16x^2+9=5
- 9 -9
16x^2= -4
16/-4 =
-4
Answer:
here's the steps
Step-by-step explanation:
first of the numbers inside the [ ] is always positive.Now since the 3 is outside the [ ] you use it like a tool and don't change it, so nothing happen to it.since ^3 is missing a base (variable, cannot remember exact name) but is not missing ^3, which make them alike enough to multiply because 3 is outside of () nut the ^3 will stay the same (don't know why but that's how math works)
46 percent as a decimal is 0.46
b-0.46b=p
b is original price
p is price after markdown
Answer:
Step-by-step explanation:
perpendicular is 90 degrees or inverse slope of that point
y = -1/4x -1
so the inverse slope of -1/4 is 4
now the other equation is
y = 4x - 1
So the two equations are
y = -1/4x -1
y = 4x - 1
double x + 3= 2x + 6. double four is 8. 8 * 2x + 6 = 16x + 48
