Answer:

Value of x1 = 10 and x2 = -3

Step-by-step explanation:

$when \: we \: multiply \: the \: above \: matrices \\ we \: get \\ 2x1 + 6x2 = 2 \: \: \: \: and \\ 0x1 + 1x2 = - 3 \\ then \: \: x2 = - 3 \\ on \: substituting \: x2 = - 3 \:\\ in \: first \: equation \: \\ 2x1 + 6( - 3) = 2 \\ 2x1 - 18 = 2 \\ 2x1 = 20 \\ x1 = \frac{20}{2} \\ x1 = 10$

What is the length of a segment with endpoints at F(6, 4) and G(14, 19)? Round to the nearest whole number.

Mila [183]

Answer:

Step-by-step explanation:

d = √( (x₂ - x₁)² + (y₂ - y₁)² )

= √( (14 - 6)² + (19 - 4)² )

= √( 8² + 15² )

= √( 64 + 225 )

= $\sqrt{289}$

= 17

a city that has an elevation of 15 meters is closer to sea level than a city with an elevation of -10 true or false? explain you

12345 [234]

Answer:

False

Step-by-step explanation:

At sea level, elevation is 0. This means that we can portray sea level as being the midpoint of distances below sea level and distances above sea level.

Thus, a distance of 1 m below sea level = - 1 is equivalent to a distance of 1 m above sea level albeit in opposite directions.

Hence, an elevation of 15m above sea level is greater in distance Than an elevation of - 10 m below sea level because the absolute value of 15 is greater than the absolute value of 10.

|15 - 0|= 15

|-10 - 0| = 10

Hence, elevation of - 10 below Sea level is closer to sea level than elevation of 15 above sea level
