What is the slope of a line perpendicular to the line whose equation is 9x+6y=18

Mathematics

Luba_88 [7]1 year ago
6 0

answer:

slope: -2/3

step-by-step explanation:

y=mx+b

m represents the slope, and b the y-intercept.

rearrange: 9x= -6y+18

---> -6y= -9x-18

divide all terms by -6.

-6y/-6= -9/-6x-18/-6

y= 3/2x+3 (slope/intercept form)

m= 3/2

---> 1/3/2= -2/3

Circular area rugs are priced at $5 per foot based on the circumference of the carpet used. What is the cost of the largest circ
ryzh [129]

Answer: 110

Step-by-step explanation:

We first need to find the maximum perimeter of the circular area rug that will fit in the rectangular space. We use the shortest side of the rectangle as the diameter of the rug.

A circle drawn inside a rectangle.

A rectangle has a length of 12 feet and a height of 7 feet. A circle is drawn inside in the center of the rectangle with a line labeled Diameter extending from the top most point of the circle to the bottom most point of the circle.

P=2πr=2π×72=21.9911 ft

We then multiply the perimeter of the rug by the cost per foot.

cost =21.9911×5=$109.9555

Rounded to the nearest whole number, the cost of the maximum circumference circular rug that can fit in the dining room is 110 dollars.

Vaselesa [24]

Answer:

first is the chart so for the time row its 4, 8, 12, 16, 20 & distance is 3, 6, 9, 12, 15

I added the complete graph down below, basically what i did wasplot the points from the chart so (4,3), (8,6), (12,9), (16, 12), and (20,15)

so for example for (4,3) you would first find 4 on the x-axis or the time line and then find 3 on the y-axis and so on let me know if you can see the picture:)
