First question. The midpoint of SR is...

Blizzard [7]

The formula of a midpoint SR:

$M\left(\dfrac{x_S+x_R}{2},\ \dfrac{y_S+y_R}{2}\right)$

We have

S(4, 1) and M(7, -5)

Substitute:

$\dfrac{4+x_R}{2}=7\qquad|\cdot2\\\\4+x_R=14\qquad|-4\\\\x_R=10\\\\\dfrac{1+y_R}{2}=-5\qquad|\cdot2\\\\1+y_R=-10\qquad|-1\\\\y_R=-11$

<h3>Answer: R(10, -11)</h3>

1-3. Find the center point, the radius and the diameter for the following equation: x² + y2 = 16

kogti [31]

Answer:

Center: (0, 0)

Radius: 4

Step-by-step explanation:

Circle Standard Equation: (x - h)² + (y - k)² = r²

(h, k) is center

r is radius

We see that our <em>h</em> and our <em>k</em> are both 0.

∴ Our center is (0, 0), origin.

We see that our r² = 16

√r² = √16

∴ Our radius is equal to 4

Solve 8(x+2)=36.......

brilliants [131]

We have to use the Distributive Property in this equation.
By the Distributive Property,
$8(x+2)=36
$
becomes
$8x+16=36.$
Now we need to isolate x. Remember PEMDAS?
$8x=20$
$x=20/8$
Simplify the right side.
$x=10/4$
$x=5/2$
