  • It's very long so I'm not giving answers but here's how i would do it:
  1. use Pythagoras a^2 +b^2 = c^2 where c is the longest side
  2. use sine rule \frac{a}{sin(A)} = \frac{b}{sin(B)} = \frac{c}{sin(C)} where lower cases are the sides, and capitals are their opposite angles.

e.g for 15:

a = 3, b is missing, c = 10

A is missing, B is ?, C is 90

Which linear function has a negative slope, f(x) or g(x)? ​
Anit [1.1K]

Answer:

f(x) is negative and g(x) is positive

Step-by-step explanation:

f(x) = 4-x

Rewriting

f(x) = -x+4

We recognize this as

y= mx+b or the representation of a line with slope -1 and y intercept 4

f(x) is linear

g(x)  as we increase x by 1 we increase g(x) by 2

The slope is 2, and the y intercept is 1

y = 2x+1

Lets check a point

(2,5)

5 = 2(2)+1

5=5  so we are correct

f(x) is negative and g(x) is positive
