Answer: x = -8 ; y = -6
Step-by-step explanation:
1*x-2*y=4
1*x = 4 + 2*y
x = 4 + 2*y
Now you replace the value of x on the following equation:
-1*x+10*y=8
-1*(4 + 2*y) = 8
-4 - 2*y = 8
-2*y = 8+4
-2*y = 12
y = -12/2
y = -6
You replace the value of y in the previous equation:
x = 4 + 2*y
x = 4 + 2*(-6)
x = 4 - 12
x = -8
Answer:12
Step-by-step explanation:
Your goal with variables should always be to isolate them.
so the first step is to subtract the 4
3x^2+4=436
-4= -4
3x^2=432
The next step to isolate the variable x is to get rid of the 3. To get rid of the 3 you have to divide both sides by 3 since it is the opposite of multiplying.
3x^2=432
/3. =/3
x^2=144
the last step to isolate the x is to do the opposite of what an exponent is, which is to find the square root. So when you square the x^2, the exponent cancels out.
square root of x^2=x
square root of 144=12
x=12

You would use the volume of a cone formula ((1/3)(pi)(r^2)h) so it would be (1/3)(pi)(7^2)(24). That simplified to 392(pi) units^3. So the answer is c
