34kurt

Answer:

8/23 cups of water for each plant. (Approx. 0.35 cups for each plant)

(I do hope this is correct)

Step-by-step explanation:

Since Lynn only filled half of her watering can full, it is now holding 8 cups pf water, since 16/2=8. Then, if she water each of her 23 plants equally, so each plan will supposedly get 8/23 cups of water.

3. Given the graph below, determine whether each statement is true or false.
MaRussiya [10]

Answers:

  1. True
  2. True
  3. True
  4. False
  5. False

======================================

Explanation:

In this context, a zero is another term for x intercept or root. This is where the graph either touches or crosses the x axis. This occurs in three locations: x = -3, x = 2, and x = 0. So those are the three roots. That makes the first three statements true, while the remaining two others are false.

Side note: x = 0 doesn't always have to be involved. Its quite possible to have x = 0 not be an x intercept. The term "zero" is a bit misleading in that regard. I prefer either "root" or "x intercept" instead.

Which of the following is the solution of One-fourth x + 5 = 7? x = 2 x = 6 x = 8 x = 12
salantis [7]
Changes made to your input should not affect the solution:

(1): "x1" was replaced by "x^1". 3 more similar replacement(s).

Step by step solution :

Step 1 :

Equation at the end of step 1 :

x + ((((3•19x2) • x6) • x8) • x12)
Step 2 :

Step 3 :

Pulling out like terms :

3.1 Pull out like factors :

57x28 + x = x • (57x27 + 1)

Trying to factor as a Sum of Cubes :

3.2 Factoring: 57x27 + 1

Theory : A sum of two perfect cubes, a3 + b3 can be factored into :
(a+b) • (a2-ab+b2)
Proof : (a+b) • (a2-ab+b2) =
a3-a2b+ab2+ba2-b2a+b3 =
a3+(a2b-ba2)+(ab2-b2a)+b3=
a3+0+0+b3=
a3+b3

Check : 57 is not a cube !!


Final result :

x • (57x27 + 1)
