Answer:
it would be 4
Step-by-step explanation:
I’m pretty sure the answer is E. X is a linear function. Z is a cubed root function. W is a quadratic function and Y is exponential
Answer:
see explanation
Step-by-step explanation:
x + y = 90 → (1) ( complementary angles )
x + z = 180 → (2) ( supplementary angles ) and
z = 3x - 8 ( 8 less than 3 times x ), substituting in (2)
x + 3x - 8 = 180
4x - 8 = 180 ( add 8 to both sides )
4x = 188 ( divide both sides by 4 )
x = 47
Substitute x = 47 into (1)
47 + y = 90 ( subtract 47 from both sides )
y = 43
and z = 3x - 8 = 3(47) - 8 = 141 - 8 = 133
Thus
x = 47°, y = 43° and z = 133°
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
8 and 24 let me know if this helps
