Answer:

y = 1/3x - 3

Step-by-step explanation:

First, find the slope

(3, -2)

(0, -3)

-2-(-3) = 1

3 - 0 = 3

Slope = 1/3

Now, find the y intercept

y = mx + b

-2 = 3 * 1/3 + b

-2 = 1 + b

-3 = b

Rewrite the equation

y = 1/3x - 3

Please let me know if I did something wrong!

I made some brownies and cookies to sell for a local fundraiser. The cookies sold for $0.75 each and the brownies sold for $1.25

juin [17]

Answer:

Brownies made the most money

Step-by-step explanation:

Let c = cookies

b = brownies

We sold 51 items so c+b = 51

Cookies are .75 and brownies are 1.25

.75c + 1.25 b = 53.25

We have 2 equations and 2 unknowns

c = 51-b

Substituting into the second equation

.75(51-b) + 1.25b = 53.25

Distribute

38.25-.75b +1.25b = 53.25

Combine like terms

38.25+.5b = 53.25

Subtract 38.25 from each side

38.25 +.5b -38.25 = 53.25 -38.25

.5b =15

Divide each side by .5

.5b/.5 = 15/.5

b = 30

Now find c

c =51-b

c = 51-30

c = 21

They sold 30 brownies and 21 cookies

30 brownies * 1.25 =37.50

21 cookies *.75 = 15.75

Brownies made the most money

What is the factored form of this polynomial?

oksian1 [2.3K]

Answer:

$(x - 4)(x + 9)$

Answer C is correct.

Step-by-step explanation:

${x}^{2} + 5x - 36 \\ {x}^{2} + 9x - 4x - 36 \\ x(x + 9) - 4(x + 9) \\ = (x - 4)(x + 9)$

hope this helps

brainliest appreciated

good luck! have a nice day!

Number 2 please help

Answer:

you just have to check the first and the third box

Step-by-step explanation:

put each into slop intercept form

y+6=-5(x-2) is the same as y=-5x+4

y-2=-5(x+6) is the same as y=-5x-28

y=-5x+4

y=-5x-28

all of them have a slope of -5, but you need to plug in (2,-6) to see which on is true

The volume of a right circular cone is 300 cubic inches. What is the volume, in cubic inches, of

Jet001 [13]

Answer:

900 cubic inches.

Step-by-step explanation:

Given the following data

Volume of right circular cone = 300in³

We know that the volume of a right circular cone is given by the formula;

$V = \frac{1}{3} \pi r^{2}h$

Where;

V is the volume of right circular cone.

r is the radius of the base of the right circular cone.

h is the height of the right circular cone.

The volume of a right circular cylinder is given by the formula;

$V = \pi r^{2}h$

Thus, multiplying the volume of the right circular cone by 3 would give us the volume of the right circular cylinder.

$V = \frac{1}{3} \pi r^{2}h * 3$

Substituting into the equation, we have;

V = 300 * 3

V = 900in³

Therefore, the volume of a right cylinder that has the same base and height as the cone is 900 cubic inches.
