6 0

1. 4x – 20 = 5y

so 5y = 4x – 20

divide both sides by 5

y = (4/5)x - 4

2. x-intercept is at y=0

so (4/5)x - 4 = 0

x = 5

so it is (5,0)

3. y-intercept is at x=0, y = 0 - 4 = -4

so it is (0,-4)

What is the answer to this

arlik [135]

$S\frac{O}{H} C\frac{A}{H} T\frac{O}{A}$ or $Sin\frac{Opposite}{Hypotenuse}Cos\frac{Adjacent}{Hypotenuse} Tan\frac{Opposite}{Adjacent}$

At the point/angle E:

- the adjacent side(side next to the point/angle) is ED

- the opposite side(side of the triangle across from the point/angle) is DF

- the hypotenuse (the longest side of the triangle) is EF.

sin ∠E = $\frac{opposite}{hypotenuse}$

sin ∠E = $\frac{6}{10} = \frac{3}{5}$ (simplified)

Maria is draining her hot tub at a rate of 5.5 gallons per minute. Is the amount of water left in the pool a function of the amo

AleksandrR [38]

The amount of water in the pool after t minutes is modeled by the linear function $V(t) = V(0) - 5t$ , hence it is a function of time.

A linear function for the amount of water in the pool, considering that it is drained at a rate of a gallons per minute, is modeled by:

$V(t) = V(0) - at$

In which V(0) is the initial volume.

In this problem, draining her hot tub at a rate of 5.5 gallons per minute, hence $a = 5.5$ , and:

$V(t) = V(0) = 5.5t$

Which is a function of time.

The shortest side of an isosceles triangle is 2x - 3 inches long. the longer sides are 6 inches longer than the shortest side. t

Zolol [24]

Side 1 = short side = 2x-3
side 2 = longer side = (short side) + 6 = (2x-3)+6 = 2x+3
side 3 = side 2 = 2x+3

Side 2 and side 3 are the longer two congruent sides

Add up the three sides and set them equal to the given perimeter of 33. Solve for x

(side1)+(side2)+(side3) = perimeter
(2x-3)+(2x+3)+(2x+3) = 33
(2x+2x+2x) + (-3+3+3) = 33
6x+3 = 33
6x+3-3 = 33-3
6x = 30
6x/6 = 30/6
x = 5

If x = 5, then the longer sides are 2*x+3 = 2*5+3 = 10+3 = 13 inches each
(note: the short side is 2*x-3=2*5-3=10-3 = 7 inches)

Answer: 13 inches
