Answer:

1/5 x (5m - 3) or 0.2 (5m -3)

Step-by-step explanation:

1. We convert 1 2/5 to 7/5 = 7/5m - 3/5 x (2/3 m + 1)

2. factor out 1/5 from the expression = 1/5 x (7m - 3(2/3m + 1))

3. Distribute -3 through the parentheses = 1/5 x (7m - 2m -3)

4. Collect like terms = 1/5 x (5m - 3)

Identify the solution to the system of linear equations<br> Y=-x-2<br> Y=x-6
NikAS [45]

Answer:

(-4, 2)

Step-by-step explanation:

By looking at the graph, the solution to the system of linear equations will always be where they intercept. If they both are the same line it means that there are infinite solutions, and if they don't intercept at all, that means there are no solutions.

Help..... me .......please..........ITS URGENT
Vikentia [17]

Answer: 115, 2645

(x= 115, y= 2645)

Step-by-step explanation:

There are two methods to this, which is using the graph with each x and y value, or substituting in values.

I would suggest looking at the graph first and then substituting values so you know the equation is being satisfied by the ordered pair.

In this case, one way to check it could look like this (substituting y value):

y = 23x

2645 = 23x

x = 2645÷23

x = 115

RS is the perpendicular bisector of TU. Find x and y​
german

Answer:

x = 1

y = 30°

Step-by-step explanation:

is RS is ⊥ to TU then TS = US so we can use this equation to find 'x':

20x-3 = 5x+12

15x = 15

x = 1

we also know that RS intersecting with TU creates a 90° angle

if 3y = 90 then y = 30
