What is the solution to the system of equations that contains -3x + y = 3 and 2x - y = -1

1 answer:

5 0

-3x + y = 3
2x - y = -1

2x - 2x - y = -1 - 2x
-y = -1 - 2x
Y = 1 + 2x
Y = 2x + 1

-3x + y = 3
-3x + (2x + 1) = 3
-3x + 2x + 1 = 3
-X + 1 = 3
-X + 1 - 1 = 3 - 1
-X = 2
X = -2.

Y = 2x + 1
Y = 2(-2) + 1
Y = -4 + 1
Y = -3.

P(-2,-3). The solution to this system of equations is P(-2,-3).

You have a 32-foot fence around a square garden. You paint 1/3 of one side of the fence. What fraction of the fence did you pain

dmitriy555 [2]

The answer is 1/12.

The perimeter of a square garden with side s is:
P = 4s

s = 1/4P

Since it is painted 1/3 of 1/4 of the fence, the<span> fraction of the painted fence is:
1/3 * 1/4 = 1/12</span>

Now, that you have the new wheel circumference, what will happen to the number of rotations if the circumference of the tires we

butalik [34]

The number of rotations for the new wheel will be 1,056 rotations

<h3>How to calculate the circumference of a wheel?</h3>

Let the initial circumference be 50 rotations (assumed)

If the number of rotations of the circumference of the tires were increased by 20%, then the new circumference will be:

Ne circumference = 1.2 * 50 = 60

number of rotations for the new wheel = 63360/60
number of rotations for the new wheel = 1,056 rotations

Hence the number of rotations for the new wheel will be 1,056 rotations

Diano4ka-milaya [45]

Answer:

dC = 2.44

Relative error = 19%

Step-by-step explanation:

$C = 35.74 + 0.6215*T - 35.75*v^(0.16) + 0.4275*T*v^(0.16)$

Δv = 3 ; ΔT = 1 , v = 23, T = 8

Use differential Calculus

$dC = Cv.dv + Ct.dt$

$Cv = dC/dv = -5.72*v^(-0.84) + 0.0684*T*v^(-0.84)\\Ct = dC/dT = 0.6215 + 0.4275*v^(0.16)\\dC = modulus (Cv.dv) + modulus (CT.dT)\\dC = (-5.72*v^(-0.84) + 0.0684*T*v^(-0.84))* 3 + (0.6215 + 0.4275*v^(0.16))*1\\dC = 2.44$

Relative Error

dC / C @(T = 8, v=23) * 100 = 19 %
