What is the equation of the line that passes through the point<br> (5,-2) and has a slope of 6/5
LenKa [72]

Answer:

y = \frac{6x}{5} - 8

Step-by-step explanation:

given slope m = \frac{6}{5}

point (5, -2) for (x1, y1)

equation for point slope form

y - y1 = m(x- x1)

y - (-2) = \frac{6}{5} (x -5)

y + 2 = \frac{6}{5}x - 6, simplify

y = \frac{6x}{5} - 8,

further you can multiply by 5 to get rid of fraction

5y = 6x - 40

Connie keeps her sports card collection in a 54-page book. Each page has 9 slots for cards.
vesna_86 [32]

Answer:

324 slots.

Step-by-step explanation:

If there is 9 slots per page, and 18 pages in the 54 page book are taken up by football cards, that leaves you with 36 pages left. Again, 9 slots per page, so you multiply 9 x 36 and get 324 slots available for baseball cards.

A plane at an altitude of 7000 feet is flying in the direction of an island. If the angle of elevation is 21 degrees from the pl
sleet_krkn [62]

Answer:

6,535.06 feet

Step-by-step explanation:

The set up is right angles

hypotenuse = 7000feet

angle of elevation = 21 degrees

Required

horizontal distance (adjacent)

Using SOH, CAH TOA trig identity

cos theta = adj/hyp

cos 21 =  adj/7000

adj = 7000 cos 21

adj = 7000(0.9336)

adj =  6,535.06

Hence the HORIZONTAL distance until the plane flies over the island is 6,535.06 feet
