Sine, Cosine, Tangent, Cosecant (opposite of Sine), Secant (opposite of Cosine), and Cotangent (opposite of Tangent)
Answer:
ab = 2
Step-by-step explanation:
Given equations
ax² +ax + 2 = 0
x² + x + b = 0
root of both the equation
x= 1
then we can plug in x = 1 in both the equation
ax² +ax + 2 = 0 x² + x + b = 0
a*1² +a*1 + 2 = 0 1² + 1 + b = 0
a +a + 2 = 0 1 + 1 + b = 0
2a + 2 = 0 2 + b = 0
2a = - 2 b = -2
a = -2/2 = -1
Thus,
a = -1
b = -2
a*b = -1*-2 = 2
ab = 2
Answer:
To make a table u need to have coordinates, (x, y).
Solve for them using substitution:
y = x - 4 ↔ x = y + 4
y = (2x - 17)
PLUG IN TO y = (2x - 17).
y = (2(y+4) - 17)
Solve for y:
y = 2y + 8 - 17
y = 2y - 9
-1y = -9
y = 9
Solve for x:
x = (9) + 4
x = 13
Keep solving for x and y to have your coordinates for your table.
