2. 5 times w increased by 4 is 2 times u .



3. z is 6 more than twice y.



4. 2.5 more than quotient of a and 4 is b .


Write a function rule representing each situation.
1. The price p of a pizza is $4.95 plus $0.5 for each topping t on the pizza.



2. The cost c of the membership of a club is $30 for sign up and $15 per week w to be a member.



3. The cost d of a hotdog is $1 more than half the cost of a sandwich s.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
