Answer:

Step-by-step explanation:

Simply plug each x value into the equation

1.

-3, 0, 3, 6, 8, yes it is linear, it doesn't have any exponents

2.

Same thing

5,2,1,2,5, it has exponenets and is not linear

Answer:

$5,175

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

I = 4500 × 0.05 × 3 = 675

I = $ 675.00

The simple interest accumulated

on a principal of $ 4,500.00

at a rate of 5% per year

for 3 years is $ 675.00.

Answer:

12a + 24 = 6(2a + 4)

Step-by-step explanation:

Given the numbers :

4, 12a 6 2a and 24 ; create an equivalent expression :

12a, 2a, 4, 6, 24

We could separate tbe constant terms and those with variables :

12a, 2a ; 6, 4, 24

We could put the larger digit to one side

12a + 24 = 6(2a + 4)

This way the Right hand side is equal to the left hand side.

Check:

12a + 24 = 6(2a + 4)

12a + 24 = 12a + 24

Hence, the proof

Step-by-step explanation:

Your question isn't well written but let me help out by making some assumptions.

Let's say Jamie's older brother and his three friends want to split the cost of lunch that costs $30 and they also want to leave a 20% tip. How much should each person pay?

Cost of the lunch = $30

Tip = 20% × $30 = 0.2 × $30 = $6

Total amount to be paid = $30 + $6 = $36

Since there are four people and they want to share the cost, each person would pay:

= $36 / 4

= $9

Answer:

OB

because domain is all X values that satisfy graph. And on graph X has all +ve values going to infinity.

When the Function g is defined as g(x) = 2f(x – 4) + 3 so the domain of the function g is OB. {x|0 < x <♾}.

Since the Function g is defined as g(x) = 2f(x – 4) + 3

So here OB should be considered as the domain of the all x values should satisfied the graph. Also, on graph X it contains the positive values that goes to infinity.

Hence, When the Function g is defined as g(x) = 2f(x – 4) + 3 so the domain of the function g is OB. {x|0 < x <♾}.

If it said negative exponent then x root -1, -2 etc etc.

Answer:

Step-by-step explanation:

When writing negative exponents as positive exponents, you move the base (the number being exponentiated) to the denominator and the exponent becomes positive.

Answer:

one jumbo cost $4 and one chocolate cost $2

Step-by-step explanation:

Let the price eif one jumbo be x

Let the price of one chocolate be y

If one jumbo and 2 chocolate cost$6, then

x+2y= 6 ... 1

If one jumbo and 4chocolate cost $8, then;

x +4y = 8... 2

Subtract both equations

2y -4y = 6-8

-2y= -2

y = 1

Substitute y = 1 into 1;

From 1, x+2y = 6

x +2(1) = 6

x = 6-2

x = 4

Hence one jumbo cost $4 and one chocolate cost $2

Answer and Step-by-step explanation:

Given the system of equations:

2x – 5y = 13

–3x + 2y = 13

We can decide to eliminate either x or y in order to solve the simultaneous equations.

1. To eliminate x:

Multiply the first equation by the coefficient of x in the second equation and multiply the second equation by the coefficient of x in the first equation. By doing this the coefficients of x in the equations would be the same and subtracting them to be equal to zero becomes easy, thus eliminating that variable.

The coefficient of x in the second equation is –3, if we multiply the first equation by it we have:

–6x+15y = –39

The coefficient of x in the first equation is 2, if we multiply the second equation by it we have:

–6x+4y = 26

Subtracting the resulting equations we have:

11y = –65 and x is eliminated.

2. To eliminate y:

Multiply the first equation by the coefficient of y in the second equation and multiply the second equation by the coefficient of y in the first equation. By doing this the coefficients of y in the equations would be the same and subtracting them to be equal to zero becomes easy, thus eliminating that variable.

The coefficient of y in the second equation is 2, if we multiply the first equation by it we have:

4x–10y = 26

The coefficient of y in the first equation is –5, if we multiply the second equation by it we have:

15x–10y = –65

Subtracting the resulting equations we have:

–11x = 91 and y is eliminated.

Answer:

The number of branches triples every 15 years.

Step-by-step explanation:

Satoshi started studying how the number of branches on his tree grows over time.

The relationship between the elapsed time t, in years, since Satoshi started studying the tree, and the number of its branches, N(t), is modeled by the following function:

N(t) = 24 - 3^t/15

Complete the following sentence about the growth rate of the branches. The number of branches triples every years.

The number of branches triples every 15 years.

Given is that the relationship between the elapsed time [t], in years, since Satoshi started studying the tree, and the number of its branches [N(t)], is modeled by the following function → N(t) = 24 - 3^t/15

The function that models the situation is -

N(t) = 24 - 3ⁿ/15    .... Eq[1]

After tripling the number of branches, we can write -

3N(t) = 24 - 3ⁿ/15

N(t) = {24 - 3ⁿ/15}/3     ..... Eq [2]

Equating both equations, we get -

{24 - 3ⁿ/15} = {24 - 3ⁿ/15}/3

3{24 - 3ⁿ/15} = {24 - 3ⁿ/15}

72 - 3ⁿ/5 = 24 - 3ⁿ/15

72 - 24 = 3ⁿ/5 - 3ⁿ/15

48 = 3ⁿ(1/5 - 1/15)

n = 15

Therefore, the number of branches triples every 15 years.

Answer:

1.625²

Step-by-step explanation!

1.625 x 1.625 is just 1.625 two times. So you add a 2 on the top which represents the number. You can write 1.625² instead of putting 1.625 x 1.625.  

1.625 x 1.625 can be written in exponential form as [tex]1.625^2[/tex]

Given :

The given expression is 1.625 x 1.625 . we need to write it in exponential form

The exponent is in the form of [tex]b^x[/tex], where 'b' is the base and 'x' is the exponent

base is the number and x is the exponent that is repeating number of times

For example , [tex]2 \cdot 2 \cdot 2 = 2^3[/tex]

where 2 is the base and 2 is occurring three times

so exponent is 3

1.625 x 1.625 can be written in exponential form as [tex]1.625^2[/tex]
