Answer:

Like terms means that the numbers have the same variable after them or they don't have a variable at all. It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.

For example, x + 3x = 1x +3x. Then I add the numbers in the front and I get 4x.

If it had been 4x + 7x + 3, my answer would have been 11x +3. That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.

Answer:

$8x$

Step-by-step explanation:

$x+7x$

$8x$

The answer is $8x$ when you simplify because you are adding another $x$ to $7x$ so it becomes $8x$

Figure 1 is dilated to get Figure 2.

Anastasy [175]

Answer: 2.25

Divide the corresponding values. You'll divide figure 2's length over figure 1's corresponding length. So 18/8 = 2.25

This means each side of figure 2 is 2.25 times larger than the corresponding side for figure 1

m = (y2-y1)/(x2-x1)

= (-5-1)/(4-2)

= -6/2
