Algebra?? Graphing!?!?! help 15 minutes i need the it by!?!

Graph the following linear inequalities. 1. y5x + 2 2. y4x + 2 3. y3x + 2 4. y2x + 2 5. y3x + - 2 6. y5x- 3-Well its been more than 15 minutes but here are the answers. These are all equations

Solve these two equations.

1) b^2 = 8 2) 3(x + 2)^2 - 4 = 11-3(x + 2)^2 - 4 = 11 3(x+ 2)^2 = 15 (x + 2)^2 = 5 x + 2 = ± √5 x = - 2 ± √5 check one problem at a time...read your textbook...practice-1) sqrt(b^2) = sqrt(8)

Write down the greatest integer value of 'y' which satisfies the inequality 2y-5 < 8

Theres a _ underneath the -2y-5 2y y y So the greatest integer y which satisfies the inequality 2y-5

How would I find the degrees of the following field extensions

i) Q(sqrt(11))/Q ii) Q(sqrt(11),sqrt(5))/Q iii) Q(sqrt(11),sqrt(5),sqrt(55))/Q-i) Since the minimal polynomial of √11 (which is x^2 - 11) is irreducible over Q and is of degree 2, we see that [Q(√11

Help with math problems

i have 3 math problems but i dont understand how to solve them 1.) solve by factoring, 4x^2-x-3=0 2.) simplify, x^2-4/x^2-3x+2 3.)simplify, c^2/de * 7d^4e/4c please explain how to do each problem

How do you solve these pair of simultaneous equations? 5x+4y= -6 and 2x+6y= 13

Multiply the first equation by 3:.... 15x + 12y = -18 Multiply the second equation by 2: 4x + 12y = 26 Subtract one from the other: 11x = -44 x = -4 Use this value in the first equation: 5(-4) + 4y =
