Circle has a radius of 4 and the center is (-4,-8) what is the equation of the circle if I double the radius

wariber [46]

Answer:

(x +4)^2 +(y +8)^2 = 64

Step-by-step explanation:

The equation of a circle with center (h, k) and radius r is ...

(x -h)^2 +(y -k)^2 = r^2

The circle centered at (h, k) = (-4, -8) with radius 8 has equation ...

(x +4)^2 +(y +8)^2 = 64

0.7 (3s + 4)-1.1s = 7.9

vichka [17]

Answer:

s = 5.1

Step-by-step explanation:

$0.7 (3s + 4)-1.1s = 7.9\\$

Multiply both sides of the equation by 10

$0.7\left(3s+4\right)\cdot \:10-1.1s\cdot \:10=7.9\cdot \:10\\\\= 7\left(3s+4\right)-11s=79\\$

Expand

$\mathrm{Expand\:}7\left(3s+4\right)-11s:\\\quad 10s+28$

Subtract 28 from both sides

$10s+28-28=79-28$

Simplify

$10s=51$

Divide both sides of the equation by 10

$\frac{10s}{10}=\frac{51}{10}$

Simplify

$s=\frac{51}{10}\\\\Decimal = 5.1$

Find the equation of the graph in function notation. Name your function "f" and use x as your variable.

kumpel [21]

Answer:

$f(x)=\frac{1}{2}x-1$

Step-by-step explanation:

The equation of the graph can be obtained using the formula:

$\frac{x}{x-intercept}+\frac{y}{y-intercept}=1$

From the graph, the y-intercept is -1 and the x-intercept is 2

We substitute these values to get:

$\frac{x}{2}+\frac{y}{-1}=1$

$\frac{x}{2}-y=1$

This implies that;

$\frac{x}{2}-1=y$

$y=\frac{1}{2}x-1$

The function notation is

$f(x)=\frac{1}{2}x-1$
