What is the equation of the line that passes through (1, 2) and is parallel to the line whose equation is 2x+y-1=0?
tresset_1 [31]

Answer:

The equation of the line that passes through (1, 2) is y = - 2x + 4

Step-by-step explanation:

2x + y - 1 = 0

2x + y - 1 + 1 = 0 + 1

2x + y = 1

2x - 2x + y = 1

y = - 2x + 1

parallel lines have the same slope, so the equation line will be -2

plug in the point, y = mx + b    (x, y)

y = (-2)x + b , (1, 2)

(2) = (-2)(1) + b

2 = -2 + b

2 + 2 = -2 + 2 + b

4 = b

y = - 2x + 4

H=-16t^2+46t+6 after how many seconds will the ball hit the ground?
ANEK [815]
Ball hit the ground is when the function equals zero
0=-16t^2+46t+6
we can't factor so use quadraticformula

for
ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^2-4ac} }{2a}
x=\frac{-46+/- \sqrt{46^2-4(-16)(6)} }{2(-16)}
x=\frac{-46+/- \sqrt{2116+384} }{-32}
x=\frac{-46+/- \sqrt{2500} }{-32}
x=\frac{-46+/- 50 }{-32}
x=\frac{-46+ 50 }{-32} or \frac{-46- 50 }{-32}
x=\frac{4}{-32} or x=\frac{-96}{-32}
x=-1/6 or x=3

we cannot have negative time because time starts at 0
disregard -1/6 as a possible answer


answer is after 3 seconds
