Answer:
Step-by-step explanation:
The equation y = 5x - 2 is slope-intercept form of linear function.
- The shape of the graph is the line
It has positive slope of 5, therefore is increasing function, the line goes up from left to right on the coordinate plane
Answer:
Use the equation h(t)=-b/2a to find the x value of the vertex, then plug that back into the equation to find the y value which is your height.
Step-by-step explanation:
You can also complete the square to get the equation into vertex form, then your height is the y value of your vertex. Remember the maximum height is always at the vertex of an inverted parabola.
Answer: f(x) is just a fancy way of writing y in an equation
Step-by-step explanation:
Example: f(x)= 2x+4 is the same as y= 2x+4
Answer:
y = 4/5x - 9/5
Step-by-step explanation:
4x - 5y = 9 to solve for y you get it by itself.
-4x -4x minus 4x from both sides
-5y = - 4x + 9
/-5 /-5 Divide both sides by 5
y = 4/5x - 9/5 because -4/-5 is 4/5 and 9/-5 is - 9/5
Answer:
For example, 8f + 4g is one of the most used expression
Another example is 4 (2f + g), is correct too
