In the graph is shown: x-axis is the hours that student spend studying for the test and y-axis is a grade obtained by student. The best fit equation is y=3.75x+52.5.
If student spend 0 hours, then x=0 and y=3.75*0+52,5=52.5. It is that the student most likely earn <span>grade of 52.5 in the test. </span>
Answer:
x =
Step-by-step explanation:
=> 3+2(2x+8) = 1
=> 3+4x+16 = 1
=> 4x+19 = 1
=> 4x = 1-19
=> 4x = -18
<u><em>Dividing both sides by 4</em></u>
=> x =
=> x =
Answer:
The range is the difference between the highest and lowest number
Answer:
90+65=155-180=-25 and take out the -=25 thusAB=25 degrees
Step-by-step explanation:

Since we are solving for b, you need to get it by itself. So you would divide both sides by 3a. That would leave b= -7/3a.
Hope this helps!!
