Answer:
y =
Step-by-step explanation:
Standard equation in point slope form is :
y-y_0 = m(x-x_0) +c
where m = slope = -1/2
(x_0,y_0) is the point from which the lines passes through = (5,-3)
We get the equation as,
y-(-3) = -1/2(x-5)
y+3 = (x-5)
y =
y =
Hence, m= -1/2 and c = -1/2
Required equations is:
y =
Let
x-------> the first number
y-------> the second number
P-----> product
we know that
x+2y=56----------> 2y=56-x-----> y=28-0.5x------> equation 1
P=x*y----> equation 2
substitute equation 1 in equation 2
P=x*[28-0.5x]-----> P=28x-0.5x²
using a graph tool
see the attached figure
the vertex is the point (28,392)
that means
for x=28
the product is 392 (maximum)
find the value of y
y=28-0.5x----> y=28-0.5*28----> y=14
the answer is
the numbers are 28 and 14
