8 0

Answer:

x>-4.5

Step-by-step explanation:

- 11x + 32.5 < 82

Subtract 32.5 from each side

- 11x + 32.5-32.5 < 82-32.5

- 11x < 49.5

Divide each side by -11. remembering to flip the inequality since we are dividing by a negative

-11x/-11 > 49.5/-11

x>-4.5

The circle given by : x^2 + y^2 - 6y - 12 = 0 can be written as:

deff fn [24]

Step-by-step explanation:

Given equation of circle is,

${x}^{2} + {y}^{2} - 6y - 12 = 0 \\ by \: compairing \: it \: with \: \\ {x}^{2} + {y}^{2} + 2gx + 2fy = 0 \: we \: get \\2 g = 0 \: or \: g = 0 \\ 2f= - 6 \\ or \: f= - 3 \\ c = - 12$

again the another form of circle is,

${x}^{2} + {(y - k)}^{2} = 21 \\ or \: {x}^{2} + {y}^{2} - 2ky + {k}^{2} - 21 = 0 \\ by \: compairing \:it \: with \: \\ {x}^{2} + {y}^{2} + 2gx + 2fy = 0 \: we \: get \\ g = 0 \\f = - k \\ c = {k}^{2} - 21$

now equating the values of f in both equations,

-k=-3

i.e. k=3

therefore k=3

The area of a rectangular raised garden bed for growing beets is given by the expression(3b)(3b-3). The length, l, of the mat is

mars1129 [50]

Answer:

C and D

Step-by-step explanation:

The area of a rectangular raised garden bed for growing beets is given by the expression $(3b)(3b-3).$

The area of the rectangle is

$A=\text{Width}\cdot \text{Length}$

Thus,

$\text{Width}=3b\\ \\\text{Length}=3b-3$

or

$\text{Width}=3b-3\\ \\\text{Length}=3b$

The length of the mat is greater than its width. Since

$3b>3b-3$

then

$\text{Width}=3b-3\\ \\\text{Length}=3b$

Options A and B are false, options C and D are true.
