Answer:
it has one solution
Step-by-step explanation:
1.y=x-3
2. 3y-3x sub x-3 in place of y therefore
it can also be written as 3x-3x-9=9
if you add 9 to both sides 3x-3x-9+9=-9+9
0+0=0
Evaluate them
A.
f(5), x>1 so square it, f(5)=25
A is wrong
B.f(2), x>1 so square it, f(5)=4
B is correct
C. f(1), x=1 so the result is 5, f(1)=5
C is correct
D. f(-2), x<1 so double it, f(-2)=-4
D is wrong
answers are B and C
On the left side of the equation, we have 3x or 3 * x. But in algebra, we usually just do 3x.
We need to find a value for x that when multiplied by -3 equals to -216.
We can find the value for x by dividing both sides by the coefficient of 3x. Which is 3.
3x / 3 = -216 / 3
x = -72
So, x is equal to -72.
