Answer:

10/9

Step-by-step explanation:

This equation is in slope-intercept form, this is referring to the y-intercept. Slope-intercept is y=mx+b, where m is the slope and b is the y-intercept. Therefore, 10/9 is the intercept while -8 is the slope.

Write 169=13^2 in logarithmic form​
e-lub [12.9K]

Answer:

\log_{13}(169)=2

Step-by-step explanation:

The given exponential form is:

169=13^2

The base of the given expression on the right is 13 and the exponent is 2.

The number is 169.

In terms of logarithms, the base still remains the base and the exponent becomes the result of the logarithm of the number 169 to the given base 13.

\log_{13}(169)=2

For the graph, what is a reasonable constraint so that the function is at least 300?
blsea [12.9K]

Answer:

C) 0 ≤ x ≤ 25

Step-by-step explanation:

We are supposed to find a reasonable constraint so that the function is at least 300 i.e. the value of x at which f(x) is greater or equal to 300

A)x ≥ 0

Refer the graph

At x = 0

f(x)=300

On increasing the value of x , f(x) increases but at x = 12 it starts decreasing

So, x ≥ 0 can also have f(x)<300

So, Option A is wrong

B)−5 ≤ x ≤ 30

At x = -5

f(x) = 100

So, Option B is wrong since we require f(x) is greater or equal to 300

c)0 ≤ x ≤ 25

At x = 0

f(x)=300

At x = 12 , it starts decreasing

At x = 25

f(x)=300

So, The value of f(x) is at least 300 when 0 ≤ x ≤ 25

D)All real numbers

At x = 30

f(x)=0

But we require f(x) greater or equal to 300

Hence Option C is true

What is the slope of the line containing (-2, 5) and (4,-4)?
Pachacha [2.7K]

Answer:

Option C is correct.

Step-by-step explanation:

<h2>slope \:  =  \:  \frac{y2 - y1}{x2 - x1}</h2><h3>=  \frac{ - 4 - (5)}{4 - (2)}</h3><h3>=  \frac{ - 9}{4 + 2}</h3><h3>=  \frac{ - 9}{6}</h3><h3>= \frac{3( - 3)}{3 - 2}</h3><h3>=  -  \frac{3}{2}</h3><h3>Hope it is helpful....</h3>
