Answer:
y = 3x
Step-by-step explanation:
The exact equation for the climb would be y = (x-3)^2 + 9, however, a rough line that represents the climb is y = 3x.
Find the slope between (0, 0) and (3, 9) and we get m = 3. Plug it into y-int form and you get the line.
They give us the length of side of the square which is 3-7x.
To get an expression for the perimeter that is expressed as a product we have to multiply the expression 3-7x by four since every square has four sides. This will give us an expression of 4(3-7x). We than can use the distributive property to multiply everything inside the parenthesis by 4. This will give us an expression of 12-28x.
Answer:
15 + 3n
Triple the amount of evening which is “n” so it would “3n”
The morning amount would still be 15
The formula for the cost of the total sales is: 8a+5c where a is the number of adult tickets and c is the number of child tickers.
If he keeps 15% the formula is: 0.15(<span>8a+5c) </span>
Answer:
We first must solve for x
When we have x, we put it in to the second equation
