Find an equation of the line parallel to y= 1/3x +1 and that passes through the point (3,5)

1 answer:

6 0

So in order to find the line you’ll have to submit the point (3,5) and the slope into the point slope formula : y-y1= m(x-x1)

Y-5= 1/3(x-3)

Solve(turn to y intercept form):

Y-5= 1/3x -1

ABCD is a rectangle. if AC = 3y/5 anf BD= 3(y-4), find the length of each diagonal

Digiron [165]

Remember please that Diagonals of a Rectangle are equal to each other: 3y/5 = 3(y-4)
So
3y = 15(y-4)
3y = 15y - 60
60 = 12y
y = 5 Diagonals are both 3 units
With that you will be able to know which is the answer from your options

Me ayudan con esa ecuacion por sustitucion con la comprobacion pliss

attashe74 [19]

1/2x+3y/4=5 => (1/2)x + (3/4)y = 5

1/5x+3y/2=2 => (1/5)x + (3/2)y = 2

Eliminate the fractional coefficients: Mult. the first equation by 4 and mult. the second equation by 10:

2x + 15y = 20

Multiply the 1st equation by -1:

-2x - 3y = -20
2x + 15y = 20
-------------------
12y = 0, so y = 0. Then the first equation becomes 2x + 3(0) = 20, or
x=10.

Solution is (10,0).

Using the speed - distance relationship, the time left before the appointed time is 27 minutes.

Recall :

Distance = speed × time

Let time = t

At 10mph :

Distance = 10 × (t + 3) = 10t + 30 - - - (1)

At 12 mph :

Distance = 12 × (t - 2) = 12t - 24 - - - - (2)

Equate (1) and (2) :

10t + 30 = 12t - 24

Collect like terms

10t - 12t = - 24 - 30

-2t = - 54

Divide both sides by - 2

t = 54 / 2

t = 27

Hence, the time left before the appointed time is 27 minutes.
