If f(n) = 3n+ 5 , find f(-3). soln, 3n+ 5​

Step-by-step explanation:

Using the power law of indices:

When two numbers with the same base multiply,add the exponents that is

[tex] {a}^{2} \times {a}^{3} = {a}^{2 + 3} = {a}^{5} [/tex]

Again,when two numbers with the same base divide, subtract the exponents,that is

[tex] {a}^{2} \div {a}^{4 } = {a}^{2 - 4} = {a}^{ - 2} [/tex]

There are way too many examples that is why I have elaborated the two laws for your perusal.

So for instance:

1.

[tex] {2}^{2} \times {2}^{5} = {2}^{7} [/tex]

Answer:

2² × 2⁵ = 2⁷

            = 128

4⁴ × 4⁶ = 4¹⁰

           = 1048576

6² × 6⁷ = 6⁹

           = 10077696

9⁸ × 9⁸ = 9¹⁷

           = 1.6677182e+16

Do try the rest out yourself!!! You can do it!!!

Answer:

3/4 of the ribbon is needed to make a bow

Step-by-step explanation:

12 ÷ 4 = 3

so out of that foot of ribbon you use 3/4 of it for the bow

Answer:

3 times

Step-by-step explanation:

Equation: 810 = 288x

x = 2.8 meaning you need to fill up the tank 3 times

Answer:

4

Step-by-step explanation:

We can find the slope using the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 3 - -1)/( 7-6)

    = ( 3+1)/( 7-6)

    = 4/1

   =4

Answer: bn= 150*3^(n-1)( bn is a quantity of bacteria in generation n)

Step-by-step explanation:

It looks like geometrical sequence, each next generation is three times greater than previous one. So the r of this sequence is 3.

The first generation has 150 representatives, so b1=150

The formula of geometrical sequence is bn=b1*r^(n-1)

(in our case bn is a quantity of bacteria in generation n)

so bn= 150*3^(n-1)( bn is a quantity of bacteria in generation n)

Answer:

A. y ≤ 1

Step-by-step explanation:

according to the graph, the coordinates of maximum value is (-3, 1) and besides the graph towards down, so, the range of the function is y ≤ 1

Answer:

3x + 40

Step-by-step explanation:

"More" means addition and "Triple" indicates multiplication.

So, 3x + 40 is the answer.

Answer:

Here,

X=(1,4,7,9)

Y=(2,4,5,9)

Now,

i=(1,2,4,5,7,9)

ii=((4,9)

iii=(1,2,4,5,7,9)

iv=(4,9)

Answer:

the answer is c

Step-by-step explanation:

x - 7, y + 6

- 1 - 7, 4 + 6

- 8, 10

Hey there! I'm happy to help!

In this case c is equal to 0. There is always a, b, and c, but they might be invisible (for example if a is 1 or b or c are 0).

Then you can choose whichever method you like to factor these (completing the square, quadratic formula, factoring, etc.)

The zeros should be 0 and a number that is about -1.9.

Have a wonderful day and keep on learning! :D

Answer:

6

Step-by-step explanation:

-9+6=-3

Answer:

Step-by-step explanation:

remember this:-

if +,- comes: change sign to - (eg. 8+(-4)= 8-4=4)

if -,+ comes: change sign to - (eg. 8-(+4)= 8-4=4)

if -,- comes: change sign to + (eg. 8-(-4)=8+4=12)

if +,+ comes: change sign to + (eg. 8+(+4)=8+4=12)

16

Step-by-step explanation:

5/8= 0.625

10/0.625= 16

Answer:

P/2 -w = l

Step-by-step explanation:

P = 2l + 2w

Subtract 2w from each side

P-2w = 2l + 2w-2w

P -2w = 2l

Divide each side by 2

(P-2w)/2 = 2l/2

P/2 -w = l

Answer:

1

Step-by-step explanation:

In the equation -7 - (-8), there are two 'minus' signs; we can convert two minus signs into a plus sign according to the 'minus minus equals plus' rule, that would make the equation (-7) + 8 for which the answer is +1.

Answer:

1

Step-by-step explanation:

-7-(-8)

therefore;

  -7-(-8)= -7+8

therefore;

   -7+8= 1

Hope you understand.If you have any problem just ask me I will solve it.

Answer: 1/4n-12=6

1n/4-12=6

n=72

Step-by-step explanation:

Answer:

72

Step-by-step explanation:

let the number be n , then

[tex]\frac{1}{4}[/tex] n - 12 = 6 ( multiply through by 4 to eliminate the fraction )

n - 48 = 24 ( add 48 to both sides )

n = 72
