Y= 4x + 1

1 answer:

6 0

Solve one of the equations for x.
y = 4x + 1
y-1 = 4x
(y-1)/4 = x

Next, plug in this expression in the place of “x” in the previous expression
y = 2x - 5
y = 2((y-1)/4) -5
y = 1/2y - 11/2
1/2 y = - 11/2
y = -11

How do you solve t=1/8sv and solve for v?

Kruka [31]

Answer:

v = (8t)/s

Step-by-step explanation:

Divide both sides by 1/8, so multiply both sides by 8.

8t = sv

Divide both sides by s.

(8t)/s = v

Switch sides.

v = (8t)/s

If line L is parallel to plane P ,how many planes containing line L can be drawn parallel to plane P

PilotLPTM [1.2K]

Answer:

Only 1 plane containing line L can be drawn parallel to plane P.

Step-by-step explanation:

Line L is an axis of an infinite number of planes that can contain it. Line L is a straight line suspended over or below plane P.

All the planes that can contain line L would be almost infinte. Spinning around this axis of line L, the planes that can contain line L will be always be at an angle to plane P except for one position. In this position the plane containing Line L would face straight up to the plane P, hence, this is the only parallel case.

Hope this Helps!!!

What is the percent of change from 50 to 23?

Taya2010 [7]

Answer:

50 is the old value and 23 is the new value. In this case we have a negative change (decrease) of -54 percent because the new value is smaller than the old value. Using this tool you can find the percent decrease for any value.

A vacant city lot is being turned into a neighborhood garden. The neighbors want to fence in a triangular section of the lot and

Dennis_Churaev [7]

Step-by-step explanation:

=>>. Hello mate. (◕ᴗ◕✿)

= Given :-

perimeter of traingle = 58 feet

 let the third side be. "X" feet

  longest side = (2x - 8) feet

 shorter side = (x + 2) feet

Perimeter of traingle = sum of all three sides

=> A/q. ,

( x ) + ( 2x - 8 ) + ( x + 2) = 58. ✓✓✓

 x + 2x - 8 + x + 2 = 58

=>. 4x - 6 = 58

=> 4x = 58 + 6

=> 4x = 64

=>. x = 64/4

 =|. x = 16 feet

length of third side = 16 feet

length of shorter side = 18 feet

length of longest side = 24 feet

 Hope it helps you.......
