Answer:

3. x = y - 3

Step-by-step explanation:

You want to move all numbers on the same side of x to the other side with y. Whenever doing this, we have to reverse the operation. In this problem, we have + 3 with x. So we will need to subtract 3 from both sides.

x + 3 = y

x = y - 3

Find the distance between the pair of points (2,9) and (3,8).

xxTIMURxx [149]

Answer:

$\sqrt{2}$ units

Step-by-step explanation:

To find the distance between a pair of points, use the distance formula, $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ . Substitute the x and y values of (2,9) and (3,8) into the formula and simplify:

$d = \sqrt{(8-9)^2+(3-2)^2} \\d = \sqrt{(-1)^2+(1)^2} \\d = \sqrt{1+1} \\d= \sqrt{2}$

So, the distance is $\sqrt{2}$ units.

Write the inequality: The sum of x and 10 is less than -4

andrezito [222]

Answer:

x + 10 < -4

Step-by-step explanation:

x + 10 is less than -4, so -4 would have to be greater. You would put x + 10 on the left side and on the right side would be -4. In between would be a less than sign because x + 10 is LESS than -4.
