Can anyone help me with the answer to this please?

stiks02 [169]

Answer:

Step-by-step explanation:

To find the inverse function switch variables out and solve for y

y=(x+3)/x swap variables to get

(y+3)/y=x then solve for y

y+3=yx

y-yx+3=0

y-yx=-3

y(1-x)=-3

y=-3/(1-x)

y=3/(x-1)

Which graph represents the solution set of the system of inequalities?

vivado [14]

Solve first for the solution of the inequalities. This can be done by replacing first the inequalities sign with the equal sign.

x + y = 1
2y = x - 4

The values of x and y from the system of linear equation are 2 and -1. This means that the intersection of the lines should be at point (2, -1).

Substitute 3 to x and determine the value of y from the second inequality.
2y ≥ x - 4

Substituting,
2y ≥ 3 - 4, y ≥ -1/2

Hence, the solution to this item should be the fourth one.

If JM = 5x – 8 and LM = 2x – 6, which expression represents JL?

Delvig [45]

The green line is LM
The red line is JM
The blue point is at the coordinates (2/3, -14/3)

you'll have to excuse the way my graph looks. my graphing application on my computer is weird
