Simple...if you want to solve this.....
49-7x=21
Isolate the variable (x)
49-7x=21
-49 -49
-7x=-28
Now, simplify...
x=4
Thus, your answer.
It’s H. You have to set up an equation: y=10x-11. -11 is the starting value, so you put it at the end. You add ten each time, so you put 10x. Just plug in 100 for x, and you’ll get 989
Answer:
y = (x + 1 ) ^2
Step-by-step explanation:
y = x^2 + 2x + 1
Completing the Square
y = ( x + 1 ) ^2 + 0
Answer:
Those angles are in opposite either in vertical or horizontal. They are opposite angles
