Answer:

Andrew has been in the book club for 18 months.

Step-by-step explanation:

The number of books already read by Andrew = 13 books

He reads 1 book each month after joining the book club.

Number of books he has read after joining the club = 31 books

Number of books read after joining the Club

=  Total books Read  - Books read beforehand

=  31 books   -  13 books

= 18 books

So, the number of books Andrew read within the club = 18 books

Now, as Andrew read 1 book per month

⇒ Andrew reads 18 books in   18 x ( 1 Month)  = 18 Months

Hence,  Andrew has been in the book club for 18 months.

Want does the y- intercept mean ?
mariarad [96]
The y-intercept is the y value  of an equation on  a graph or cordinate grid For example y=mx+b, b would be the y-intercept. Another example, y=2x-2, -2 would be the y-intercept and you would place a point on -2 and go up 2 right 1 because of the slope 2. I hope this helps you to better understand the y-intercept.

If f(x) = 4x – 3 and g(x) = 8x + 2, find each function value
vladimir1956 [14]

Answer:

f[g(3)] = 100

g[f(5)] = 138

g{f[g(-4)]} = -982

Step-by-step explanation:

f(x) = 4x - 3

g(x) = 8x + 2

a. f[g(3)]

First find g(3) by putting x = 3 in g(x) function

g(3) = 8(3) + 2 = 24 +2 = 26

now put this g(3) = 26 as x in f(x)

f(g(3)) = f(26) = 4(26) - 4 = 104 - 4 = 100

b. g[f(5)]

First lets find f(5)

f(x) = 4x - 3

put x = 5 above

f(5) = 4(5) - 3 = 20 - 3 = 17

put this f(5) = 17 as x in g(x)

g(f(5)) = g(17) = 8(17) + 2 = 138

c.g{f[g(-4)]}

First lets solve the inner most function

g(-4) = 8(-4) +2 = -30

put g(-4) = -30 in f(x) to find f(g(-4))

f(g(-4)) = f(-30) = 4(-30) - 3 = -123

put f(g(-4)) = -123  as x in g(x) to find our complete result

g{f[g(-4)]} = g(-123) = 8(-123) + 2 = -982

I really need help plzzz​
Setler79 [48]

Answer:

The answer is y=40x because where the line hits a center point on you divide, for example in the picture the line is hitting (1.5,60) so you divide 60 by 1.5 and get 40 :)

Find the length of the third side. If necessary, round to the nearest tenth. 10 24
galben [10]

Answer:

26 units

Step-by-step explanation:

Pythagoras' Theorem: \sf a^2+b^2=c^2

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Given

  • a = 10
  • b = 24

Substitute the given values into the formula and solve for c:

\sf \implies 10^2+24^2=c^2

\sf \implies c^2=676

\sf \implies c=\pm\sqrt{676}

\sf \implies c=\pm26

Since length is <u>positive</u>, c = 26 only
