Think about the axis for a moment. You have the y-axis and the x-axis. The y-axis crosses the x-axis at y=0. Consequently the graph must also cross the x-axis when its equation has its y-value set to 0.

Likewise the graph will cross the y-axis when x=0

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Solving your question

To find the x-intercept set y=0 giving

- 2x  + 5(0) =  - 10 \\  - 2x =  - 1 |?|

Multiply both sides by ( -1) giving

2x = 10

Divide both sides by 2 giving

\frac{2}{2}  \times x =  \frac{10}{2}  \\

But \frac{2}{2} = 1 \:   \\ giving

<h3>x =  \frac{10}{2} \\</h3>

Answer:

2x-5y=10 in slope intercept form is y=2/5x-2. The x intercept would be 5 and the y intercept would be -2. The slope is 2/5.

s344n2d4d5 [400]

Answer:

20 minutes per pound

Step-by-step explanation:

we know that

To find the unit rate divide the total time by the total weight

Convert mixed number to an improper fraction

16\frac{1}{5}\ lb=\frac{16*5+1}{5}=\frac{81}{5}\ lb

5\frac{2}{5}\ lb=\frac{5*5+2}{5}=\frac{27}{5}\ h

Convert hours to minutes

1\ h=60\ min

so

\frac{27}{5}\ h=\frac{27}{5}(60)=324\ min

Find the unit rate

\frac{324}{\frac{81}{5}}=\frac{1,620}{81}=20\ \frac{min}{lb}

therefore

20 minutes per pound

Please help! Determine where f(x) = g(x) by graphing.
Sloan [31]

Answer:

C

Step-by-step explanation:

We can point plot to get graph of both the functions.

<u><em>** Attached is the graph of both the functions. f(x) is in RED & g(x) is in BLUE.</em></u>

From the graph shown, it is clear that the point of intersection is x = 4, y = 2

So f(x) = g(x) at the point x = 4

Answer choice C is right.
