Solve the system by graphing  

{y = 7 - x   the slope is -1 and the y intercept is 7

{x + 3y = 11   3y = -x+11  y = 1/3 x + 11/3  the slope is 1/3 and the y intercept is 11/3

The solution is x=5, y=2   you will need to graph



Classify the system without graphing

{2x + y = 3      y = -2x+3      

{y = -2x - 1

These lines are parallel   same slope different y intercept

C) Inconsistent System



Classify the system without graphing  

{x + 3y = 9

{-2x - 6y = -18   divide by -2

x+3y = 9

same line

A) Dependent System

Please help me I will give you extra points and the brain thing
vovangra [49]

Answer:

A. n = 5

Step-by-step explanation:

S = n² + n

When S = 30:

                                                       n² + n = 30

Subtract 30 from both sides:  n² + n - 30 = 0

Factorize:                               (n - 5)(n + 6) = 0

Therefore                                                 n = 5 or -6

As n > 2, then n = 5 only

The perimeter of a rectangle is 80 inches, if the width is 18 inches what is the area of the rectangle? A.22 sq.in B.324 sq.in C
Tanya [424]

Answer:

396 in^2

Step-by-step explanation:

The perimeter of a triangle is given by the formula:

● P = 2w+2L

L is the length and w is the width

■■■■■■■■■■■■■■■■■■■■■■■■■■

The width hereis 18 inches and the perimeter is 80 inches.

Replace w by 18 and P by 80 to find L.

● P= 2L+2w

● 80 = 2L + 2×18

● 80 = 2L + 36

Substrat 36 from both sides

● 80-36 = 2L+36-36

●44 = 2L

Divide both sides by 2

● 44/2 = 2L/2

● 22 = L

So the length is 22 inches

■■■■■■■■■■■■■■■■■■■■■■■■■■

The area of a rectangle is given by the formula:

● A= L×w

● A = 22×18

● A = 396 in^2
