What is gf 4 if f x equals 5x and g x equals 3x - 7?
f(x)=5x, g(x)=3x-7 gf(x)= = g(f(x)) = g(5x) = 3*(5x) - 7 = 15x-7 So gf(4) = 15*4-7=53
Which point is on the graph of 5x-2y equals 4?
When y=4, x=8/5
How do you graph 5x 10 equals 20?
5x - 10 = 20Add 10 to each side:5x = 30Divide each side by 5:x = 6If you feel that you must graph this equation for some reason,then your graph is a vertical line, parallel to the y-axis, passingthrough the point [ x=6 ] on the x-axis.
How do you graph g of x equals x-6?
g(x) = x-6 is the function g(x) = x with a negative vertical shift of 6. That is to say, take the whole graph of g(x) = x and move it down 6 units.
What are the x-intercepts of the graph of y equals 12x2 - 5x - 2?
Using the quadratic equation formula: x = -1/4 and x = 2/3
If y equals 5x - 2 were changed to y equals x - 2 how would the graph of the new function compare with the first one?
The graphs of y = 5x - 2 and y = x - 2 will have different slopes but with the same y intercepts.
What is y equals x 5x equals 12y?
5x=11y
How do you graph 5x-6y equals -30?
5x -6y=-30 5x-6y=30 (2x+3y) (2x-3y)=30 4x+6y=30 4x=30 x=30/4
What is 5x-x equals 48?
-43
if f(x)=4x-8 and g(x)=5x+6 find (f+g)(x) if?
(f+g)(x) = 4x + 8 + 5x -6 => (f+g)(x) = 9x + 2
How do you graph and shade x plus y equals 8 x equals 6 5x plus 2y equals 20?
To graph them, you need to put them into the formula y=mx+b. If x+y=8 subtract x to get y=-x+8. 8 is the y-intercept and your line should be heading downward from left to right.
4x - 7 equals 5x - 2 what does x equals?
4x-7=5x-2 x=-5
