(a) Lying on both axes-  

Point lying on both axes will lie on origin, so its coordinate is (0,0)

(b) Lying on x-axis and with x-coordinates 4

Since the point lies on x-axis so its y-coordinate is 0, so its coordinate is (4,0)

(c) Lying on y-axis and y-coordinates -3

Since the point lies on y-axis so its x-coordinate is 0, so its coordinate is (0,-3)

Just number 4 please hurry and help meeee
Hoochie [10]

Answer:

C D H

Step-by-step explanation:

The best way to tackle this problem is to put each answer into the equation and evaluate the equation.

for example

-(-3.9) + 6 >= 10

3.9 + 6 >= 10

9.9 >= 10 .this is not true!

be very careful with the signs and evaluate each answer.

If 6 pounds of blueberries costs $16.50, is $1 for 2.75 pounds of blueberries true?
strojnjashka [21]

Step-by-step explanation:

Hmm I'm not sure but (no) I think

6 pounds = $16.50

1 pound = $16.50 ÷ 6

=$2.75

$16.50 = 6 pounds

$1 = 6 ÷ $16.50 = 4/11 pounds (0.36363636......)

A regular hexagon is drawn inside of a circle so that each of its vertices touches the circle. the diameter of the circle is 4 c
LenKa [72]
The length of the circumference is (being d the diameter, and using 3.14 for \pi):

L = 2 \cdot r \cdot \pi = d \cdot \pi = 4 \cdot \pi \text{ cm} = 12.56 \text{ cm}

The perimeter of the hexagon is 12 cm.

Hence, the circumference is 0.56 cm longer than the perimeter of the hexagon.
