Hi!
Step-by-step explanation:
<u><em>Slope is -3</em></u>
<u><em>Final answer is -3.</em></u>
Hope this helps!

Have a nice day! :)

<span>3x^2 = 7x - 3
Rearranging,
</span><span>3x^2 - 7x + 3 = 0
</span>Using quadratic formula :
x= [7 + sqrt (49 - 36)]/6
x= [7 + sqrt 13]
or
x= [7 - sqrt (49 - 36)]/6
x= [7 - sqrt 13]/6
<span>d. x - 7 plus or minus the square root of 13 divided by 6</span>
X = number of MC questions
y = number of T/F questions
x+y=24
2x+6y=100
x=24-y
2(24-y)+6y=100
48+4y=100
y=13
x=24-13=11
We will use sine for this. Pls see the below explanation. Hope it helps but I’m not entirely sure as I do not know if you can choose any trigonometry law or must use a specific law. Good luck!
Answer:x= 36 y= 67 and z=77
Step-by-step explanation: we have to write the equations from the data give in the exercise, this means :
First of all, x,y and z correspònd to the first, second and third angles, respectively.
The sum of the measures of the angles of a triangle is 180
can be written as x+y+z=180
The sum of the measures of the second and third angles is four times the measure of the first angle.
It can be written by: x+y=4z
The third angle is 10 more than the second
It can be written as z=y+10
By solving the equations systems the above values can be determined.
x+y+z=180
x+y=4z
z=y+10
