Answer:
150 + 3x = 369 X= 73
Step-by-step explanation:
X is the amount of days
So 150 minus 369 would be 219
Then take 219/3 and that would mean X equals 73
The weighted mean if the quizzes each count for 20% and the final exam counts for 40% of the final grade rounded to one decimal place is <u>18.8</u>
Mean is the average set of numbers.
Given the Elaine quiz grades to be 90, 83 and 64
40% of the final grade will be expressed as:
20% of 90 = 18
20% of 83 = 16.6
20% of 64 = 12.8
If the quiz count for 40% of the final grade, then her final grade will be:
40% of 69 = 27.6
Take the weighted mean
Mean = Sum of scores/Sample size
Mean = (18+16.6+12.8+27.6)/4
Mean = 75/5
Mean = 18.75
Hence the weighted mean if the quizzes each count for 20% and the final exam counts for 40% of the final grade rounded to one decimal place is 18.8

Answer: Option b.
Step-by-step explanation:
1. You have the following parent function given in the problem above:
f(x)=x³ (This is the simplest form. We need to translate it 3 units left and 2 units down)
2. If you take the parent function and make y=f(x+3), then you have:
(The function is shifted 3 units left on the x-axis).
3. Then you if you make y=f(x+3)-2, as following, you obtain:
(The function is shifted 2 units down on the y-axis).
4. Therefore, that is how you obtain the final function.
The answer is the graph shown in the option b.
when you solve an inequality the result is an interval when you solve an equation is a number or set ex x^2=25 x=-+5 the result is finite numbers
when you multimply an equation the sign inverses but when you solve an equation there is nothing to change
similiarities
you can add and subtract numbers from both sides
diving and multypling the equation or inequation by a positive numeber as i said in the beggining by multypling or dividing with a negative number the equation s sign inverses ex >= becomes <=
