X = -4y+3
-x-4y = -3
________________
x+4y = 3
-x-4y = -3
0 = 0
Possible and determined system (single solution)
y = mx + b, where m = slope, and b = y-intercept.
Since you are not given the y-intercept, you have to solve for it through the equation, y = (4/5)x (which is the slope you are given) + b, and replace x and y with values given, which are (-5,-3)
y = (4/5)x + b
-3 = (4/5)(-5) + b
-3 = -4 + b
1 = b
Then replace b in the first equation to get the answer
y = (4/5)x + 1
First write it in vertex form :-
y= a(x - 2)^2 + 3 where a is some constant.
We can find the value of a by substituting the point (0.0) into the equation:-
0 = a((-2)^2 + 3
4a = -3
a = -3/4
so our equation becomes y = (-3/4)(x - 2)^2 + 3

Answer:
M = 2x² - (ax/3) + by
B = - 3x²y + (xy³/3) - cy
Step-by-step explanation:
Equation 1 is
2x² - (1/3)ax + by - M = 0
M = 2x² - (ax/3) + by
Equation 2
3x²y - (1/3)xy³ + cy + B = 0
B = - 3x²y + (xy³/3) - cy
Hope this Helps!!!
