Answer:
x = 62.9° (3 sig. fig.)
Step-by-step explanation:
Simply by using the cos law,
cosx = (1.3² + 2.1² - 1.9²)/2(1.3)(2.1)
x = 62.9° (3 sig. fig.)
The slope intercept formula: y=mx + b
2y - 8x = 20 ∫ Add 8x to both sides to make the equation suitable∫
2y = 8x + 20 ∫Divide both sides by 2∫
∵ y= 4x + 10 ∵

It should cost $1.65 for each large drink.
You subtract $12 to $16.95 and that would give you 4.95 and divide it to the number of drinks they bought which is 3 and that would give you $1.65

The expression you want to simplify is 0-(x-y).
0-(x-y)
=-(x-y)
=-x+y
You just have to treat the negative sign in front of (x-y) as a -1 and distribute it to both x and -y.
