3x + 2y = -26 ........(1)

2x - 6y = -10........(2)

Multiplying (1) by 3

= 9x + 6y = -26

Adding (1) and (2)

= 9x + 6y = -78

= 2x - 6y = -10    (+)

---------------------------

11x = - 88

x = -8

Substituting x in (2)

-16 - 6y = -10

-6y = 6

y = -1

Show all work to factor x^4-10x^2+9 completely
dimaraw [331]

Answer:

(x^{2}-9)(x^{2} -1)

Step-by-step explanation:

Step 1: Find what adds to _ and multiples to_

It needs to multiple to the 'c' term or 9

It needs to add to the 'b' term or -10

Step 2: Find the numbers

We know -9 and -1 make 10 and multiple to 9

-9 x -1 = 9

-9 + (-1) + -10

Step 3: Write equation in form a(x-r)(x-s)

a = 1

r = -9

s = -1

Plug in the equation to get the factored form of the equation:

(x^{2}-9)(x^{2} -1)

Therefore the factored form of the equation is (x^{2}-9)(x^{2} -1)

svetlana [45]

Answer:

59/350

Step-by-step explanation:

Under his cell phone plan, Ethan pays a flat cost of $59 per month and $5 per gigabyte. He wants to keep his bill under $70 per month. Write and solve an inequality which can be used to determine x, the number of gigabytes Ethan can use while staying within his budget.​

so say that you have 59$ as a flat cost do when you have a problem like this its kinda easy but what you are going to do is take 59 and divide 5 and see what you get you are going to get 11.8 then divide 11.8 into 70 and see what you get then lets see you would get a number that is a fraction answer sis at top.  

Glad i could help you have a nice day!!!
