−9x+4y=6 9x+5y=−33

blsea [12.9K]

Answer:

{x,y} = {-2,-3}

Step-by-step explanation:

System of Linear Equations entered :

[1] -9x + 4y = 6

[2] 9x + 5y = -33

Graphic Representation of the Equations :

4y - 9x = 6 5y + 9x = -33

Solve by Substitution :

// Solve equation [2] for the variable y

[2] 5y = -9x - 33

[2] y = -9x/5 - 33/5

// Plug this in for variable y in equation [1]

[1] -9x + 4•(-9x/5-33/5) = 6

[1] -81x/5 = 162/5

[1] -81x = 162

// Solve equation [1] for the variable x

[1] 81x = - 162

[1] x = - 2

// By now we know this much :

x = -2

y = -9x/5-33/5

// Use the x value to solve for y

y = -(9/5)(-2)-33/5 = -3

Describe the relationship between the terms in each arithmetic sequence. Then

shtirl [24]

Answer:

(a) The sum of the previous term and 9

(b) 36, 45, 54

Step-by-step explanation:

Given

Sequence: Arithmetic Progression

$0,9,18,27$

Solving (a): Describe the relationship in each term

First, we calculate the common difference (d)

In arithmetic progression:

$d = T_n - T_{n-1}$

Take n as 2

$d = T_2 - T_{2-1}$

$d = T_2 - T_{1}$

Where

$T_2 = 9\ and\ T_1 = 0$

$d =9-0$

$d =9$

The relationship is: The sum of the previous term and 9

Solving (b): The next three terms

As said in (a) each term is derived from a sum of 9 and the previous term

So, we have:

$Next\ Term = 27 + 9 = 36$

$Next = 36 + 9 = 45$

$Next = 45 + 9 = 54$

Hence, the next three terms are: 36, 45 and 54

A mattress store in Stafford purchased a mattress at a cost of $255 and marked it up 100%. Later on, Cassie bought the mattress.

skad [1K]

Answer: 278.18

sorry if it's wrong

Step-by-step explanation: if you divide 255 by 11 you get 23.18181818181

so if you simplify you get 23.18 so that is the tax plus the original payment which is 278.18

Find the area and perimeter.

lara [203]

Answer:

Step-by-step explanation:

Perimeter of triangle = 4x - 3 + x + 9 + 8

= 4x + x - 3 + 9 + 8

= 5x + 14

Area = $\frac{1}{2}*base *height$

$= \dfrac{1}{2}*8*3x\\\\= 4 * 3x\\\\= 12x$
