Briana is wrong. The 2 line cannot be parallel since their slopes are not the same. The slope of one line is 2 and the slope of the other is 2.5.
The other student is right. Just replace (9, 21.5) in both equations and it will satisfy both equation.
10x+3y=43
-9x-y=-20
From second equation,
y=-9x+20
Substitute third equation into first equation,
10x+3(-9x+20)=43
10x-27x+60=43
-17x=43-60
-17x=-17
x=1
y= -9+20= 11
Option B
12 bro it even says to follow the order of operations. If there is only addition and subtraction you just go from left to right. Same with if there is only multiplication and division.
Answer:
A circle is shown. Secants P N and L N intersect at point N outside of the circle. Secant P N intersects the circle at point Q and secant L N intersects the circle at point M. The length of P N is 32, the length of Q N is x, the length of L M is 22, and the length of M N is 14.
In the diagram, the length of the external portion of the secant segment PN is <u>X</u>
The length of the entire secant segment LN is <u>36</u>.
The value of x is <u>15.74</u>

Step-by-step explanation:
here's your solution
=> volume of cylinder = πr^2h
=> radius of cylinder = 12 unit
=> height of cylinder = 17 unit
=> volume of cylinder = 2448 π units^3
