Answer:

32x - 4

Step-by-step explanation:

2x(6+2+8)-4

Frist, we would do 6+2+8

2x(16)-4

Then, we would do 2x ⋅ 16

32x - 4

A circle in the xy-plane is centered at (3, 0) and has a radius with endpoint (1, 8/3 ). Which answer choice is an equation of t

gayaneshka [121]

Answer: (x - 3)² + y² = $\frac{100}{9}$

<u>Step-by-step explanation:</u>

Circle Formula: (x - h)² + (y - k)² = r² ; (h, k) is the center & r is the radius

Use the distance formula for (3, 0) and (1, $\frac{8}{3}$ )

$r = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

$r = \sqrt{(3-1)^{2}+(0-\frac{8}{3})^{2}}$

$r = \sqrt{(2)^{2}+(-\frac{8}{3})^{2}}$

$r = \sqrt{4+\frac{64}{9}}$

$r = \sqrt{\frac{36}{9}+\frac{64}{9}}$

$r = \sqrt{\frac{100}{9}}$

$r = \frac{10}{3}$

****************************************************

Center (h, k) = (3, 0) Radius (r) = $\frac{10}{3}$

(x - h)² + (y - k)² = r²

(x - 3)² + (y - 0)² = ( $\frac{10}{3}$ )²

(x - 3)² + y² = $\frac{100}{9}$

Suppose that x=6 and y=8. If y is inversely related to x, what is y when x=3?

andrey2020 [161]

$\bf \qquad \qquad \textit{inverse proportional variation}\\\\
\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad y=\cfrac{k}{x}\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\
\textit{we also know that }
\begin{cases}
x=6\\
y=8
\end{cases}\implies 8=\cfrac{k}{6}\implies 48=k
\\\\\\
therefore\qquad \boxed{y=\cfrac{48}{x}}
\\\\\\
\textit{when x = 3, what is \underline{y}?}\qquad y=\cfrac{48}{3}$

Find the value of x if m || 1. mZ1 = 2x + 44 and m25=5x+ 38. The diagram is not to scale

AleksAgata [21]

Answer:

A. 2

Step-by-step explanation:

m<1 = 2x + 44

m<5 = 5x + 38

Since line m is parallel to line l, therefore:

m<1 = m<5 (corresponding angles)

2x + 44 = 5x + 38 (substitution)

Collect like terms

2x - 5x = -44 + 38

-3x = -6

Divide both sides by -3

-3x/-3 = -6/-3

x = 2
