Answer:

y=2/7x+19/7

Step-by-step explanation:

Slope = m = (y₂-y₁)/(x₂-x₁) = (5-3)/(8-1) = 2/7

Therefore, our equation so far is y=2/7x+b where we can calculate b, the y-intercept by plugging in one of our given points [I used (1,3)]:

y=2/7x+b

3=2/7(1)+b

3=2/7+b

21/7=2/7+b

19/7=b

Therefore, our final equation is y=2/7x+19/7

Answer:

  • 20 crocus
  • 40 daffodil

Step-by-step explanation:

Let d represent the number of daffodil bulbs you buy. Then 60-d is the number of crocus bulbs. The total cost will be ...

  0.45(60 -d) +0.65(d) = 35.00

  27 +0.20d = 35

  0.20d = 8 . . . . . . . . . subtract 27

  d = 40 . . . . . . . . . . multiply by 5

  60 -40 = 20 . . . . . crocus bulbs

You can buy 20 crocus bulbs and 40 daffodil bulbs for $35.

Write in exponential notation 6 times 6 times 6 times 6 times 6
Darina [25.2K]
Exponent form : 6^5

explanation :
we are given five 6's , so we simply start out with the number that is being multiplied over and over again .
which in this case , is 6.

6 • 6 • 6 • 6 • 6 = 7776

To make things easier though, we write repetitive numerals in exponent form. You will still get the same answer either way .

6^5 = 7776

answer : 6^5
