Taila earns d dollars per week. How much does Taila earn in 10 weeks?
Andreas93 [3]

Answer:

10d dollars

Step-by-step explanation:

d is a variable, which is just a placeholder for an unknown value. Therefore, we can treat d as if it's a number.

If you earn a certain amount of dollars per week, and you work for 10 weeks, then to find how much money you earn, you'd multiply the amount of weeks (10) by the dollars per week right?

Same logic applies for variables.

Since we have d acting as a placeholder for the amount earned per week, then the total amount of money earned in 10 weeks is 10\cdot d, which can just be represented as 10d.

Hope this helped!

Determine the intercepts of the line
TiliK225 [7]

Answer:

x-int: (-40, 0)

y-int: (0, 15)

General Formulas and Concepts:

<u>Algebra I</u>

  • The x-intercept is the x value when y = 0.  Another way to reword that is when the graph crosses the x-axis.
  • The y-intercept is the y value when x = 0.  Another way to reword that is when the graph crosses the y-axis.

Step-by-step explanation:

According to the line on the graph, it passes the x-axis at x = -40 and it passes the y-axis at y = 15.

Therefore, our x-int is (-40, 0) and our y-int is (0, 15)
