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.

What is the least common multiple of 8 and 9?<br><br><br><br> Enter your answer in the box.
Contact [7]

Answer:

72

Step-by-step explanation:

The LCM is when you find the lowest factor that 2 or more numbers share.

For 8 and 9,you would just need to keep multiplying each other until you find the same numbers. It would look something like this.

8,16,24,32,40,48,56,64,72..... etc.

9,18,27,36,45,54,63,72,81..... etc.

You can see how they both have the same factor (72), and since that is the lowest factor (which means I can find a lower factor then 72) then your LCM of 8 and 9 should be 72 :)
