Answer:
x = 90 / 3
Step-by-step explanation:
Given : 3 candies cost 90 cents
Given this we want to determine the cost of 1 candy.
To find the cost of "something" given the cost of multiple quantities of that "something" we simply divide the total price by the # of products.
Here the total price is 90 cents and the # of products is 3 ( 3 candies )
This means that the cost of 1 candy ( x ) would be = to 90 / 3
Answer:
f(x) is the total cost and x is the number of peaches.
We know that each peach costs $0.75. This means the expression 0.75x represents the total cost of peaches; this makes x represent the number of peaches.
We also know that $2.25 is the cost of juice. Adding it to the cost of peaches gives us the total cost; this means f(x) represents the total cost.
Answer:
- gradient is 4.
- y-intercept is -5.
- No.
Step-by-step explanation:
1. In order to find the gradient of equation, you have to make it into slope-form equation y = mx + b :
So m represents gradient. In this question, m is 4.
2. Make it into slope-form equation :
In this question, y-intercept is b which is -5.
3. You have to substitute x-coodinate into the equation to see whether it is equal to y-coordinate :
