Answer:In expression x-2 coefficient of x is equal to one.
Let a be "a" x's coefficient.
If we put "a" to Your equation, it should be looks like:
ax-2
We know that there is only one x, so expression ax have to be equal x
Now we get
From this equation we know that coefficient x "a" is equal to 1.
20.
Just use Pythagorean theorem.
Trust me lol
When a line is reflected along the x axis, the sign of the x coordinate of the points on the line remains the same while that of the y coordinate is reversed. Therefore,
For point A, the x coordinate is - 2 and the y coordinate is - 1. After relection over the x axis, it becomes
(- 2, - -1)
= (- 2, 1)
For point B, the x coordinate is - 1 and the y coordinate is - 3. After relection over the x axis, it becomes
(- 1, - -3)
= (- 1, 3)
The coordinates after reflection are A(- 2, 1), B(- 1, 3)
Answer:
20
Step-by-step explanation:
ones= 1
tens= 10
Hundreds= 100
The difference between ones and tens is the 0. ones=1. tens=10
<u>2</u>4
The 2 is in the beginning so its the 10's place. The 4 is the second number so its in the ones place
