If #peaches = x and #plums = y we can write the following equations:

x+y=15
0.89x + 0.39y = 8.85

and x and y are whole numbers.

converting the first to x=15-y and plugging it into the second, you get

0.89(15-y) + 0.39y = 8.85 =>
13.35 - 0.89y + 0.39y = 8.85 =>
4.5 = 0.5y =>
y = 9

so x = 15-9 = 6

She bought 9 plums and 6 peaches.

How can i solve 2.3x10^-4-6x10^-5 with scientific notation
Lady bird [3.3K]
Convert 2.3 * 10^-4 and 4.6 * 10^-5 into decimals, obtain your solution; and finally, convert that number into scientific notation.

2.3 * (10^-4) = .00023
6 * 10^-5 = .00006

.00023 - .00006 = .00017

and finally, .00017 = 1.7 * 10^-4

Your answer is 1.7*10^-4

Hope this helps!

  • Horizontal line means parallel to x axis
  • It's passing through origin i.e (0,0)
  • Hence it lies on x axis .
  • Or its equal to x axis

So the equation is

  • y=0

Which of the following represents a geometric sequence?
grin007 [14]

Answer:

Option 1 is a geometric sequence.

I 1/4, 1/4, 1/4, 1/4

II      1/4, 1/5, 1/6

III     1/4, 1, -4, 1/6

IV     1/4, -4, 1/4, -4

For any geometric sequence there should be a common ratio

To find common ratio we divide consecutive terms

lets check option I

I 1/4, 1/4, 1/4, 1/4

When we divide 1/4 by 1/4 we will get 1

Same 1 for other two terms, so common ratio is 1

Hence the first option is a geometric sequence

The set of ordered pairs below represents a linear function.
vivado [14]

Answer:

(4,0)

Step-by-step explanation:

It is a linear function so you find the slope by doing y2-y1/x2-x1 and you find the slope to be 1/2. You can then setup an equation using it and graph it to find the next value.
