If you're taking trig, the "sum and difference formulas for trig functions" are basic facts that you'll need to learn and commit to memory. I'd suggest you look up these formulas on the net. You will likely immediately find listings for the sine, cosine and tangent.
Answer:
y = 2x + 2
Step-by-step explanation:
The equation ofa line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 4 ← is in slope- intercept form
with m = 2
Parallel lines have equal slopes , thus
y = 2x + c ← is the partial equation
To find c substitute (3, 8) into the partial equation
8 = 6 + c ⇒ c = 8 - 6 = 2
y = 2x + 2 ← equation of parallel line
Answer:
11 ÷ 27 = 0.407407
Step-by-step explanation:
Una fracción, como 11/27, tiene un numerador y un denominador separado por una línea divisoria.
11 es el numerador, porque es el número de arriba de la línea divisoria.
27 es el denominador porque es el número de abajo de la línea divisoria.
Para convertir 11/27 a decimal, divide el numerador por el denominador.
Answer:
Step-by-step explanation:
-17(y - 2) = -17y + 64
-17y + 34 = -17y + 64
-17y + 17y = 64 - 34
0 = 30 (incorrect)
this system has NO SOLUTIONS
Just use distance formula for each point and plug it in p=a+b+c
