The original price of a plane ticket was reduced by $150. if p=the ticket’s original price in dollars, which algebraic expressio

mariarad [96]

Answer:

Reduced price = $ ( p - 150)

Step-by-step explanation:

Let the original price of plane ticket be $p

Price reduced in plane ticket = $150

So the amount actually need to pay for a plane ticket will be given by:

Actual reduced price of plane ticket = $p - $150

i.e Algebraic expression for reduced price is:

Reduced price = $ (p - 150)

PLZ HELP ME. WILL GIVE BRAINLIEST. THANKYOU!!

____ [38]

Answer:

x = 6

Step-by-step explanation:

Given

3x + 30 + x = 10 + 2x + 5x + 2 , simplify both sides

4x + 30 = 7x + 12 ( subtract 7x from both sides )

- 3x + 30 = 12 ( subtract 30 from both sides )

- 3x = - 18 ( divide both sides by - 3 )

x = 6

H(y)=-3y^2+5<br> p(y)=y^3-7y<br> Find (h-p)(y)

gladu [14]

$(h-p))(y) = -y^3-3y^2+7y+5$

Step-by-step explanation:

Given

$h(y) = -3y^2+5\\p(y) = y^3-7y$

We have to find the difference of two functions given

So,

$(h-p)(y) = h(y) - p(y)\\= (-3y^2+5)-(y^3-7y)\\=-3y^2+5-y^3+7y\\=-y^3-3y^2+7y+5$

Hence,

$(h-p))(y) = -y^3-3y^2+7y+5$
