1 answer:
SCORPION-xisa [38]3 years ago
3 0

Answer:

y = -5x + 5

Step-by-step explanation:

Let the equation of the line be: y = ax + b.

The given points should satisfy the equation.

Substituting the points in the equation we get the values of 'a' and 'b'.

The first point is: (1,0)

⇒ 0 = a(1) + b ⇒ 0 = a + b

⇒ b = -a

(2, -5) is another point. Substituting this we have:

-5 = a(2) + b = 2a - a = a

⇒ a = -5

⇒ b = -a = 5.

Therefore, the equation of the line becomes y = -5x + 5.

Which expression can be used to find the surface area of the following square pyramid?
telo118 [61]

Answer:

Step-by-step explanation:

The slant height of one side of this pyramid is 5, and the base of this side is 4.  Thus, the area of one slant side is (1/2)(5)(4) = 10 units^2.

There are 4 such sides.  Thus, the total slant surface area is 4(10 units^2), or 40 units^2.  

If you also want to include the base area, the total would be

40 units^2 + 16 units^2 = 56 units^2.

How far from an airport can an airplane fly and return in 8 hours, if it's outgoing speed is 160 km per hour and it's returning
PilotLPTM [1.2K]
<span>speed = distance/time
total time is 8 hours

outgoing speed is 160 km per hour, 
so time = d/160

</span><span>returning speed is 240 km per hour,
so time = d/240

 d/160 + d/240 = 8

3d/480 + 2d/480 = 8
5d/480 = 8
5d =480 (8)
5d = 3840
d=3840/5
d=768

answer: so the distance is 768 km</span>
