Park Jimin paid $125 to have his hair colored and cut. If he tips his hairdresser 15% of his bill, how much was the tip?

Virty [35]

Money paid by Park Jimin = $125

We need to find the tip , so,

→ 15% of the amount paid

→ $ 125 (15/100)

→ $ 18.75

Hence, the tip is of $ 18.75

Answer the following correctly

Answer:

$y = -\frac{10}{3}x - 23$

Step-by-step explanation:

Find slope (m) using of the line that passes through (-9, 7) and (-6, -3).

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-3 - 7}{-6 -(-9)} = \frac{-10}{3} = -\frac{10}{3}$

Find y-intercept (b) by substituting m = -10/3, x = -6, and y = -3 in y = mx + b.

Thus:

-3 = (-10/3)(-6) + b

-3 = 20 + b

Subtract 20 from each side

-23 = b

b = -23

substitute m = -10/3, and b = -23 in y = mx + b, to get the equation.

The equation of the line would be:

✅ $y = -\frac{10}{3}x + (-23)$

$y = -\frac{10}{3}x - 23$

What is the solution of log2 (3x-7) =3

Valentin [98]

Answer:

x = 5

Step-by-step explanation:

because the log is base 2 you can remove the log by raing 2 to the power of each side:

$2^{log2 (3x-7)} = 2^{3}$

the 2 and log2 cancel leaving:

$3x-7 = 2^{3}$

this means we can now solve through simple algebra:

$3x-7 = 8\\3x = 8 + 7\\3x = 15\\3x/3 =15/3\\x = 5$
