Answer:

<h2>x = 5</h2>

Step-by-step explanation:

$-4(1-2x)-1=7x\qquad\text{use the distributive property}\ a(b+c)=ab+ac\\\\(-4)(1)+(-4)(-2x)-1=7x\\\\-4+8x-1=7x\qquad\text{combine like terms}\\\\8x+(-4-1)=7x\\\\8x-5=7x\qquad\text{add 5 to both sides}\\\\8x-5+5=7x+5\\\\8x=7x+5\qquad\text{subtract}\ 7x\ \text{from both sides}\\\\8x-7x=7x-7x+5\\\\x=5$

What is the equation of a circle whose center is begin ordered pair negative 4 comma 6 end ordered pair and whose radius is 9 cm

solong [7]

Answer:

$(x+4)^2+(y-6)^2=81$

Step-by-step explanation:

We want to find equation of a circle with center (-4,6) and radius 9cm.

The equation of a circle with center (h,k) and radius $r$ units is given by;

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

We substitute the radius and the center to obtain;

$(x+4)^2+(y-6)^2=9^2$

The required equation is:

$(x+4)^2+(y-6)^2=81$
