What is the slope and y-intercept for the graph of the equation Y= 4/5 x - 3 ?

So,

The slope-intercept form is as follows:
y = mx + b

"m" is the slope, and "b" is the y-intercept.  The y-intercept for this equation is (0,b).

Our equation is y= \frac{4}{5} x-3

That means that \frac{4}{5} is the slope, and -3 is the y-intercept.

Answer:

4 x 2 x 10 = 80

Step-by-step explanation:

80 Crackers total divided evenly among the two boxes gives you 40 crackers per box. Next there are 4 packages and 40 crackers in the packages total. So divide 40 by 4. This gives you 10. 10 crackers per package.

What is the slope of the line whose equation is 4x – 6y = 12?
zhannawk [14.2K]
4x - 6y = 12...in y = mx + b form, the slope will be in the m position. So lets turn this equation into y = mx + b form.

4x - 6y = 12....subtract 4x from both sides
-6y = -4x + 12...now divide both sides by -6
y = (-4/-6)x + 12/-6
y = 2/3x - 2...y = mx + b.....slope(m) = 2/3 <==

A rectangular garden 200 square feet in area is to be fenced o against rabbits. Find thedimensions that will require the least a
Rudiy27

Answer:

20 ft by 10ft

Step-by-step explanation:

Area of the garden =200 square feet

Let the dimensions of the garden be x and y

Area, xy=200

x=\frac{200}{y}

Since one side is already protected by a barn,

Perimeter of the garden=2x+y

P(y)=\frac{2X200}{y}+y

P(y)=\frac{400}{y}+y

P(y)=\frac{400+y^2}{y}

The minimum point of P(y) is the point where its derivative equals zero.

P^{1}(y)=\frac{y^2-400}{y^2}

\frac{y^2-400}{y^2}=0

y^2-400=0

y^2=400

y=20feet

Recall:

xy=200

20x=200

x=10feet

The dimensions of the garden that will require minimum fencing is 20 ft by 10ft
