Answer:
y= -5x/-4 - 3
Step-by-step explanation:
The first thing you need to do is write down the problem 5x-4y=12.
You will then want to solve as shown below:
5x-4y=12
-4y=-5x+12 you want to isolate the y value
-4y/-4=-5x/-4+12/-4 you want to divide everything by negative 4
y= -5x/-4 - 3 you wan to clean your eqution up

uhmm...help please :< i'll give brainliest to whoever answers all three
1. 57 is the constant rate of change
2. The ratio for Ms. Bojorquez is 32:28 which simplified is 8:7. The ratio for Ms. William is 104:98 which simplified is 52:49. So they are not equivalent ratios.
3. No, it will take almost 10 minutes.
Hope this helps!!

Find all roots of the polynomial function f(x) = 2x^4-x^3-13x^2+5x+15
Answer:
Roots are : 1, -7 and -7
Step-by-step explanation:
When we put x = -1 in F(x) it is equal to 0
Thus, (x + 1) is factor of given function.
When we divide F(x) by (x + 1) it gives the value (x² - 6x - 7)
factorizing the work x² - 6x - 7 by middle term splitting.
> x² - 6x - 7 = x² - 7x + x - 7
> x(x - 7) + 1(x - 7)
> (x + 1) (x - 7)
then, x³ - 5x² - 13x - 7 = (x + 1)(x + 1)(x - 7)
x = -1, -1, 7 the factor.

Step-by-step explanation:
there are 6 boys and 5 girls in the debate class. kids are being selected to go present their work without getting opt-out where is the probability that a boy will be selected to present twice?
Answer:
30%?
Step-by-step explanation:
6 boys, 5 girls
first selection is a 6/11 chance it's a boy.
second seletion is a 6/11 chance it's a boy.
6/11 times 6/11 is... 0.2975 or about a 30% chance ( i think)
Just multiply the probability of the first event by the second. For example, if the probability of event A is 2/9 and the probability of event B is 3/9 then the probability of both events happening at the same time is (2/9)*(3/9) = 6/81 = 2/27.

Use the given line of best fit to approximate the rate of change relative to the scatter plot below.
A. 1/20 errors per word translated
B. 1/5 errors per word translated
C. 1/10 errors per word translated
D. 3/20 errors per word translated
Answer:
C. 1/10 errors per word translated
Step-by-step explanation:
According to this graph, we can see that every 100 words-translated, there are about 10 errors (red line). The red line continues at this slope/ratio, and so it would be 10/100 or 1/10 simplified.
The rate of change relative to the scatter plot below will be 1/10 errors per word translated. Option C is correct.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
For the given condition, we have to find the rate of change relative to the scatters plot below.
The given graph is in between the total error and the translation error. This graph shows that there are around 10 translation mistakes for every 100 words (red line). Given that the red line continues at this slope and ratio, it would be expressed as 10/100 or 1/10.
Thus, the rate of change relative to the scatter plot below will be 1/10 errors per word translated. Option C is correct.

The average cost of Purell in 2019 was $8.99 for a bottle. In 2020, the cost of Purell on Amazon jumped to $58.99. What is the percent change? Round to the nearest tenth of a percent.
Answer:
556.2% change
Step-by-step explanation:
Percentage change = (p2-p1)/p1 * 100%
= (58.99 - 8.99) / 8.99 * 100%
= 556.2% change

A because 1 is 1/4 of 4C because 3 is 1/4 of 12and D because 5 is 1/4 of 20Answer:
I belive a, c, and d.
Step-by-step explanation:
the proportionality is 1/4. these are the only letters that are like that. basically for a, 1×4=4 so that's correct. for c, 3×4=12 so thats correct, and d, 5×4=20 so that's correct. the other answers dont work, so only these are the correct answers.

George is 31 years older than Leo who is 15 years younger than Carol. In how many years will Carol be the same age as George is now?
Answer:
16 years
Step-by-step explanation:
Break the problem down:
George = 31 + Leo
Leo = Carol - 15
Carol = ?
The problem is asking for the number of years it will take for Carol to be George's current age.
Leo is 15 years younger than Carol which means Carol is 15 years older than Leo.
George is 31 years older than Leo. Carol is older than Leo by 15 years.
This means we have to find the difference between 31 and 15.
31 - 15 = 16
Since the difference between George and Carol's age is 16 years, it will take Carol 16 years to be the same age as George is now.
