Answer:

The answer is option (C)=an-1+7

Step-by-step explanation:

A recursive rule is a formula that in which each term is expressed as a function of its preceding term(s), meaning in order to get to the nth term you have to express it in a form of the term that comes before it. In our case the a(n-1) term

So for the sequence -9, -2, 5, 12

The nth term is any number on the sequence and

  • -2 is the a(n-1) term for -9
  • 5 is the a(n-1) term for -2
  • 12 is the a(n-1) term for 5

So we need to find out what we have to do to the preceding term to get the next.

To get -2 from -9 we have to add 7 to -9; -9+7=-2

To get 5 from -2 we have to add 7 to -2; -2+7=5

To get 12 from 5 we add 7 to 5; 7+5=12

So the recursive rule would be= a n-1+7

Blizzard [7]

Answer:

Approximately what will be saved will be 8.00

Step-by-step explanation:

Here, we want to know the amount that the customer will save

Firstly, we need to know the amount that all will cost

Mathematically, that will be;

24 + 16.12 + 10.5 = 50.62

The amount to be discounted is 15% of this

That will be 15% of 50.62

= 15/100 * 50.62

= 7.593

[No links please and explain it out.♡︎]
Sholpan [36]

Answer:

y = mx+b

m represents the slope and b represents the y-intercept

since you have the slope and a point you can find here the line crosses the y-axis

y = -1/2x + b

the point (-14, 6) can be substituted into the eq for x and y

(6) = -1/2(-14)+b

6 = 7 +b     (subtract 7 from both sides)

-1 = b

The line crosses the y-axis at -1

What is the simplified version of 3\sqrt{135}
Aleonysh [2.5K]

Answer:

The simplified version of \sqrt[3]{135} is 3\sqrt[3]{5}.

Step-by-step explanation:

The given expression is

\sqrt[3]{135}

According to the property of radical expression.

\sqrt[n]{x}=(x)^{\frac{1}{n}}

Using this property we get

\sqrt[3]{135}=(135)^{\frac{1}{3}}

\sqrt[3]{135}=(27\times 5)^{\frac{1}{3}}

\sqrt[3]{135}=(3^3\times 5)^{\frac{1}{3}}

\sqrt[3]{135}=(3^3)^{\frac{1}{3}}\times (5)^{\frac{1}{3}}      [\because (ab)^x=a^xb^x]

\sqrt[3]{135}=3\times \sqrt[3]{5}     [\because \sqrt[n]{x}=(x)^{\frac{1}{n}}]

\sqrt[3]{135}=3\sqrt[3]{5}

Therefore the simplified version of \sqrt[3]{135} is 3\sqrt[3]{5}.
