Step-by-step explanation:

The problem states that you have a linear function so expect your equation to have this form:

y = mx + b

where m is the slope and b is the y-intercept. You are also given two points: P1(5, 6) and P2(14, 60). Use these points to solve for the slope m.

m = (y2 - y1) / (x2 - x1) = (60 - 6)/(14 - 5)

= 54/9 = 6

So our equation now becomes

y = 6m + b

To solve for b, plug in the values of P1:

6 = 6(5) + b ---> b = -24

Therefore, our equation is

y = 6m - 24

The rest of the points are

(8, 24)

(11, 42)

Are the two expressions equivalent when x=5
adell [148]

Answer:

Yes

Step-by-step explanation:

The first one is 35+15 because 7*5 is 35 and 3*5 is 15

The second one is 45+5 because 9*5=45

35+15=50

45+5=50

Yes, they are equal.

There is a total of 36 books on the bookshelf. The number of hardback books is 15 more than twice the number of paperback books.
uranmaximum [27]

The number of hardback books that are on the bookshelf is 29 books.

  • Let the total number of books be T.
  • Let the number of hardback books be H.
  • Let the number of paperback books be P.

<u>Given the following data:</u>

  • Total number of books = 36 books

To determine the number of hardback books that are on the bookshelf:

Translating the word problem into an algebraic expression, we have;

The total number of books is:

T = H+P

The number of hardback books is 15 more than <u>twice</u> the number of paperback books:

H =2P+15

Substituting the given parameters into the formula, we have;

36 = 2P+15+P\\\\36=3P+15\\\\3P=36-15\\\\3P=21\\\\P=\frac{21}{3}

P = 7 books

For number of hardback books:

H =2P+15\\\\H=2(7)+15\\\\H=14+15

H = 29 books

20x2 + 3x + 5 = 7<br><br> Help
Mrac [35]

Answer:

3/20, -3/10

Step-by-step explanation:

Its a quadratic equation, use the quadratic formula. (-b+-\sqrt{b^2-4ac\\})/2a

20x^2+3x-2=0

(-3+-\sqrt{9+80})/40

(-3+-9)/40

So you get 6/40=3/20 and -12/40=-3/10
