The matrix represents the system:

-3x+5y=15

2x+3y=-10, which is choice c. 


We can see it more clearly from the way we multiply matrices, as follows:

\[&#10;  \left[ {\begin{array}{cc}&#10;   -3 & 5 \\&#10;    \ 2  & 3 \\&#10;  \end{array} } \right]&#10;\] \cdot  \[&#10;  \left[ {\begin{array}{c}&#10;   x \\&#10;    y \\&#10;  \end{array} } \right]&#10;\]= \left[ {\begin{array}{c}&#10;   -3\cdot x+5\cdot y \\&#10;    2\cdot x+3\cdot y \\&#10;  \end{array} } \right]&#10;\]= \[ \left[ {\begin{array}{c} 15 \\ -10 \\ \end{array} } \right] \]

Mr. Gephart is traveling from his house to the history museum. How many meters will he travel to the museum? The distance from h
snow_lady [41]

Answer: 6700 meters

Step-by-step explanation:

From the question given, we are informed that Gephart is traveling from his house to the history museum and that the distance from home to the history museum is six and seven-tenths kilometers.

In order to know the distance in meters

that he will travel to the museum, we have to multiply the convert the distance given in kilometers to meters. This will be:

1000 meters = 1 kilometer

Therefore, 6 7/10km = (6 7/10 × 1000m)

= 6 7/10 × 1000

= 67/10 × 1000

= 67 × 100

= 6700 meters

He'll travel 6700 meters to the museum.

Romashka [77]

9.42 Units

Step-by-step explanation:

Since the angle shown is 90 degrees we can deduce that the rest of the arc is 270 degrees therefore we can make the fraction:

270/360; 360 being the total angle measurement of a circle

270/360 simplifies to 3/4

The fraction represents how much of the circle that arc covers

Now we have to find the circumference which would be

2(3.14)r

r = 2 therefore: 2(3.14)2 = 12.56

Now that we have the circumference of the WHOLE circle we multiply it by 3/4 to find out the arc length

Which gives us  9.42
