4x - 1 < 7 i don’t know what to do

Olin [163]

4x - 1 < 7

To solve for x:

4x - 1 + 1 < 7 + 1

4x < 8

Divide both sides by 4:

4x/4 < 8/4

x < 2

How do you round off 639,121 to the nearest ten thousand?

maxonik [38]

You want to find the closest ten thousand that there is to 639,121.

So a ten thousand is basically anything that ends with four or more zeros.

For example:

530000 would be a ten thousand because it has four zeros at the end.

So you can see what the closest ten thousands are to 639,121 would be.

They would be:

630,000 and 640,000

Since they both have four zeros at the end.

Now you can just tell that 639,121 is closer to 640,000 because the digit in the thousands place, 9, is closer to 10 than 0.

Hope this helped :)

Graph the solution to the following linear inequality in the coordinate plane 5x-y>-3

Irina18 [472]

Answer:

Here's one way to do it

Step-by-step explanation:

1. Solve the inequality for y

5x - y > -3

-y > -5x - 3

y < 5x + 3

2. Plot a few points for the "y =" line

I chose

$\begin{array}{rr}\mathbf{x} & \mathbf{y} \\-2 & -7 \\-1 & -2 \\0 & 3 \\1 & 8 \\2 & 13 \\\end{array}$

You should get a graph like Fig 1.

3. Draw a straight line through the points

Make it a dashed line because the inequality is "<", to show that points on the line do not satisfy the inequality.

See Fig. 2.

4. Test a point to see if it satisfies the inequality

I like to use the origin,(0,0), for easy calculating.

y < 5x + 3

0 < 0 + 3

0 < 3. TRUE.

The condition is TRUE.

Shade the side of the line that contains the point (the bottom side).

And you're done (See Fig. 3).
