Answer:

NO.

Step-by-step explanation:

It is geometric if there is a common ratio between adjacent terms

-6 / -14 = 3/7.

2 / -6 = -1/3

So there is no common ratio.

Not geometric.

Answer:

No it is not.

Step-by-step explanation:

Reason.

For geometric: common ratio r should be equal

r = T2/T1 = T3/T2 but is not true here as -6/-14 is not equal to 2/-6

Greg swam 4 kilometers against the current in the same amount of time it took him to swim 16 kilometers with the current. The ra
ad-work [718]

Answer:

5 kmph

Step-by-step explanation:

Given: Greg swam 4 kilometers against the current.

            Greg swam 16 kilometers with the current.

            Rate of the current was 3kmph.

Lets assume the speed of greg swimming with no current be "x".

∴ Speed of swimming against current= (x-3)\ kmph

   Speed of swimming with current= (x+3)\ kmph

As given, it took same amount of time to swim both with current and against current.

∴ Forming an equation to find the value of x, which is speed of greg swimming with no current.

We know, Time= \frac{Distance}{Speed}

⇒ \frac{4}{(x-3)} = \frac{16}{(x+3)}

Multiplying both side by (x+3) and (x-3)

⇒4\times (x+3)= 16\times (x-3)

Using distributive property of multiplication.

⇒ 4x+12= 16x-48

Subtracting both side by 4x and adding by 48.

⇒60= 12x

Dividing both side by 12

⇒x= \frac{60}{12} = 5\ kmph

Hence, Greg can swim at the rate of 5kmph with no current.

Given the domain {-2,2,4} what is the range for the relation 9x+3y=6
OleMash [197]

Answer:

{8,-4,-10}

Step-by-step explanation:

re arrange relation, im going to assume x is the domain input and y is the range.

-3x+2=y

plug in every element of the set x to get the range set y

-3(-2)+2=y

y=8

-3(2)+2=y

y=-4

-3(4)+2=y

y=-10

so the range is {8,-4,-10}
