No, I dont believe its the same thing because I remember doimg those equations in high school and they were different

PLZ HELP!!! 20 POINTS!!!<br><br> 1. Solve the system of equations by graphing: x + y = 3

sveticcg [70]

First you need to fix the equation in order to graph.
x + y = 3
Subtract x from both sides.
y = -1x + 3
Now graph.
(Whenever there is a variable by itself there is always a 1 in front of it.)

Suppose the weather forecast calls for a 60% chance of rain each day for the next 3 days. What is the probability that it will N

erastovalidia [21]

Answer:

Probability that it'll not rain during the next three days = 0.064

Step-by-step explanation:

Given

Let:

P(R) represent the probability that it'll rain each day

P(R') represent the probability that it'll not

$P(R) = 60\%$

Required

Probability that it'll not rain during the next three days

From concept of probability;

$P(R) + P(R') = 1$

Substitute 60% for P(R)

$60\% + P(R') = 1$

Subtract 60% from both sides

$60\% - 60\% + P(R') = 1 - 60\%$

$P(R') = 1 - 60\%$

Convert % to decimal

$P(R') = 1 - 0.6$

$P(R') = 0.4$

The probability that it'll not rain during the next 3 days is:

$P(R') * P(R') * P(R')$

$P(R') * P(R') * P(R') =0.4 * 0.4 * 0.4$

$P(R') * P(R') * P(R') = 0.064$

Let g(x) = log7 (x),<br> find g ¹(0)

klasskru [66]

Step-by-step explanation:

The derivative of log is

$\frac{d}{dx} ( log_{a}(x) ) = \frac{1}{x \: ln(a) }$

You can easily derive this using the Change of base rule, and natural log rules

$log_{a}(x) = \frac{ log_{e}(x) }{ log_{e}(a) } = \frac{ ln(x) }{ ln(a) }$

Next, we differentiate with respect to x.

$\frac{d}{dx} \frac{ ln(x) }{ ln(a) } = \frac{1}{ ln(a) } \times \frac{d}{dx} ln(x)$

$= \frac{1}{x ln(a) }$

So back to the topic at hand,.

a=7, so we get

$\frac{1}{x ln(7) }$

We plug in 0, we would get undefined
