2. A(n)_______ has an infinite number of solutions.

asambeis [7]

Answer:

x+y+z=2 has no solutions. You can pick an arbitrary value for x4, and use that to calculate values for all the other variables so that all the equations will be satisfied. If you can set x4 to one of an infinity of real values, then you have an infinity of solutions

The perimeter of a rectangle is 72 cm. The length is 3 more than twice the width What

solmaris [256]

<h3>Solution</h3>

Given :-

Perimeter of rectangle = 72 cm
The length is 3 more than twice the width.

Find :-

Dimensions of rectangle

<h3 /><h3>Explantion</h3>

Using Formula

$\boxed{\underline{\tt{\red{\:(perimeter_{rectang}\:=\:2\times (Length+Width)}}}}$

Let,

Length of Rectangle = x cm
Breadth of Rectangle = y cm

According to question,

==> perimeter of Rectangle = 72

==> 2(x+y) = 72

==> x + y = 72/2

==> x + y = 36_________________(1)

Again,

==> x = 2y + 3

==> x - 2y = 3__________________(2)

Subtract equ(1) & equ(2)

==> y + 2y = 36 - 3

==> 3y = 33

==> y = 33/3

==> y = 11

keep in equ(1)

==> x - 2×11 = 3

==> x = 3 + 22

==> x = 25

<h3>Hence</h3>

Length of Rectangle = 25 cm
Width of Rectangle = 11 cm

To solve this system of equations using substitution, what could be substituted in place of y in the first equation? 4x = 5 − 2y

erik [133]

Answer:

y = $-\frac{4x-5}{2}$

Step-by-step explanation:

Step 1: Switch sides

5 - 2y = 4x

Step 2: Subtract 5 from both sides

5 - 2y - 5 = 4x - 5

Step 3: Simplify

-2y = 4x - 5

Step 4: Divide both sides by -2

$\frac{-2y}{-2} = \frac{4x}{-2} - \frac{5}{-2}$

Step 5: Simplify

y = $-\frac{4x-5}{2}$
