Answer:

The solution in the attached figure

Step-by-step explanation:

Let

x-----> the number of oranges

y-----> the number of apples

we know that

The inequality that represent this situation is

0.45x+0.25y\leq 2

The solution is the shaded area below the solid line between the positive whole numbers values of x and y

using a graphing tool

Which equation is the slope-intercept form of the line that passes through (6, –11) and is parallel to the graph of y = –23x + 1
Finger [1]

Answer:

Equation of other line passing through point (6 , - 11) and parallel to given line is  y = - 23 x + 127 .

Step-by-step explanation:

Given as :

The equation of one line

y = - 23 x + 12

∵ The equation of line in slope-intercept form is

y = m x + c

where m is the slope of line and c is y-intercept

Now, Compare given line with standard line equation

So, The slope of given line = m = - 23

Now, Again

Other line is passing through point (6 , - 11) and is parallel to given line

so, both the lines are parallel

For parallel line condition , Slope of both lines are equal

Let The slope of other line = M

So, M = m = - 23

Now, Equation of other line passing through point (6 , - 11) and slope - 23 in slope-point form

y - y_1 = M × (x -  x_1)

i.e y - ( - 11) = (- 23) × (x - 6)

Or, y + 11 = - 23 × x + 138

Or, y = - 23 x + 138- 11

i.e y = - 23 x + 127

So, The equation of other line  y = - 23 x + 127

Hence, Equation of other line passing through point (6 , - 11) and parallel to given line is  y = - 23 x + 127 . Answer

how much fence would you need to replace the fence of a 30 foot by 40 foot playground? How much sod would you need to re-sod the
Mrrafil [7]
Perimeter=sum of side lengths...

P=2L+2W

P=2(L+W), in this case L and W are 30 and 40 so

P=2(30+40)

P=2(70)

P=140

So 140 feet of fencing is needed to replace the fence.

The amount of sod needed is equal to the area which is LW

A=30(40)=1200 ft^2
