Answer:

The function B has greater constant

Step-by-step explanation:

$m(b) = \frac{20 - 15}{1 - 2} = - 5 \\ y = - 5x + c \\ when \: y = 20 \: \: \: \: \: and \: x = 1 \\ 20 = - 5 \times 1 = c \\ c = 25$

A student solved z + (-0.72) = -2.5 for z using the

N76 [4]

Answer:

Mistake in step1

Step-by-step explanation:

<u>Given</u>

z + (-0.72) = -2.5

<u>Solving in steps</u>

1. ⇒ z + (-0.72) - (-0.72) = -2.5 - (-0.72)
2. ⇒ z = - (2.5 - 0.72)
3. ⇒ z = - 1.78

The student's mistake was adding (-0.72) instead of - (-0.72) or 0.72

Rewrite the expression as an equivalent ratio of logs using the indicated base.log17(52.875) to base 10.

s2008m [1.1K]

Answer:

$log_{17}52.875 = log_{10}52.875 : log_{10}17}$

Step-by-step explanation:

Given

$log_{17}(52.875)$

Required

Convert to base 10

To do this, we make use of the following logarithm laws;

$log_ba = \frac{log_{10}a}{log_{10}b}$

In the given parameters;

$a = 52.875$

$b = 17$

Substitute these values in $log_ba = \frac{log_{10}a}{log_{10}b}$

$log_{17}52.875 = \frac{log_{10}52.875}{log_{10}17}$

Represent as a ratio

$log_{17}52.875 = log_{10}52.875 : log_{10}17}$

Hence;

$log_{17}(52.875)$ is represented as $log_{17}52.875 = log_{10}52.875 : log_{10}17}$
