Answer:

Step-by-step explanation:

Yes!

A rational number is one that can be formed by a fraction. Real numbers include them along with the irrational numbers. The only kind of number that is not included is the complex number system - sqrt(-1) is one example.

Rational numbers: 4/5, 22/55, -56/44,3/1

Irrational numbers: still real sqrt(44),

Real numbers: both those listed above.

Graph y = -2 and x= 3 individually state the slope and x and y intercept form for each

attashe74 [19]

y = -2 and x= 3

Graph is attached below. Black line is the graph of y=-2

Blue line is the graph of x=3

Whenever we get equation like x = something, in that case slope is always undefined

Whenever we get equation like y = something, in that case slope is always 0

y = -2 and x= 3

For x=3, the slope is undefined.

The graph of x=3 is a vertical line at 3 on x. The x intercept is 3 and there is no y intercept.

For y=-2, the slope is 0

The graph of y=-2 is a horizontal line at -2 on y. The y intercept is -2 and there is no x intercept.

Find the maximum value of the function for the polygonal convex set determined by the given system of inequalities.

V125BC [204]

Answer:

A. at (8,7) the maximum value is 98

Step-by-step explanation:

First draw the region, that is bounded by all

inequalities. This is the triangle with vertices

(6,1), (2,5) and (8,7).

Now you can see where the line f(x,y)=7x+6y

intersect this region. The maximum value will be

at endpoints of this region:

• at (6,1), f(6,1)=7-6+6-1=42+6=48;

at (2,5), f(2,5)=7·2+6.5=14+30=44;

• at (8,7), f(8,7)=7.8+6-7=56+42=98.

Thus, the maximum value of the function is 98 at

the point (8,7).
