Given definitions, or descriptions at least, of "point D" and "the feasible region",
I might have had a shot at answering this one.
(6x)(5y)
The x-intercept is the point where the y-intercept is zero. "3x 5y 9" is not an equation. 3x+5y+9, or 3x-5y+9, are examples of what was meant to be shown.
5y+8=7y 2y=8 y=4
If y = 10 then (5*10)-25 = 25
Presumably you want to know the value of y. 3y+2y+4+1 = 80 5y+5 = 80 5y = 80-5 5y = 75 y = 15
The answer depends on the feasible region and there is no information on which to determine that.
(6x)(5y)
Since there is no feasible region defined, there is no answer possible.
It is 18.
The answer obviously depends on what the boundaries of the feasibility region are.
The question cannot be answered because:there is no symbol shown between 3x and 5y,there is no information on the feasible region.The question cannot be answered because:there is no symbol shown between 3x and 5y,there is no information on the feasible region.The question cannot be answered because:there is no symbol shown between 3x and 5y,there is no information on the feasible region.The question cannot be answered because:there is no symbol shown between 3x and 5y,there is no information on the feasible region.

If: 4x = 5y Then: x = 5y/4
f(-2,3) = 11 f(5,-3) = -5 f(1,4) = 22, maximum
5y+8=7y subtract 5y from each side , 5y+8=7y -5y -5y 8=2y /2 /2 4=y
-3 Solution Method: ------------------ 1. Clarify the problem: What is the y-intercept of 6x-5y=15? 2. Recall what the "y-intercept" is: "the y-intercept is the y coordinate when the x value = 0 or the b value in the slope-intercept form (y = mx + b (b=the y-intercept value)) of the point-slope equation (y - y1 = m(x-x1). 3. Input the x coordinate into the equation & find the y value: 6(0)-5y=15 0-5y=15 -1/5 * -5y = 15 * -1/5 y = - 3 (this is your y-intercept value) OR when (y = mx + b), then b = the y-intercept value) 6x - 5y = 15 -6x - 5y = -6x + 15 -5y = -6x + 15 -1/5 * 5y = (-6x + 15) * -1/5 y = 6/5x - 3 (-3 = the y-intercept value) ================ A2. I am assuming you mean 6x - 5y = 15. Since the y intercept is at x=0, plugging x=0 into the equation gives 6(0)-5y=15. Since 6(0)=0, this gives -5y=15. Dividing both sides by -5 gives y=-3. Remember, the y-intercept is a point, so, since x=0, the point is (0,-3). A1?: ---------------------- Another way ---------------------- The equation is 6x - 5y = 15 The equation for graphing a line is y = mx + b where b is the y-intercept. Try to get it in this form - 6x - 5y = 15 (Add 5y on both sides) 6x = 15 + 5y (Subtract 15 from both sides) 6x - 15 = 5y (Since we need to get a single y, divide both sides by 5) (6x)/5 - (15)/5 = (5y)/5 (Simplify) 6/5x - 3 = y Therefore, the slope is 6/5 and the y intercept is -3. Good luck!
