a. you would need to know how many toppings are going on the pizza. the price changes depending on the number of toppings, because each one adds 35 cents.
b. x equals the number of toppings. the number of toppings will change from pizza to pizza, so you put a variable in its place so you can use the same equation for every pizza.
c. 12 + 0.35x this is because the base price of every pizza is $12, then you add the number of toppings (x) multiplied by the price per topping ($0.35).
d. 12 + 0.35x when x=3 is 12 + 0.35(3) = 12 + 1.05 = $13.05
Answer:
1 - Avenue A is perpendicular to South St.
2 - 70°
Step-by-step explanation:
1 - North, Center, and South St. are parallel lines. Therefore Ave A will be perpendicular to the three lines.
2 - Ave B and Center street forms a 70° angle. Since Center and South St. are parallel lines, they have corresponding angles. Therefore, Ave B and South St also form a 70° angle. The same is true for Ave B and North St.
4x ( 2x^3-x^2-18x+15)=
4(2)x^(1+3)-4x^(1+2)-4(18)x^(1+1)+4(15)x=
8x^4-4x^3-72x^2+60x
The slope would be B) 0.05
