−42x − 6y > 24

Because we have ">", it could be one of the top graphs.

−42x − 6y > 24 ----> - 7x -y > 4, y < -7x -4

Answer is top right (B).

Answer:

Graph on the top right will be the answer.

Step-by-step explanation:

The given inequality is -42x - 6y > 24

We can rewrite the given equation in the simplified form

-42x - 6y > 24

42x + 6y < -24

7x + y < -4 [divide by 6 on both the sides]

y < -7x - 4

Since the given line has the sign of less than (no sign of equality), the line will be in the dotted form.

Since inequality sign represents less than, shaded area will be on the left side of the dotted line.

Therefore, Graph on the top right will be the answer.

Find the radius of a circle with a circumference of 96 feeer

Gnesinka [82]

The formula for circumference is C = 2πr.

The question gives you the circumference (C in the formula), and you need to find the radius (r in the formula). Begin by isolating r in the circumference formula.

C = 2πr
C/2π = r
r = C/2π

Now you can plug 96 for C and solve to find r.

r = C/2π
r = 96/2π
r ≈ 96/6.28
r ≈ 15.29

Answer:
The radius of a circle with a circumference of 96 feet is approximately 15.29 feet.

Answer:

$x= \frac{ - 11 + \sqrt{205} }{6} \: \: \: \: \: or \: \: \: \: \\x = \frac{ - 11 - \sqrt{205} }{6}$

Step-by-step explanation:

$- 3x {}^{2} - 11x + 7 = 0 \\ 3x {}^{2} + 11x - 7 = 0$

here,

$a = 3 \\ b = 11 \\ c = - 7$

now,

$D = b {}^{2} - 4ac \\ = (11) {}^{2} - 4(3)( - 7) \\ = 121 + 84 \\ = 205 > 0 \\$

so,

$x = \frac{ - b + - \sqrt{b {}^{2} - 4ac} }{2a} \\ \\ = \frac{ - 11 + - \sqrt{205} }{2(3)} \\ = \frac{ - 11 + - \sqrt{205} }{6} \\ \\ = \frac{ - 11 + \sqrt{205} }{6} \: \: \: \: \: or \: \: \: \: = \frac{ - 11 - \sqrt{205} }{6}$
