Answer:
8√2
Step-by-step explanation:
4√2 + 7√2 - 3√2 = (√2)(4 + 7 - 3) = 8√2
Recognize that √2 is a common factor and simply add its coefficients.

Answer:
x = 3
Step-by-step explanation:
5(2 - x) = 7x - 26
Distribute;
10 - 5x = 7x - 26
Add 5x to both sides;
10 = 12x - 26
Add 26 to both sides;
36 = 12x
Divide both sides by 12;
x = 3
Answer:
slope = -3; y-intercept = 1/2
Step-by-step explanation:
A way to solve this problem would be to write equations based off of the answer choices on the right, plug the x and y values from the chart into those equations, and see if they are true.
Let's look at the third option choice. Given that the slope = -3 and the y-intercept is 1/2, we can write an equation using the slope-intercept format, y= mx + b, where m is the slope and b is the y-intercept. So, the equation for that would be y= -3x + 1/2.
Let's try plugging in some x and y values and testing if they are true. Let's take the point 
from the chart for example:
So, since 
does equal to , it is true, making that the correct answer. You could plug in any other point from the chart to check, too - it's good to check multiple, but for the sake of brevity, I just put that as one example.
