Answer:

\large\boxed{y+1=2(x-3)}

Step-by-step explanation:

The point-slope form of the equation of a line:

y-y_1=m(x-x_1)

m - slope

(x₁, y₁) - point

We have the slope m = 2 and the point (3, -1). Substitute:

y-(-1)=2(x-3)\\\\y+1=2(x-3)

Answer:

y=2x+(-7)

Step-by-step explanation:

y=2x+c

solve for c

-1=2(3)+c

-1=6+c

-6-1=c

c=-7

<u>y=2x+(-7)</u>

Do i begin with division first?
lara31 [8.8K]
Use PEMDAS. Division comes before addition. start with 9/25 ÷ 18/15. You will divide those like you would normally divide a fraction, so yes, do the inverse of 18/15 and multiply that by 9/25. after you've done that, take that answer and add the 5/8 to it.

Match each verbal description to its equivalent function rule as applied to the given function below.

The top-left graph goes with the bottom-right equation, y=90(1/4)^x

The bottom-left graph goes with the top-right equation, y = 120(3/4)^x

The top-right graph goes with the bottom-left equation, y = 120(1/4)^x

The bottom-right graph goes with the top-left equation, y = 90(3/4)^x

y=90(1/4)^x has a larger percent decrease than y = 90(3/4)^x
cause if you multiply a number by 1/4, that's smaller than multiplying number by 3/4. so y=90(1/4)^x decreases really fast

same with the y = 120(3/4)^x ones

A right come has a slant height of 17 feet, and the diameter of the base is 16 feet. What is the height, h, of the cone?
adelina 88 [10]

Answer:

h = 15 feet

Step-by-step explanation:

A right triangle is formed by the slant height, the radius of the base and h, with the slant height being the hypotenuse.

Using Pythagoras' theorem in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

Since base diameter = 16 then radius = 8

h² + 8² = 17²

h² + 64 = 289 ( subtract 64 from both sides )

h² = 225 ( take the square root of both sides )

h = \sqrt{225} = 15

Help please with my algebra test !!!!
attashe74 [19]

Answer:

Option 4

Step-by-step explanation:

Ok so I don't now how to explain this well but basically, -2 < 4 are both x. The very bottom of the line is shown as -2 and the very top of the is shown as 4. The bottom of the line is increasing to 4. So therefore it would be option 4. Sorry if you don't understand very well.
