Kx+9=7
Kx=-2 (subtract 9 from both sides)
X=-2/k (divide k from both sides.
Step-by-step explanation:

Answer:
x = 35 - y / 15
Step-by-step explanation:
3x + 1/5y = 7
3x + 1/5y - 1/5y = 7 - 1/5y
3x = 7 - 1/5y
3x/3 = 7/3 - 1/5y / 3
x = 35 - y / 15
Here, the 5 in the denominator of the first term will be cancelled out with the 5 of the numerator of the second term and the result would be 5/3. Since 5/3 cannot be further simplified, therefore, the final result is 5/3
5/10*10/3 = 5/3
Answer:
0.249
Step-by-step explanation:
tan(theta) = opposite / adjacent (according to the SOH CAH TOA rule), which effectively means y/x in this case.
So -0.242 / -.970 ≈ 0.249
Other explanation:
On a unit circle,
y = sin(θ)
and
x = cos(θ).
And since, tan = sin/cos, tan(θ) = y/x. You y and x are given, so calculating tan is a matter of dividing them.
