Plz help me i need help
natali 33 [55]
Ok so you know the first garden needs 1 and 2/5 bags of soil. Now first we need to find one fifth of that. So let's make this mied number into an improper fraction:

1 2/5 = 7/5

Ok now let's divide 7/5 by 5:

7/5 divided by 5/1 = 7/25

So Jared will need 7/25 bags of soil for his second garden, but we're STILL not done. now we have to add for the TOTAL.

1 2/5 + 7/25 > 7/5 + 7/25 > 7 x 5 = 35    > 35/25 + 7/25 = 42/25
                                           _________  
                                            5x 5 = 25

Now let's simplify it to 1 and 17/25

Find the zero of the function p(x) = 1/4x-3
harkovskaia [24]

Answer:

x = 12

Step-by-step explanation:

Given

p(x) = \frac{1}{4} x - 3

To find the zero let p(x) = 0, that is

\frac{1}{4} x - 3 = 0 ( add 3 to both sides )

\frac{1}{4} x = 3 ( multiply both sides by 4 )

x = 12 ← zero of p(x)

What is the domain of the function represented by the following graph?
Svetllana [295]

Hello!

The domain of the function are the x-values that make the function true.

Since the graph has open circles and filled in circles, the open circles make the function false (written as <) , and the filled in circles make it true (written as ≤).

From the graph, the x value -3, and 2 are open circles. While the value -0.5 are filled in circles. Also, from the interval (-0.5, 2), there is gap, so it is part of the domain.

Therefore, the domain of the function is: {x | -3 < x ≤ -0.5} ∪ {x | 2 < x < ∞}, which is the third choice.
