Answer:
B
Step-by-step explanation:
the question says -12x ≤ -72.the sign ≤ means less than or equal to. so we will divide both sides by -12 to get the value of x. and that wil give us x ≤ 6, the sign did not change because we used a sign common to both sides to divide it. that is slso the reason why we had a positive value.
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
Proceed the inverse. Swap the x and y.
So the answer is first one.
A rational number is that number that can be expressed as a ratio between two integers. Thus integers are also rational numbers: ex: 7=7/1=14/2, 5=-5/(-1)=5/1=15/3,....
Examples of rational numbers: 1/5, 2/3, -5/7, etc
