Answer:
Linear
The function is linear since the graph of it would be a straight line. You can tell this by looking at the equation since there are no squares, roots, division, etc. that would make the line stray.
Answer:
(x + 6)² + (y - 2)² = 75
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (- 6, 2) and r = 5
, hence
(x - (- 6))² + (y - 2)² = (5 )², that is
(x + 6)² + (y - 2)² = 75
Answers
six weeks. divide 13.5 miles of road needing repairs by the rate of 2.25 miles of road per week to obtain 6 weeks. If you are not familiar with converting fractions to decimals and using a calculator, multiply 2 by 13 and add 1 to obtain the stretch of road needing repairs as 27/2 miles and the road repair rate as 2 times 4 plus 1 divided by 4 = 9/4 miles per week divide 27/2 miles by 9/4 miles per week to obtain 6 weeks [ 27/2 times 4/9 ]
