Well by looking at the graph I can see that the equation for the line is y=-0.5x-4
rearranging I can get the answer.
y>=-0.5x-4
y+0.5x>=-4
2y+x>=-8



the answer is
2x+4y>=-16

<h3>Answer: 2x+4y ≥ -16 </h3>

Step-by-step explanation:  In the given graph x-intercept is -8 and y-intercept is -4.

Also the graph is shaded up of the line for greater values of y's.

On the option 2x+4y ≥ -16 has x-intercept at -8 and y-intercept at -4.

Also all other inequalities has only less than or greater than sign.

In the given graph we have a solid line.

So, there should be greater than or equal to inequality sign for the inequality.

Only option 4 has greater than with equal to sign.

Therefore, correct option is 2x+4y ≥ -16

Anne wants to fill 12 hanging baskets with compost. Each hanging basket is a hemisphere of diameter 40 cm.
murzikaleks [220]

Answer:

no

Step-by-step explanation:

Steps to answering this question

  1. determine the volume of the 12 basket

volume of a hemisphere = (2/3)πr^3

n = 22/7

r = radius

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

radius = 40/2 = 20 cm

volume of one hemisphere = (2/3) x (22/7) x (20^3) = 16,761.90 cm^3

volume of the 12 baskets = 16,761.90 cm^3 x 12 = 201,142.86 cm^

2. convert the litres of compost to cm and multiply by the total bags of compost

1 litre = 1000cm

1 bag of compost = 50 x 1000 = 50,000

4 bags of compost = 50,000 x 4 = 200,000 cm

3. compare which figure is higher. the figure gotten in step 1 or 2

201,142.86 cm^3 is greater than 200,000

there is no enough compost

What is the Gcf of the number below
never [62]

9514 1404 393

Answer:

  b.  60

Step-by-step explanation:

The list of factors is 2, 3, 5, 7. The list of common factors is 2, 3, 5. The lowest exponents on those factor are ...

  2^2 × 3^1 × 5^1 = 60

The GCF of 720 and 2100 is 60.

_____

<em>Additional comment</em>

You can verify this using Euclid's method of finding the GCF.

  2100/720 = 2 r 660

  720/660 = 1 r 60

  660/60 = 11 r 0 . . . . 60 is the GCF

Find the remainder from the division. If it is zero, the divisor is the GCF. If it is non-zero, replace the largest number with the remainder, and repeat.

Solve for x. Show your work.
puteri [66]
So, these are actually pretty simple once you learn the equality used to solve for "x" and when to implement this method. You can use this equality to solve for a segment "x" anytime that two secant lines cutting through a circle come from the same point outside the circle. 

Secant: by geometric definition is just a straight line that cuts a curve into multiple pieces.

I did one of them for you hopefully you can use my work for "a" to help you solve for "b".  For a. I got x=7.

8,699 rounded to the nearest ten
aleksley [76]
Ok so first You look at the number:8,699. Where's the Tens place?  The tens place is easy to find by using expanded notation......8,000 + 600 + 90 + 9.
90 is the tens place you see? So in order to answer this right,You keep Every number on the right side of 90 and add it to 90 So.......90+9 = 99 .

99 is the area you going to round. In order to round you look at the one place
(the 9) and and see if its a number bigger than the number 5 which it is!
so read this.........4 or below let it go,5 or above give it a shove.  So because it bigger than 5 you round it up. so.......8,6(99) rounded up would be simple.....

99 goes up so 90 (the tens place) goes to 100.  BUT 8,6100 is wrong and you should now that so just do this.

99 turned to 100 so 600 (Hundreds place)  + 100 (tens place rounded) = 700
