HELPPPPPPP MEEEEE BUT PUT THE CORRECT ANSWER

Mathematics
1 answer:
Elenna [48]3 years ago
3 0

Answer:

\sf 3\left[-x+\left(2x+1\right)\right]=x-1

\sf 3\left(-x+2x+1\right)=x-1

Combine like terms:

\sf -x+2x=x

\sf 3\left(x+1\right)=x-1

Expand:

\sf 3x+3=x-1

Subtract 3 from both sides:

\sf 3x+3-3=x-1-3

\sf 3x=x-4

Subtract x from both sides:

\sf 3x-x=x-4-x

\sf 2x=-4

Divide both sides by 2:

\sf \cfrac{2x}{2}=\cfrac{-4}{2}

\boxed{\boxed{ \sf x=-2}}

Derive the equation of the parabola with a focus at (6,2) and a directrix of y=1
nydimaria [60]
Distance from focus to vertex=distance from vertex to directix

from (6,2) to y=1, the distance is 1
the focus is 1/2 higher than the vertex
vertex=(6,1.5)

for
(x-h)^2=4p(y-k)
vertex=(h,k)
p=distance from vertex to directix

vertex=(6,1.5)
ditance=0.5

(x-6)^2=4(0.5)(y-1.5)
(x-6)^2=2(y-1.5) is the equation
or
y=0.5x^2-6x+19.5 or
y=0.5(x-6)^2+1.5

barxatty [35]

Answer:

Restating the question clearly:

Ben drinks tea at an incredible rate. He drinks 3 1/2 liters of tea every 2/3 of an hour. How much does he drink in one hour?

Answer:

He drinks  5\frac{1}{4}\ liters\  in 1 hour

Step-by-step explanation:

Rate\ of\ drinking\ =\ 3\frac{1}{2}\ liters\ per\ \frac{2}{3}\ of\ an\ hour\\\therefore\ 3\frac{1}{2}\ liters\ is\ consumed\ in\ \frac{2}{3} \ hours\\\frac{7}{2} \ liters = \frac{2}{3} \ hours\\cross-multiplying\\7 \times 3\ liters = 2 \times 2\ hours\\21\ liters = 4\ hours\\4\ hours\ = 21\ liters\\\therefore\ for\  1\ hour\\\frac{4}{4}\ hours = \frac{21}{4}\ liters\\1\ hour = 5.25\ liters\\5.25\ liters = 5\frac{1}{4}\ liters
