Answer: The number would be 18
Step-by-step explanation:
18/2=9 9-3=6 6*3=18
Answer:
coefficient of x^2 is -4
and degree of polynomial is 3
Answer:
The least score the student can get is 71 to get an overall B average at the end of the year.
Step-by-step explanation:
Let the score she needs to get be = x
We now have to take the mean of all the five subjects <em>(including x)</em> and equate it to the least score she can have to get a B grade.
Let us take the least score the student needs to get a B grade to be 85
Mean of all 5 scores =




The least score the student can get is 71 to get an overall B average at the end of the year.
Here's the slope form; (y2- y1) / (x2 - x1)
All you have to do now is just plug in the number into the formula.
(6 - -4) / (6 - 1) = 10/5
Then divide, and the answer is D. 2.
Answer:
Step-by-step explanation:
The two x angles on the right are supplementary which means they add up to 180 degrees
5x + 12 + 7x - 24 = 180
12x - 12 = 180
12x = 192
x = 192/12
x = 18
5x + 12 and y are corresponding angles and are therefore equal
5(18) + 12 = 90 + 12 = 102
Therefore y = 102
