would equal -4.

butalik [34]

Answer:

10 feet

Step-by-step explanation:

  1. Multiply 20 by 6 which will give the answer 120 (in inches).
  2. Then convert 120(inches) to feet by dividing with 12.
  3. The answer will be 10(feet) needed for six shelves.

20x6= 120

120/12=10

=10 ft

stellarik [79]

Answer:

y-intercept is the weight of the animal at birth (when x = 0)

Step-by-step explanation:

y=3.86x+15

The slope (gradient) of the function is 3.86

The y-intercept of the function is 15

Therefore, the y-intercept is the weight of the animal at birth (when x = 0)
