Simplify 7x + 2y = -23
Solving
7x + 2y = -23
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
7x + 2y + -2y = -23 + -2y
Combine like terms: 2y + -2y = 0
7x + 0 = -23 + -2y
7x = -23 + -2y
Divide each side by '7'.
x = -3.285714286 + -0.2857142857y
Simplifying
x = -3.285714286 + -0.2857142857y

Answer:
10 is the constant
y = 4x + 10
Step-by-step explanation:
Y is the y- intecerpt
x is the slope.
constant is any number by itself no x no nothing since 4 is the slope and has X the constant is the y-intercept which is 10.
Answer:
See below ~
Step-by-step explanation:
Identities :
- cot x = cos x / sin x
- sin²x + cos²x = 1
Changing the Left Hand Side (LHS) :
- 1/cot x + cotx
- 1/(cos x / sin x) + cos x / sin x
- sin x / cos x + cos x / sin x
- Take (sin x)(cos x) as the LCM (Least Common Multiple)
- sin x (sin x) + cos x (cos x) / (sin x) (cos x)
- sin²x + cos²x / cos x sin x
- 1/cos x sin x
- Equal to the RHS
