Hello!

If you drive 40 miles in 1 houre, and 120 mils in 3 hours, your first fracton would be and your second fraction would have to beย .

Therefore, your answer would be A.ย =ย .

Brainliest please?

Answer from: Quest

the direct variation says that:

then the equation is of the form is given by:

where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

โ

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5 true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to โ(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from โ6. the value of y must be positive since the variable is inside absolute value signs.
