2.x=-33/8
3.x=10
4.x=5
Step-by-step explanation:
What value of x makes the equations true? show work
Answer:
see below
Step-by-step explanation:
-2x + 9 < x − 9
Add 2x to each side
2x-2x + 9 < 2x+x − 9
9 < 3x-9
Add 9 to each side
9+9 < 3x
18 < 3x
Divide each side by 3
18/3 < 3x/3
6 < x
Open circle at 6 line going to the right
The equation would be
8 = 6x + 2
the “number” is unknown, so it’s x.
6 times the number would be 6x.
The sum of 6x and 2 means adding together 6x and 2, so 6x + 2
And it’s supposed to equal 8
Answer: Section formula
Step-by-step explanation:
Given
The line segment AB with endpoints
and
is divided by a point X in the ratio 1:2
To verify that X divides the line segment in the ratio 1:2, we will use section formula. Section formula tells the coordinates of the point which divide the line segment in the certain ratio or vice-versa.
We will assume that X divides AB in k:1 and insert the values in the section formula. If the ratio k:1 comes out to be 1:2, then it verifies the claim.
