Step-by-step explanation:

4.5x-2.3=6.7 (add 2.3 so no number in the equation)

6.7+2.3 is 9

4.5x=9 (divide by 4.5 as it's 9 is divisible by 4.5

9/4.5 is 2

X=2

put it back into the equation

4.5*2 is 9

9-2.3 is 6.7

Therefore X=2

Answer:

x = 2

Step-by-step explanation:

Add 2.3 to both sides. We get:

4.5x = 6.7 + 2.3 = 9

If 4.5x = 9, then x = 2

Answer:

$(x-5)^2+(y+4)^2=100$

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The distance between the center and any point that lie on the circle is equal to the radius

we have the points

(5,-4) and (-3,2)

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute the values

$r=\sqrt{(2+4)^{2}+(-3-5)^{2}}$

$r=\sqrt{(6)^{2}+(-8)^{2}}$

$r=\sqrt{100}\ units$

$r=10\ units$

step 2

Find the equation of the circle

we know that

The equation of a circle in standard form is equal to

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

where

(h,k) is the center

r is the radius

we have

$(h,k)=(5,-4)\\r=10\ units$

substitute

$(x-5)^2+(y+4)^2=10^2$

$(x-5)^2+(y+4)^2=100$
