Answer:

Step-by-step explanation:

Given the inequality x ≤ 2

Since the inequality includes an equal then x can equal 2

This is denoted by a solid circle on 2 on the number line

Since the inequality is less than 2 then the arrow points to the left.

Thus the third line is the required graph → C

Divide R300 000 between Leona and Janet in the ratio 3:2.

ella [17]

Answer:

let the ratio be in x 

a/q. 3x + 2x = 300000

 5x = 300000

x = 300000/5

x= 60000

Leona = 60000*3 = 180000

Janet = 60000*2 = 120000

hope it helps

Plz answer all corectly will mark brainlest plz answer within 1 hour

denis23 [38]

Answer:

for the first one I got y=-2x-2 the second part i got y=-x-1 or -1x-y-1=0 Correct me if I am wrong

Step-by-step explanation:

Use the slope formula

-4-4 =-8

/ =-2

1 - -3=4

2. The second part use this formula y-y1=m(x-x1)

y--4=-1(x-3)

y+4=-x+3

-4 -4

y+0=-x-1

y=-x-1 or -1x-y-1=0 I am not sure

The yield of orange trees is reduced if they are planted too close together. If there are 30 trees per acre, each tree produces

Tanya [424]

Answer:

5 more than 30 trees should be planted, for a total of 40 trees per acre.

Step-by-step explanation:

Let x be the number of trees beyond 30 that are planted on the acre

The number of oranges produced = Oranges(x) = (number of trees) (yield per tree)

We are given that For each additional tree in the acre, the yield is reduced by 7 oranges per tree

So, number of oranges produced = $(30 + x)(400 -10x)$

= $12000 -300x+400x-10x^2$

= $12000 + 100x-10x^2$

The derivative Oranges'(x) = 100-20x

Substitute first derivative equals to 0

$100-20x =0$

$x=5$

Using the second derivative test,

Oranges"(x) = -20

20 is negative,

So, this is the case of maximum.

Thus, 5 more than 30 trees should be planted, for a total of 40 trees per acre.
