Answer:
135 is the correct answer
Step-by-step explanation:
6x^2-3x
substitution
x=5
6* (5*5) -3*5
6*25-3*5
150-15= 135
20% of 59.95 is 47.96 the 7.5% tax makes it $51.55 witch is the answer
Answer:
0,3,4,-11
Step-by-step explanation:
Answer:
X=0
Step-by-step explanation:
Frst we want to check is it symmetry function?
F(-x)=f(x)?
We know that f(x)=x^2+0x-4=x^2-4.
What about f(-x)? F(-x)=(-x)^2-4=x^2-4, so we can conclud that f(-x)=f(x), the summetry!
Intesections with x is in the -2 and 2, so the middle is x=0.
1. (1/3) * (3/5) = 3/15
2. 3 1/3
3. So 3 1/3 * 2 1/4 = 6 1/2 C
