Answer:

2x^2-2x-24

Step-by-step explanation:

(x+3)*(2x-8)=2x^2-8x+6x-24

=2x^2-2x-24 (divide by 2)

=x^2-x-12

A tropical punch recipe calls for 300 ml of sugar for every 222 flavor packages. Write an equation that shows the relationship b

mihalych1998 [28]

Answer:

s = 150f

Step-by-step explanation:

A tropical punch recipe calls for 300 ml of sugar for every 2 flavor packages. Write an equation that shows the relationship between s, the amount of sugar in milliliters, and f, the number of flavor packages for this recipe.

The amount of sugar in milliliters = s

The amount of flavor packages for these recipe = f

The relationship between 2 variables

= y ∝ x

y = kx

k = constant of proportionality

Hence:

s ∝ f

s = kf

Note ,

s = 300

f = 2

300 = 2k

k = 300/2

k = 150

Therefore, the equation that shows the relationship between s, the amount of sugar in milliliters, and f, the number of flavor packages for this recipe is:

s = kf

s = 150f

X-intercept = 3, y-intercept = 2

Katen [24]

Answer:

Step-by-step explanation:

(3, 0) (0, 2)

(2-0)/(0-3) = 2/-3= -2/3

y - 0 = -2/3(x - 3)

y = -2/3x + 2

Could someone please help me with this question

bogdanovich [222]

Answer:

10 units

Step-by-step explanation:

Area of a triangle is $\frac{h*b}{2}$ = Area

where h is the height, and b is the base

We can substitute these values into the area equation and get:

$\frac{x*10}{2} = 50$

Multiply both sides by 2:

x * 10 = 100

Divide both sides by 10:

x = 10

The missing side is 10 units long

Consider the following events for a driver selected at random from a general population.

adoni [48]

Answer:

a. P(AnB)

b. P(B|A)

c. $P(A^I|B)$

d. P(A or B)

e. $P(B^I or A)$

Step-by-step explanation:

Since A= driver is under 25 years old (1)

B = driver has received a speeding ticket (2)

a.The probability the driver is under 25 years old and has recieved a speeding ticket.

this simple means the intersection of both set, which can be written as

P(AnB)

b. The probability a driver who is under 25 years old has received a speeding ticket.

This is a conditional probability, probability that B will occur given that A as occur.

P(B|A)

c. the probability a driver who has received a speeding ticket is 25 years or older.

$P(A^I|B)$

d. The probability the driver is under 25 years old or has received a speeding ticket.

P(A or B)

e. The probability the driver is under 25 years old or has not received a speeding ticket.

$P(B^I or A)$

Selena walks from home to school each morning and back home each afternoon.altogether , she walks 2/3 mile each day . How far do

Ivanshal [37]

One days trip of to school from home and back home from school is 2/3 of a mile. We want to know how far it is to school from her house.

To solve this, we simply need to take half of the total distance (2/3)

$\frac{2}{3} / 2$

Next, we need to turn the 2 into a fraction. Every whole number can be made into a fraction by putting it over 1.

$\frac{2}{3} / \frac{2}{1}$

Because we are dividing, we need to invert the second fraction and then multiply.

$\frac{2}{3} * \frac {1}{2}$

Next, we multiply the top of the first fraction by the top of the second and the bottom of the first fraction by the bottom of the second.

$\frac{2}{6}$

Once you reduce, you get:

$\frac{1}{3}$
