X-5 < -2
add 5 to both sides
x < -7
so put a closed dot at -7 and draw a line towards the left side

OK, so basically it want you to write out the number line and the draw a circle on the number 3 and then draw a line that goes until the end of your number line which represents infinity, and have a arrow on the end of it.
it will look kinda like this.

<-------------------------------------3 make sure you color in a circle on the three. that will show that it is less than or greater to the three

Solve the system of equations. How many solutions foes the system have? Help pls :D

jenyasd209 [6]

Answer:

Infinitely Many Solutions

Step-by-step explanation:

Step-1: Re-write the equations into correct form.

=> 6x + 3y = 24

y = -2x + 8

=> 6x - 24 = -3y

-2x + 8 = y

Step-2: Multiply "-2x + 8 = y" by 3.

=> 6x - 24 = -3y

-6x + 24 = 3y

Step 3: Subtract or Add if needed

=> 0 = 0

Because we got a result 0 = 0, this means that the system has infinitely many solutions.

Hoped this helped.

Q10: Determine the eccentricity, the type of conic, and the directrix for r = 11/6-5cos theta.

Marta_Voda [28]

Answer:

Eccentricity = 5/6

Type of conic section; Ellipse

Directrix; x = -11/5

Step-by-step explanation:

The first step would be to write the polar equation of the conic section in standard form by multiplying the numerator and denominator by 1/6;

$r=\frac{\frac{11}{6} }{1-\frac{5}{6}cos theta }$

The polar equation of the conic section is now in standard form;

The eccentricity is given by the coefficient of cos theta in which case this would be the value 5/6. Therefore, the eccentricity of this conic section is 5/6.

The eccentricity is clearly between 0 and 1, implying that the conic section is an Ellipse.

Since the conic section is in standard form, the numerator is the product of eccentricity and the value of the directrix, that is;

e*d = 11/6

5/6*d = 11/6

d = 11/5

Since the denominator has a minus sign then the ellipse opens towards the right and thus the equation of its directrix is;

x = -11/5
