Solve x/5 - 1=7? help please !!

xxTIMURxx [149]

First, add 1 on both sides of the equation to begin to isolate x

x/5 = 8

Now, to isolate x, multiply both sides of the equation by 5/1

$\frac{x}{5}$ · $\frac{5}{1}$ = $\frac{5x}{5}$ = x

x= 7 · 5/1 = 7 · 5 = 35

x = 35

write the standard form of the equation of the circle with the given center and radius (6,4), r= square root of 7

REY [17]

The standard form of the equation of a circle is $(x-6)^{2}+(y-4)^{2}=7$ .

Solution:

Center of the circle = (6, 4)

Radius of the circle = $\sqrt{7}$

<u>To find the equation of the circle:</u>

General formula for the equation of a circle

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

where (h, k) is the center of the circle and r is the radius of the circle.

Here, h = 6, k = 4 and r = $\sqrt{7}$

$(x-6)^{2}+(y-4)^{2}=(\sqrt{7}) ^{2}$

$(x-6)^{2}+(y-4)^{2}=7$

Hence the standard form of the equation of a circle is $(x-6)^{2}+(y-4)^{2}=7$ .
