Answer:

no solution

Step-by-step explanation:

both sides = -2 when we substitute n for 2 so

therefore it doesn’t have solution or doesn’t satisfy the inequality

Cuz n should be > not equal

The coordinates below represent two linear equations.

Hello,
Answer A: no solution

line 1: (-6,3), (3,6)==>y-3=(x+6)*3/9==>x-3y=-15 (1)
line 2: (-3,1), (3,3)==>y-1=(x+3)2/6==> x-3y=-6 (2)

(1)-(2)==>0x=-9 ==> no solution
line 1 // line 2

V=2.5(6.4−t)

Alja [10]

Answer:

6.4 minutes ( or 6 minutes and 24 seconds)

Step-by-step explanation:

Filling up the jug means the empty space is 0, hence V = 0.

<em>We plug in 0 into V and solve for t to get the time required to fill it up:</em>

$V=2.5(6.4-t)\\0=2.5(6.4-t)\\0=16-2.5t\\2.5t=16\\t=\frac{16}{2.5}\\t=6.4$

Hence it will take 6.4 minutes to fill up the jugs.

<u>Note:</u> 0.4 minutes in seconds is $0.4*60=24$ seconds

What is the measure of an exterior angle of a regular 7-sided polygon? The answer must be a decimal.

ale4655 [162]

1 interior angle = [(n-2)180]÷n
= [(7-2)×180]÷7
= 900÷7 = 128.57 °
an exterior angle = 180 - interior
= 180-128.57
= 51.43°

Select all of the functions that have a constant rate of change

jonny [76]

Hi,

The request actually is to choose functions whose derivative is a constant.

For A, derivative is $\dfrac{1}{2\sqrt x}$ , which is not constant.

For B, derivative is 2ˣ·ln2, which is not constant.

For C, derivative is 0, which is a constant.

For D, derivative is 1, which is a constant.

So, you can choose C and D.

Have you understood ?

Green eyes.
