Answer:

m=Y2–Y1/X2–X1

$m = \frac{ - 9 - (6)}{1 - ( - 4)} \\ m = \frac{ - 15}{5} = - 3 \\ y = mx + b \\ y = - 3x + b$

Answer: y = -5x - 14

Step-by-step explanation:

first find the difference between the x variables x1 = 1 and x2=-4 to find the slope(m)

-4 - 1 = -5

next find the difference between the y variables to find b

-9 - 6 = -14

Kevin cycles 18 miles every morning as part of his exercise. The time it takes him to complete the distance varies inversely as

Lelechka [254]

Answer:

The $T = \frac{18}{m}$ best models the amount of time it takes him to finish with kelvin cycling .

Option (A) is correct.

Step-by-step explanation:

As given

Kevin cycles 18 miles every morning as part of his exercise.

The time it takes him to complete the distance varies inversely as the speed at which he rides.

$Time \propto \frac{1}{Speed}$

$Time = \frac{Distance}{Speed}$

As m miles per hour is represented the speed.

T is the time taken by Kevin cycle for morning exercise .

Distance = 18

Putting the values in the above

$T = \frac{18}{m}$

Therefore the $T = \frac{18}{m}$ best models the amount of time it takes him to finish with kelvin cycling .

Option (A) is correct.

Answer:

483.56 square milimeters

Step-by-step explanation:

In the above question, we obtain the following information:

Slant height = 15mm

Radius = 7mm

π = 3.14

Since we are given the slant height ,

the formula for surface area of a cone = πrl + πr²

= πr (l + r)

= 3.14 × 7(15 + 7)

= 3.14 × 7( 22)

= 21.98(22)

= 483.56 square milimeters

A pair of shoes cost $22.99 to make, the local store sells them for $36.99. What is the percent markup? (Round to the nearest hu

ASHA 777 [7]

C: 60.9% is the right answer

Step-by-step explanation:

The markup is calculated by using the formula

$Mark\ up=Selling\ price-make\ price$

Given

Make Price = $22.99

Selling Price = $36.99

So the mark up will be:

$Mark\ up=36.99-22.99\\=\$14$

Percent mark up will be:

$Mark\ up=\frac{Mark\ up}{Make\ price}*100\\=\frac{14}{22.99}*100\\=0.6089*100\\=60.89\%$

Rounding off to the nearest hundredth percent

60.9%

Hence,

C: 60.9% is the right answer
