Hello.

y<-1

The sign "<" means "less than"

The solutions of the inequality are less than -1.

For example, -2 is a solution of the inequality (it makes the inequality true)

The numbers that don't make the inequality true are greater than -1.

For example, let's take 3.

3 is greater than -1.

Plug it into the inequality:

3<-1

As we can see, we have a false statement.

Therefore, the answer is:

I hope this helps.

Have a nice day.

Y > = 2 | x - 1| - 2...subbing in (1,0)
0 > = 2 | 1 - 1| - 2
0 > = 2 (0) - 2
0 > = -2...correctso (1,0) is part of the solution

y > | x + 1| - 1...subbing in (1,1)
1 > | 1 + 1| - 1
1 > 2 - 1
1 > 1incorrectso (1,1) is not part of the solution

less then or equaldashed line, shaded below

x = cashier job hrs, y = babysitting hrs
y > = 0

6x + 6y = 60

To help solve the trigonometric inequality 2sin^2(x)+. cos(2x)-2 -1, Tracey successfully graphed the equations y=2sin^2(x) +cos(2x)-2 and y=-1 with her graphing calculator. Which of the following statements is true about the inequality? a. There is no solution because even though you cannot see it, the graph of the equation y=2sin^2(x) +cos(2x) -2 is above the graph of the equation y=-1 for all values of x. b. There is no solution because the graph of the equation y=2sin^2(x) +2cos(x)-2 is the same as the graph of the equation y=-1, so y=2sin^2(x)

B

Step-by-step explanation: I took the quiz and got it right

Also, if you graph the equations on a graphing calculator, the lines are right on top of each other, so the first equation can't be less than -1, so no solutions

Hello, I can give you some help w/ steps below! Hope this helps a lot :D

1.

8x < 48 || divide 8 on both sides of the equal sign

x < 6 || final answer, so your correct

2.

10 + x > 23 || subtract 10 on both sides of the equal sign

x > 13 || final answer, so your correct

3.

x - 14 < 28 || add 14 on both signs of the equal sign

x < 42 || final answer

4.

$\frac{y}{21}$ < 3 || multiply 21 on both sides

y < 63 || final answer

5.

2p < 18 || divide 2 on both sides of the equal signs

p < 9 || final answer

6. i have no idea how to do this one, sorry!

Is (0,0) a solution to this system? ya x2-4 y 2x-1 A. No. (0,0) satisfies yz x2 - 4 but does not satisfy y 2x-1. B. No. (0,0) satisfies y 2x - 1 but does not satisfy ya x2 - 4. C. Yes. (0,0) satisfies both inequalities. D. No. (0,0) does not satisfy either inequality.

Step-by-step answer

P Answered by Specialist

The answer is A.

Step-by-step explanation:

You have to substitute (0,0) into the inequalities equation to see whether it satisfy both equations :

EQUATION 1 :

$y \geqslant {x}^{2} - 4$

$0 \geqslant {0}^{2} - 4$

$0 \geqslant - 4 \: (satisfy)$

EQUATION 2 :

y < 2x - 1

0 < 2(0) - 1

$0 < </strong<strong-</strong<strong </strong<strong1 \: (not \: satisfy)$

Therefore, (0,0) satiafy equation 1 but not equation 2.

[100 points] question 1) the graph for the equation y = 2x - 2 is shown below. if another equation is graphed so that the system has one solution, which equation could that be? a) y = 2(x+1) b) y = 2(x-1) c) y = 2(x-2) d) y = -2(x+1) question 2) solve the inequality and then graph its solution. 1/5(x-2) -1 a) x -7 b) x -3 c) x -3 d) x 3

Step-by-step answer

The first question is D, because when graphed, intercepts with the slope of 3, the only with the solution.

The second question is C, because u can multiple the LHS and RHS to get x-2 is greater than -5. Add 5 to get x is greater than -3
