Using this model, what would be the cost of a flight that travels 1375 miles? Round your answer to the nearest dollar.

C) $143.

Step-by-step explanation:

We are given an equation: y = 0.0714x + 44.8.

x is the number of miles, and y is the cost.

y = 0.0714 * 1,375 + 44.8

y = 98.175 + 44.8

y = 142.975

So, the cost is about C) $143.

Hope this helps!

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
