Answer:
x = 4
Explanation:
3x - 4y = 36
5x + 2y = 8 ( multiply all by two )
3x - 4y = 36
10x + 4y = 16
13x = 52
Divide by 13
x = 4 hope this helps
Answer:
Base:3
Height:5
Area= 15
Step-by-step explanation:
Formula=BxH
3x5=15
Y =3x+13---------#
-4x+3y=19-------*
subsititute value of y in equation *
-4x+3(3x+13)=19
-4x+9x+39=19
5x=-20
x=-20/5
x= -4
The formula for the volume of a cone is:
V= (1/3) x
x
x height
Since this is a quadratic equation, if the radius is multiplied by 3, then the volume is multiplied by its square, which is 9.
Hope this helps!
