If log subscript 2 left parenthesis 3 x minus 2 right parenthesis equals 4, then what is the value of x?
elena-14-01-66 [18.8K]

Answer:

x = 6

See image.

Step-by-step explanation:

Logarithms are just another way to write exponents. The base on the logarithm that is the small font subscript IS the base (normal font/on the line) of an exponential equation. The "answer" in the logarithmic equation is the exponent (small font/superscript) .It is just a triple shuffle. When the logarithmic equation cant be worked on to solve it, CHANGE IT to exponential form. See image.

Out of 150 students at JHS 190, 48 had Calamari for lunch. What percent had Calamari for lunch?
kirill [66]

Answer: 32%

Step-by-step explanation:

The percent that had Calamari for lunch would be calculated as:

= Number of students that had Calamari / Total students at JHS 190 × 100

= 48/150 × 100

As shown in the image below, triangle ABC is reflected onto its image. А B с С" A Which of the following lines represents the li
dybincka [34]

Answer:

Line of reflection will be y = -2

Step-by-step explanation:

From the picture attached,

Triangle ABC has been reflected over an unknown line so that the triangle ABC will overlap triangle A'B'C'.

To find the line of reflection,

Coordinates of point C → (7, 0)

Coordinates of point C' → (7, -4)

Line of reflection = line passing through midpoint of the line joining C and C'

Midpoint of the line joining points C and C' = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})

                                                                        = (\frac{7+7}{2},\frac{0-4}{2})

                                                                        = (7, -2)

Therefore, line of reflection is y = -2.
