30 and 13


x-y=17 and x+y=43

x=17+y and x=43-y, so 17+y=43-y

so y=13

43-13=30, so x=30 and y=13

Find an equation for the line with slope m = -6/7<br> and which goes through the point (14, 4).
sammy [17]

Answer:

y = -6/7x + 16

Step-by-step explanation:

Use the slope intercept equation, y = mx + b

Plug in the slope and given point, then solve for b:

y = mx + b

4 = -6/7(14) + b

4 = -12 + b

16 = b

Plug in the slope and b into the equation:

y = mx + b

y = -6/7x + 16

So, the equation is y = -6/7x + 16

Prove that sin x cos x = cot x is not a trigonometric identity by producing a counterexample.
BaLLatris [955]

Answer:

see below

Step-by-step explanation:

sin x cos x = cot x

We need to show a counter example

Let's use 30 degrees

sin 30 cos 30 = cot 30

1/2 * sqrt(3) /2 = sqrt(3)

sqrt(3)/4 = sqrt(3)

not true
