Slope intercept form is y=mx+b
m(slope)=1/2
(x,y)—->(-8,-4) so x=-8 and y=-4 substitute and solve for b
-4=1/2(-8)+b
-4=-4+b
+4=+4
0=b
Answer:
Step-by-step explanation:
Hi there,
To get started, recall the logarithm rules. For this question, we can use the log rule specifically when subtracting two log functions that have the same base:
![log_b\alpha -log_b\beta =log_b[\frac{\alpha }{\beta } ]](https://tex.z-dn.net/?f=log_b%5Calpha%20-log_b%5Cbeta%20%3Dlog_b%5B%5Cfrac%7B%5Calpha%20%7D%7B%5Cbeta%20%7D%20%5D)
In this prompt, our base is 4, so b in the above formula. Using this formula, we can find the missing <u><em>argument</em></u> (the number inside of the log, what we are asked to solve for):
![log_49-log_411=log_4[\frac{9}{11} ]\\](https://tex.z-dn.net/?f=log_49-log_411%3Dlog_4%5B%5Cfrac%7B9%7D%7B11%7D%20%5D%5C%5C)
hence the missing argument is 9/11
At this point, there is no easier say to simplify, unless you wish to approximate 9/11 as 0.818. If you wish to solve for the exponent, you will have to use common log or natural log to do so.

Answer:

on that equation there is the point (-5 , 7)
Answer:
<u>The correct answer is 5/24 or 0.21</u>
Step-by-step explanation:
1. Let's review all the information given to answer the question correctly:
Science class in seventh grade = 4 girls and 4 boys
Science class in eighth grade = 5 girls and 7 boys
2. What is the probability that both students selected for the competition are girls, a seventh grader and an eighth grader?
These are independent events, therefore:
Probability of two independent events = Probability of A * Probability of B
Probability of both students selected for the competition are girls = 4/8 * 5/12
Probability of both students selected for the competition are girls = 20/96 = 5/24
<u>The correct answer is 5/24 or 0.21</u>
