Suppose the solution set of a certain system of linear equations can be described as x 1 = 5 + 4 x 3, x 2 = -2 - 7 x 3, with x 3 free. Use vectors to describe this set as a line in set of real numbers R3.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

if you would like with a question it is easy to get an answer by including some or multi choice options

step-by-step explanation:

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
