Answer:

{(x  + 6)}^{2}  +  {(y - 2)}^{2}=10

Step-by-step explanation:

The equation of a circle with center (a,b) and radius r, is

{(x - a)}^{2}  +  {(y - b)}^{2}  =  {r}^{2}

From the question, the center of the circle is located at (-6,2) and the radius is

r =  \sqrt{10}

We substitute the center and radius to get:

{(x -  - 6)}^{2}  +  {(y - 2)}^{2}  =  {( \sqrt{10} })^{2}

Simplify to obtain:

{(x  + 6)}^{2}  +  {(y - 2)}^{2}=10

Answer:

x = 14.13ft

Step-by-step explanation:

Given

See attachment for illustration

Required

Find x

To do this, we apply Pythagoras theorem.

From the attachment, the length of the hypotenuse is 16.7ft

While the length of the opposite/adjacent is 8.9ft

Length x is calculated using:

16.7^2 = 8.9^2 + x^2

x^2 = 16.7^2 - 8.9^2

x^2 = 199.68

Take square roots

x = \sqrt{199.68

x = 14.13ft

Solve the linear equation by using substitution X-y=-4 3x-y=-10
svetoff [14.1K]

Answer:

(-3, 1)

Step-by-step explanation:

x-y=-4

3x-y=-10

------------

y=x-(-4)=x+4

3x-(x+4)=-10

3x-x-4=-10

2x-4=-10

2x=-10+4

2x=-6

x=-6/2

x=-3

-3-y=-4

y=-3-(-4)=-3+4=1

x=-3, y=1. (-3, 1).

I need help on question 7 and 8
DanielleElmas [232]
7.
remember
(ab)/(cd)=(a/c)(b/d)
we can split them up
and
(x^m)/(x^n)=x^(m-n)

\frac{27k^5m^8}{4k^3*9m^2}=  \frac{27k^5m^8}{36k^3m^2}=( \frac{27}{36} )( \frac{k^5}{k^3} )( \frac{m^8}{m^2} )=( \frac{3}{4})(k^{5-3})(m^{8-2} )=( \frac{3}{4})(k^2)(m^6 )= \frac{3k^2m^6}{4}



9.

2 to 3
4(x-1)=15
to
4x-1=15
the distribuutive prperty
a(b-c)=ab-ac
what he did was
a(b-c)=ab-c

he did not distribute the 4 to the -1


4(x-1)+3=18
minus 3
4(x-1)=15
distribute  4 to x and -1
4x-4=15
add 4 to both sides
4x=19
divide by 4
x=19/4
