6. Find an equation of the line through (1,-6) parallel to the line x+2y = 6. 7. Find an equation of the line through (2, – ſ) perpendicular to the line
4x – Sy = 1.
8. Determine whether these two lines are parallel: y = 2x+3 and 2y - 4x –
5=0.
9. Test the equation y - 10x = x3 for all three types of symmetry.
10. Test the equation y = x2 + |2| for all three types of symmetry.

the answer is vanilla

step-by-step explanation:

answer: x=3 and y=4

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
