If f(3)=2x^3 -2 , what is the value of f(2)

Mathematics
1 answer:
iris [78.8K]3 years ago
5 0

I'm not sure about this but will give it a try:

Let f(n) = 2xⁿ - 2

Then f(3) = 2x³ - 2

So, f(2) = 2x² - 2

Find the solution of this system of equations 5x - 6y =-90 -10x - 6y =-90
ExtremeBDS [4]

5x - 6y = -90

-10 x - 6y = -90

Subtracting,

15x = 0

x = 0

y = -90/(-6) = 15

Answer: x=0, y=15

Whats the abswer to 1/2x+3/4=1
g100num [7]
<em>*Because of BODMAS, 1/2x=x/2.</em>

1/2x+3/4=1

1/2x+3/4=4/4

1/2x=4/4-3/4

1/2x=1/4

x/2=1/4

x=2/4

x=1/2

write an equation in slop-intercept form for a line that is perpendicular to the line y= -5x-3 and has a y-intercept of 6.
jenyasd209 [6]

Answer:

The equation of the line would be y = 1/5x + 6

Step-by-step explanation:

First, to find the slope of a perpendicular line, you need to find the opposite and reciprocal of the original slope. Since the original is -5, we first change the sign (which makes it just 5). Now we take that 5 and flip it to get 1/5.

Now that we have the slope as 1/5, we can use that and the intercept in slope-intercept form to get the equation.

y = mx + b

y = 1/5x + 6
