Is (0,0) a solution to this system y> x2+x-4 y <x2+2x+1

Aliun [14]

Answer:

Yes, the ordered pair (0,0) is a solution of the system

Step-by-step explanation:

we have

$y\geq x^{2}+x-4$ ----> inequality A

$y < x^{2} +2x+1$ ----> inequality B

we know that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities

Verify

For x=0,y=0

Inequality A

$0\geq (0)^{2}+0-4$

$0\geq -4$ ----> is true

The ordered pair satisfy inequality A

Inequality B

$0 < (0)^{2} +2(0)+1$

$0 < 1$ ----> is true

The ordered pair satisfy inequality B

therefore

The ordered pair (0,0) is a solution of the system

Find the value of x.

KengaRu [80]

Answer:

100

Step-by-step explanation:

The two angles form a straight line which is 180 degrees

5+x +75 = 180

Combine like terms

x+80 = 180

Subtract 80 from each side

x +80-80=180-80

x = 100

What is the value of X ? 4/5×-1/10 equals 310

Romashka-Z-Leto [24]

Answer:

387.625

Step-by-step explanation:

I'm not completely sure what that last number is supposed to be but if it is $\frac{4}{5}x -\frac{1}{10} =310$ , then the answer above is correct.

First, you create common denominators:

$\frac{8}{10}x -\frac{1}{10} =310$

Then you can get rid of the denominator by multiplying both sides by 10:

$8x -1 =3100$

Then add one to both sides to isolate x:

$8x = 3101$

Lastly, divide by 8:

$x = 387.625$
