Answer: y=x+5
Step-by-step explanation:
So the dots are going at a slope of 1 up and 1 right each time, so your slope would be 1, or simply x if you times it. To line it up with the slope, you have to move up 5 on your y-axis, known as your b. Then from there, you go up 1 over 1 which will line up with all the dots.
Step-by-step explanation:
a1 = 5500, since you are starting there, and n would represent the level you want to complete. 3250 would be d, or the number you are going up by each time.
This would give you the equation an = 5500 + 3250(n-1) as the explicit formula, and an = an-1 + 3250 as your recursive formula.
Answer: Restaurant: $34.50; Toy Company: $4.50
Step-by-step explanation:
Let's represent the situation mathematically. I will use "r" for the restaurant stock price and "t" for the toy company stock price.
represents the value of their stock portfolio.
represents that the restaurant stock was worth $30 more than the toy company stock.
We need to multiply the second equation by 60 to balance the terms out. This gets us .
Now, you can combine the like terms in these equations to get , which can be simplified further to .
Now you need to divide both sides by 102 to remove the coefficient, getting you . This means that the price of the restaurant stock was $34.50.
To find the toy company stock price, subtract $30 from the restaurant stock price, because the restaurant stock is worth $30 more than the toy company stock. This gets you $4.50.
