What is the result of the first step when simplifying 13-4(x-5)

1 answer:

8 0

I don't really get this question but simply put, if you are in college syntax matters very much. (13-4) = 9 *(x-5) = 9x-45.. although in this case. since there isn't a bracket around 13-4. you'd multiply by the -4 first, giving you, 4x-20+30 =4x-10

What is the average rate of change for this function for the interval from x=3 to x=5?

SSSSS [86.1K]

Answer:

A. 49

Step-by-step explanation:

The average rate of change for the interval ranging from x = 3 to x = 5 for the given function represented in the table above can be calculated using:

$Average rate of change = \frac{f(x2) - f(x1)}{x2 - x1}$

x2 = 5

x1 = 3

f(x2) = f(5) = 125

f(x1) = f(3) = 27

Thus,

$Average rate of change = \frac{125 - 27}{5 - 3}$

$= \frac{98}{2}$

Average rate of change = 49

Average rate of change of the given table values representing an exponential function is A. 49.

What is the slope of a linear that is perpendicular to the line y=-1/2x+5?

Vlada [557]

Step-by-step explanation:

Equation of given line is:

$y = - \frac{1}{2} x + 5 \\ \\ equating \: it \: with \: y =m_1x + c \\ we \: find \: \\ m_1 = - \frac{1}{2} \\ let \: m_2 \: be \: the \: slope \: of \: required \: line \\ \\ \therefore \: m_1 \times m_2 = - 1( \because \: lines \: are \: \perp) \\ \\ \therefore \: - \frac{1}{2} \times m_2 = - 1\\ \\ \therefore \: m_2 = 2 \\$

Thus, the slope of required line is 2.

HELP ME PLS I NEED TO ACE THIS TEST!

The rate of change is -$45, and it represents the amount of money withdrawn each month.

We can find the rate of change by finding the change in y/change in x:

145-190/1-0 = -45/1 = -45

This would be the amount of money he withdraws from his account each month.
