Simplify 7 log3 k + 6 log3 m − 9 log3 n
kaheart [24]
 The answer is log3 k to the seventh power m to the sixth power over n to the ninth power

a * logₓ(y) = logₓ(yᵃ)
7 log₃ (k) = log₃ (k⁷)
6 log₃ (m) = log₃ (m⁶)
9 log₃ (n) = log₃ (n⁹)

7 log₃ (k) + 6 log₃ (m) - 9 log₃ (n) = log₃ (k⁷) + log₃ (m⁶) - log₃ (n⁹)

logₓ(y) + logₓ(z) = logₓ(y * z)
log₃ (k⁷) + log₃ (m⁶) - log₃ (n⁹) = log₃ (k⁷ * m⁶) - log₃ (n⁹)

logₓ(y) - logₓ(z) = logₓ(y / z)
log₃ (k⁷ * m⁶) - log₃ (n⁹) =  log₃ (k⁷ * m⁶ / n⁹)

linda has $9 in her wallet. she buys a car for $1.17. she wants to buy some pens that cost 2.65 each. what is the maximum number
ch4aika [34]
1.17 + 2.65p = 9
2.65p = 9 - 1.17
2.65p = 7.83
p = 7.83/2.65
p = 2.95.......maximum number of pens Linda can buy is 2

What is the image of N for a 300° counterclockwise rotation about the center of the regular hexagon? Will give brainiest only if
OLEGan [10]

Answer:

H

Step-by-step explanation:

here, the question says that the given regular hexagon needs to be rotated counter clockwise 300°, considering the edges labels, each movement from one edge to other is 60° as 360/6 =60.

focus on N and move on anti clockwise.

When N rotates anti clockwise about center from original to position G, is 60°,

when N moves on anti clockwise about center from original to position A is 120°.

similarly, to X is 180°, to E is 240° and to H is 300°.

so, the new position of N when rotated anti clockwise about origin of the hexagon will be at H.

Find X when y= -2 <br> Thank you for your help and have a blessed day
Andreas93 [3]

Answer:

x = -5

Step-by-step explanation:

4x+y=2(x+3y)\\\\4x-2=2(x+3(-2))\\\\4x-2=2(x-6)\\\\4x-2=2x-12\\\\4x-2+2=2x-12+2\\\\4x=2x-10\\\\4x-2x=2x-2x-10\\\\2x=-10\\\\\frac{2x=-10}{2}\\\\\boxed{x=-5}

Hope this helps.
