Write a linear function with the values f(6)=8 and f(9)=3*PLEASE HELP IM SO LOST*

Answer:

y = -5x/3 + 18

Step-by-step explanation:

The points can be written as;

(x,f(x))

where f(x) is same as y

So the points we have are;

(6,8) and (9,3)

We start by finding the slope or the line connecting the points

m = y2-y1/x2-x1 = (3-8)/(9-6) = -5/3

So now we have the general form of a linear equation as

y = mx + b

where m is slope and b is y intercept

We already have slope and we want to calculate y-intercept

Simply substitute one of the points

(9,3) in this case

9 for x and 3 for y

we have ;

y = -5x/3 + c

3 = -15 + c

c = 18

So the line equation is;

y = -5x/3 + 18

\sqrt{-4} can also be written as 2i 
where i = √-1

\frac{2i}{4-2-3i} =  \frac{2i}{2-3i}

Rationalizing denominator,

\frac{2i(2+3i)}{(2-3i)(2+3i)} =  \frac{4i-6}{4+9} =  \frac{4i-6}{13}

What is the simple interest earned on $3,672 at 4.5% for three years?
olasank [31]

Answer: interest at the end of 3 years is $495.72

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time in years

I = interest after t years

From the information given

T = 3 years

P = $3,672

R = 4.5%

Therefore

I = (3672 × 4.5 × 3)/100

I = 49572/100

I = 495.72

The first term of an arithmetic sequence is 7 and the sixth term is 22. Find(a)the common difference;(2)(b)the twelfth term;(2)(
SVEN [57.7K]

d = 3 , a₁₂ = 40 and Sx_{100} = 7775

In an arithmetic sequence the nth term and sum to n terms are

<h3>• an = a₁ + (n-1)d</h3><h3>• S_n = \frac{n}{2}[2a + (n-1)d]</h3><h3>where d is the common difference</h3><h3>a₆ = a₁ + 5d = 22 ⇒ 7 + 5d = 22 ⇒ 5d = 15 ⇔ d = 3</h3><h3>a₁₂ = 7 + 11d = 7 +( 11× 3) = 7 + 33 = 40</h3><h3>S₁₀₀ = \frac{50}{2}[(2×7) +(99×3)</h3><h3>       = 25(14 + 297) = 25(311)= 7775</h3>
