Answer 1

Answer:

x=2

Step-by-step explanation:

First you put the equations in the form of y = mx + b

Then once they are like that it would look like:

y = -2x + 6

y = 3x - 4

So then you can set them equal to each other and it will look like this:

-2x + 6 = 3x - 4

Then you add 2x to both sides and get:

6 = 5x - 4

Next, add 4 to both sides and get:

10 = 5x

So then you will simplify by dividing both sides by 5 and getting:

2 = x

Which of the following shows the Commutative Property of Addition?

A.5+ 3 = 3+ 5

B.5 + 3 = 8

C.3+ 5 = 8

D. 5x 3 = 3 x 5

I need to know ASAP pls

Answers

Answer:

The Correct answer is A.

Step-by-step explanation:

The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer.

Ex: 3 + 5 = 5 + 3 Notice how the numbers are swapped but the answer remains the same. Both result in an outcome of 8.

Jk =5x+17,KL = x -1,JL=7x-9 find a range of possible values for x

Answers

Value of x in the triangle will have the range 9 < x < 25 .

Given,  JK = 5x+17, KL = x -1, JL = 7x-9

According to triangle property,

Sum of any two side of the triangle is greater than the third side.

JK = 5x+17

KL = x -1

JL = 7x-9

Case 1:

∴ JK +KL > JL

5x+17  + x -1  > 7x-9

25 > x

Case 2:

KL + JL > JK

x -1 +  7x-9 >  5x+17

x > 9

Case 3 :

JK + JL > KL

5x+17  +  7x-9  >  x -1

x > -9/11

Therefore the range of possible values of x : 9 < x < 25 .

#SPJ4

Write an equation of the line graphed below.

Answers

Answer:

y=1/2x+3

Step-by-step explanation:

So the slope formula is y=mx+b. Where mx is the slope and b is the y-intercept. In this case our slope is 1/2 because we rise by one unit and run by 2 units. The y-intercept in this case is 3 because on the y axis the line intersects over 3.

Hopefully that helped :).
