What would the graph of 10x + 7y < 49 look ?

navik [9.2K]

Answer: The graph is attached.

Step-by-step explanation:

1. Solve for y, as following:

$10x+7y$

2. The equation of the line in slope intercept form is:

$y=mx+b$

Where m is the slope and b is the y-intercept.

3. In this case the equation of the line is:

$y=-\frac{10}{7}x+7$

then:

$m=-\frac{10}{7}\\\\b=7$

4. Find the x-intercept. Make y=0. Then:

$0=-\frac{10}{7}x+7\\\frac{10}{7}x=7\\x=4.9$

5. Then, plot the line that passes through the points (0,7) and (4.9, 0).

6. The symbol of the inequality is < therefore, the line must be dashed and indicates that the region under the line must be shaded.

Then you obtain the graph attached.

If f(x) = x2 – 2x, find:<br> f(-3) = [?]

allsm [11]

Answer:

$\boxed{\sf f(-3) = 9}$

Given:

$\sf f(x) = {x}^{2} - 2x$

To Find:

Value of f(x) when x = -3

Step-by-step explanation:

$\sf \implies f(x) = {x}^{2} - 2x \\ \\ \sf \implies f( - 3) = {( - 3)}^{2} - 2 ( - 3) \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3 - ( - 6) \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =3 + 6 \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =9$
