Answer:
.47
Step-by-step explanation:
1/10= .1
0.0.47/.1=.47
-1 x .47=0.47
I think C is the answer.
In the box, everything is evened out and nothing is bigger than the other.
So, your answer:
C
Answer:
no it is not.it depends on angles .
The error is when she added 4 to both sides.
Instead, she should divide both sides by -4 to undo the multiplication. Specifically, the multiplication between the -4 term and the (x-2)^2 term.
This is one possible correction of what her steps could look like.
In the third step, I'm dividing both sides by -4. In the sixth step, I'm applying the square root to both sides to undo the squaring operation. Then two steps later, I'm adding 2 to both sides to undo the "-2", which helps fully isolate x.
The only solution is x = 2, so it's the only x intercept. You can verify this answer by plugging x = 2 back into the original equation at the very top. You should end up with y = 0.
Note: The term "root" is another name for "x intercept".
Answer:
The two numbers are 100 and 10
Step-by-step explanation:
Let's call the two numbers x and y.
Add 7 to both sides of the first equation to isolate x:
Substitute:
