Mathematics

MakcuM [25]3 years ago
3 0

Answer:

if f(x) = ax + b then f-1(x) = (x - b)/a

Step-by-step explanation:

Now

f(x)=ax + b

then y = ax + b

interchanging x and y , we get

or, x = ay + b

or, x - b = ay

or, (x - b)/a = y

therefore,f-1(x) = (x - b)/a

Find the equation of the graphed line.
Tanzania [10]

Answer:

d. y = -⁷/6x - 7

Step-by-step explanation:

✔️First, find the slope (m) using two points on the line, (-6, 0) and (0, -7):

Slope (m) = change in y/change in x

Slope (m) = (-7 - 0)/(0 - (-6))

Slope (m) = -7/6

✔️Determine the y-intercept (b):

The line intercepts the y-axis at -7. Therefore,

b = -7.

✅To write the equation, substitute m = -⁷/6 and b = -7 into y = mx + b

Thus:

y = -⁷/6x + (-7)

y = -⁷/6x - 7

A series is defined by 5+9+13+17+.......+805 a. Find the number of terms of the series. b. Find the sum of the first 20 terms.​
puteri [66]

Answer: the number of terms of the series is 201 numbers

              the sum of the first 20 terms is 890    

the number of terms of the series is \frac{805-5}{4}+1=201

the series have:

u1 = 5

d = 4

=> u(n) = 5 + 4.(n - 1)

=> u(20) = 5 + 19.4 = 81

so the sum of the first 20 terms is (81 + 5).20/2 = 890

( u1 is the first number of the series, d is the  distance between front and rear numbers, u(n) is the overall term of the sequence, u(20) is the 20th of the series)
