Area of a circle is:

A = pi(r^2)
A = 3.14(8^2)
A = 3.14(64)
A = 200.96

hope this helps :)

F(x)=lx+4l+3 how do u do it

dybincka [34]

Answer:

implifying

f(x) = lx + 4l + -3

Multiply f * x

fx = lx + 4l + -3

Reorder the terms:

fx = -3 + 4l + lx

Solving

fx = -3 + 4l + lx

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Divide each side by 'x'.

f = -3x-1 + 4lx-1 + l

Simplifying

f = -3x-1 + 4lx-1 + l

Reorder the terms:

f = l + 4lx-1 + -3x-1

Write an equation of the line in slope-intercept form: y-intercept of 2, x-intercept of 4

zvonat [6]

Answer:

$\sf y=-\dfrac12x+2$

Step-by-step explanation:

y-intercept is when x = 0, so (0, 2)

x-intercept is when y = 0, so (4, 0)

$\sf slope=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{0-2}{4-0}=-\dfrac12$

Slope-intercept form of linear equation: $\sf y=mx+b$

(where m is the slope and b is the y-intercept)

Given:

$\sf m=-\dfrac12$
b = 2

$\sf \implies y=-\dfrac12x+2$
