Y 4x Math
So you can make 24 cupcakes not every equation represents a direct variation or a direct proportion.
Y 4x math. You will need to get assistance from your school if you are having problems entering the answers into your online assignment. In this case 4x is another way of saying 4 times x or x x x x. Now we graph those points on an x y coordinate grid. Every ordered pair on the line makes the equation y 4x true.
On the given graph you can find all of the important points for function y 4x if they exist. Y 2x 1 is a linear equation. Y 2x 1. Free math problem solver answers your algebra geometry trigonometry calculus and statistics homework questions with.
It also has commands for splitting fractions into partial fractions combining several fractions into one and cancelling common factors within a fraction. We will help you get there. Examples of equations that are direct variations. Phone support is available monday friday 9 00am 10 00pm et.
When x is 0 y is already 1. Since y varies directly with x y kx find k when x 1 and y 6 6 k 1 6 k therefore y 6x is the direct variation equation when x 4 y 6 4 24. Reach your personal goals for mastering algebra. Straight line slope 8 000 2 000 4 000 x intercept 5 4 1 25000 y intercept 5 1 5 00000 rearrange.
X is an unknown variable. Use the slope intercept form to find the slope and y intercept. Here are some example values. Y 4x y 5x y 4 6 x y.
What are people saying about mathpapa. For example if you were to say. The algebra section allows you to expand factor or simplify virtually any expression you choose. You can master algebra at your own pace and build a strong foundation of math knowledge.
The slope intercept form is where is the slope and is the y intercept. We can connect the dots. Rearrange the equation by subtracting what is. A lack of spacing between symbols indicates multiplication.
When x increases y increases twice as fast so we need 2x. Find the values of and using the form. Tap for more steps. The graph of y 4x represents a graph of a linear function.
Regular practice with our exercises will solidify your algebra skills. If you have questions about the solution feel free to email. So 1 is also needed. Every ordered pair off that line makes the equation false.
