1 answer:

3 0

$\log_2 (\log_5( \log_3x)) = 0\\
D:x>0 \wedge \log_3x>0 \wedge \log_5(\log_3x)>0\\
D:x>0\wedge x>1 \wedge\log_3x>1\\
D:x>1 \wedge x>3\\
D:x>3\\
\log_5(\log_3x)=1\\
\log_3x=5\\
x=3^5\\
x=243$

Answer:

$q\le \:12$

Step-by-step explanation:

<u>Solving</u>

$\mathrm{Switch\:sides}$ (Not a required step)

$q+3\le \:15$

$\mathrm{Subtract\:}3\mathrm{\:from\:both\:sides}$

$q+3-3\le \:15-3\\=q\le \:12$

Answer:

Graph A

Step-by-step explanation:

$y = {x}^{2} - 6x - 7 \\ plug \: y = 0 \\ {x}^{2} - 6x - 7 = 0 \\ {x}^{2} - 6x + 9 = 7 + 9 \\ (x - 3)^{2} = 16 \\ (x - 3) = \pm 4 \\ x = 4 + 3 \: or \: x = - 4 + 3 \\ x = 7 \: or \: x = - 1$

Its mean graph should intersect x axis at x = 7 and x = - 1. This everything is satisfied by graph A.

What is the soulution of -(-5-6x) = 4(5x+3)?

Fynjy0 [20]

You have to distribute the parentheses first. Since there is a negative sign in front of the parentheses, it counts as a negative 1. After you distribute you should get: -5+6x=20x+12, but that is not your final answer. After you add like terms: 17x=-17. Divide 17 on both sides: x=-1. X=-1 is your final answer.

Eddi Din [679]

Answer:

Class 8 has 27 and class 7 has 40

Step-by-step explanation:

8th (r) class has 13 fewer than 7th (x).
x -13 = r

Total for both classes = 67

r + x - 13 = 67
r + x = 80

80 divided by two = 40 (per class)

40 - 13 = 27
