Answer:

No, not really.

dividing 25 into 4 equal groups, equals 6.25.

So no, you can not divide 25 into 4 equal group.

If if was 25 into 5 equal groups, then yes.

Hope this helps!!!

Please mark brainliest, if this helps. :)

\log_4(x+10)-\log_4(x-2)=\log_4(x)\implies \log_4\left( \cfrac{x+10}{x-2} \right)=\log_4(x) \\\\\\ \stackrel{\textit{exponentializing both sides}}{4^{\log_4\left( \frac{x+10}{x-2} \right)}=4^{\log_4(x)}}\implies \cfrac{x+10}{x-2}=x\implies x+10=x^2-2x \\\\\\ 10=x^2-3x\implies 0=x^2-3x-10 \\\\\\ 0=(x-5)(x+2)\implies x= \begin{cases} 5~~\checkmark\\ -2 \end{cases}

notice, -2 is a valid value for the quadratic, however, the argument value for a logarithm can never 0 or less, it has to be always greater than 0, so for the logarithmic expression with (x-2), using x = -2 will give us a negative value, so -2 is no dice.

The first rule is to add 10, then divide by 2 starting from 2. The second rule is to multiply by 3, then subtract 2 starting fro
julsineya [31]

Answer: (2, 2), (6, 4), (8, 10), (9, 28)

Step-by-step explanation:

The first four ordered pairs using the two sequences are:(2, 2), (6, 4), (8, 10), (9, 28)

The first rule is to add 10, then divide by 2 starting from 2

Add/Divide:

10=2+10=12

2=12÷2=6

Add/divide again:

10=6+10=16

2 = 20÷2 = 10 2=16÷2=8

Add/divide again:

10=8+10=18

2=18÷2=9

Describe the transformations of : f(x)=x^2 to g(x)=3(x+5)^2+2<br><br> Help!!!
Shalnov [3]

Answer:

see explanation

Step-by-step explanation:

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then a shift to the left of a units

• If a < 0 then a shift to the right of a units

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a vertical shift up of c units

• If c < 0 then a vertical shift down of c units

Given

g(x) = (x + 5)² + 2

This represents a shift to the left of 5 units and a shift up of 2 units
