Answer:

The answer to your question is: letter B

Step-by-step explanation:

Data

°C °F

0 32

35 95

Process

Find slope m = (95 - 32) / ( 35 - 0)

m = 63 / 35

m = 9/5

Line equation

( y - y1) = m(x - x1)

y = °C x = °F

°C - 0 = 9/5 ( °F - 32)

°C = 9/5( °F - 32)

Does anyone know the answer to this!?

Answer:

$|A_y|=\left|\begin{array}{cc}12&7\\ \\17&-51\end{array}\right|$

Step-by-step explanation:

You can use these Cramer's formulas to solve for x and y:

$x=\dfrac{|A_x|}{|A|},\\ \\y=\dfrac{|A_y|}{|A|},$

where

$|A|=\left|\begin{array}{cc}12&-13\\ \\17&-22\end{array}\right|\\ \\ \\|A_x|=\left|\begin{array}{cc}7&-13\\ \\-51&-22\end{array}\right|\\ \\ \\|A_y|=\left|\begin{array}{cc}12&7\\ \\17&-51\end{array}\right|$

So,

$|A_y|=\left|\begin{array}{cc}12&7\\ \\17&-51\end{array}\right|$

Question 21: 24 minutes

$\frac{3}{\frac{3}{2} } = \frac{x}{12}$

x = $(\frac{3}{\frac{3}{2} })(12)$

x = 24

Question 22: 20 centimeters

x = one side of the square

x² = 25

x = 5

4x = perimeter

4(5) = perimeter

20 = perimeter

Question 23: 17 sides

Hexagon = 6 sides

Octagon = 8 sides

Triangle = 3 sides

Total amount of sides = 6 + 8 + 3
