The roots (Zeros) are -9 and -5. The greater root is -5.
Answer:
C. f(x)= 0.5(3ˣ)
Step-by-step explanation:
C. f(x)= 0.5(3ˣ) is the function as per table
I hope this helps you
1)
y=6
x^2+6^2=25
x^2=25-36
x^2= -9
x^2=i^2.9
x=3i there's no real solution
2)
x^2+(2x-2)^2=25
x^2+4x^2-8x+4=25
5x^2-8x=21
5x^2-8x-21=0
5x +7
x -3
(5x+7)(x-3)=0
x= -7/5
x=3
Answer:
rearrange the equation to y=mx+c and simplify it
to get
2x+3y=27
3y= -2x+27
y= (-2/3)x+ 9
perpendicular line - flip the gradient and add a negative sign
so -2/3 become 3/2 (the negative sign is cancelled, since it was already negative)
y=(3/2)x+c
y=1.5x+c
to find the intercept
input the x and y values
3= 1.5*-2+c
3=-3+C
6=c
therefor y=1.5x+6
