Direct Variation<span>. Directly Proportional. A relationship between two variables in which one is a constant multiple of the other. In particular, when one variable changes the other changes in proportion to the first. If b is directly proportional to a, the equation is of the form b = ka (where k is a constant).</span>
4 pizzas bc 20 people each have 2 slices and 20 times 2 is 40
Answer:
x = -1
Step-by-step explanation:
2(x + 3) - 4 = 0
2x + 6 - 4 = 0
2x + 2 = 0
2x = 0 - 2
2x = -2
x = -2 ÷ 2
x = -1
Okay, so you see that linear pair formed of angle 1,2,3
Now <1 = <5 and <3 = <6
So if 1 = 5, and 3 = 6
We also know that linear pair has 180 degrees and Hence proved angle 6,5 and 2 is equal to 180 degrees
