2x-3y-4z=-24 has 3 potential intercepts. The x, y and z interceps. To find the x intercept we set y=z=0 This gives 2x=-24 or x=-12 To find the z intercept we set x=y=0 This gives -4z=-24 or z=6 Lastly to find the y intercept, x=z=0 so -3y=-24 and y=8 The x intercept is (-12,0,0), the y intercept is (0,8,0) and the z intercept is (0,0,6)

What does factoring a quadratic allow you to do?
Factoring a quadratic allows you to solve the x and y intercepts. The x-intercepts in the factored form are the inverse of the constants. The y-intercept is the product of the x-intercepts multipied together. Example: x²-10x-24 = (x+2)(x-12) +2 and -12 are the constants. So ur x-intercepts are (-2,0) (12,0). The y intercept is -24 because -2 X 12 = -24.
How do you find measure of minor arc?
the measure of a minor arc equals the measure of the central angle that intercepts it.
Find intercepts of xy equals 4?
There are no intercepts because the curve, xy = 4 is asymptotic. When x = 0 (where the y intercept would be) y is infinite, and conversely, when y = 0 x is infinite.
How many x-intercepts does the graph of y equals x2 have?
Just one. It's at the origin. (0, 0)
What are intercepts for 7x-3y equals 21?
If the equation is 7x - 3y = 21 then (3, 0) and (0, -7).
What are the x and y intercepts of Y equals 2X plus 24?
12
What are the intercepts of the line 4x plus 3y equals 24?
(6, 0) and (0, 8)
What is the x and y intercepts for 2x-3y equals 24?
x-intercept:2x = 24x = 12y-intercept:-3y = 24y = -8
What are the x and y intercepts for the equation 8x-7y equals 168?
Put in function form. 8X - 7Y = 168 - 7Y = - 8X + 168 Y = 8/7X - 24 0 out Y 8/7X - 24 = 0 8/7X = 24 X = 21 ---------- 0 out X Y = - 24 ----------- (21,-24) X and Y intercepts.
What is y equals -x using intercepts?
y = -xBoth intercepts are at the origin. From there, the line slopes up to the leftand down to the right.
Find the slope and intercepts of each line y equals -x plus 1000?
Slope: -1 intercepts: (0,1000),(1000,0)
What are the intercepts of 2x-3y-4z-24?
The question does not contain an equation but an expression. An equation can have intercepts, an expression cannot.
How do you find the intercepts of F of X equals 6000 - 75x?
It is 6000.
What are the x-intercepts and Y-intercepts for the graph 3x plus 15 equals 5y?
X intercept: -5 Y intercept: +3
How many x intercepts does the graph of y equals x2 have?
One. It is a double root.

The y intercept is -24 because -2 X 12 = -24.
Why does y equals 0 when solving a quadratic equation?
Because when your solving a quadratic equation your looking for x-intercepts which is where why equals 0 and x equals what ever the answer is.
