You use substitution method by subtracting the (x) from both sides in the second equation and end up getting (y= -x+15) and substitute in the y and then once you get the y find the x

Please help im stuck on this one i font know how to do inverse operarions​
Goshia [24]

Answer:

107.500

Step-by-step explanation:

5.450.000-75.000=5.375.000

5.375.000:12 1/2=5.375.000:25/2=5.375.000*2/25=430.000

430.000:4=107.500

+ and - ,

*  and :

are inverse  operations

Where it is an operation and the result is a number , we have to do the inverse operation for finding the initial number.

verifying :

107.500*4*12 1/2+75.000=5.450.000

Answer:

8 is the length of JB

Step-by-step explanation:

<u>Key skills needed: Equations, Congruence</u>

1) We need to find out an equation to make based on the lengths that are given. ΔJMB is congruent to ΔKMB because of Side-Angle-Side:

  • JB is congruent to BK
  • Angle MBK would be a right angle, since it is supplementary to the right angle JBM. Since both are right angles they are congruent.
  • Both triangles have the side BM. Using the reflexive property, BM is congruent to itself, so there you go --> Side-Angle-Side

2) Now since both triangles are congruent, we can make the equation that the length of JM is congruent to the length of MK, using the fact that: If triangles are congruent, then corresponding parts are congruent.

3) This means that 16x -24 = 4x

Subtract 16x from both sides : -24 = -12x

Divide by -12 on both sides and get x = 2

4) Substitute x into the length of JB (16x-24)

16(2)-24 = 32-24 = 8

5) Therefore, the length of JB is 8

For the following​ equation, find three ordered pair solutions by completing the table. Then use the ordered pairs to graph the
Viktor [21]

The graph of the linear equation can be seen in the image below.

<h3>How to complete the table?</h3>

Here we have the linear equation:

y = -4x + 8

And we want to find 3 ordered pairs, to do so, we need to evaluate x in different values.

if x = 0 then:

y = -4*0 + 8 = 8

So we have the ordered pair (0, 8).

if x = 1 then:

y = -4*1 + 8 = 4

Then we have the ordered pair (1, 4)

If x = 2 then:

y = -4*2 + 8 = 0

Then we have the ordered pair (2, 0).

Now that we have these 3 ordered pairs, we can graph them in a coordinate axis and then connect them with a line, we will get something like the graph below.

That is the graph of our linear equation:
