Answer:
x + 10 = x² + 1
(third option listed)
Step-by-step explanation:
assuming that you meant:
, because otherwise there would be no equivalent relationships,
(goal: isolate x on one side of the equation whilst having x on the other side of the equation also, like the equation in the question)*
x + 10 = x² + 1
-1 -1
x + 10 - 1 = x²
[find √ of both sides to isolate x]
(equation in problem)
{note: there's no reason to not simplify the equation to
, but the question leaves the equation that way, so I didn't simplify it either}
*I used this goal to decide which equations seemed about right, and then trying to test things out in my head
10 : 90; 10÷10= 1; 90÷10= 9; 1:9 or 1/9
Hope this helps
First of all, assuming that the "ground level" is 0;
The lift is not starting from 0, so we also need to account for the extra 15 meters above the ground the lift is.
The total distance the lift would cover in the downward direction: 15+350=365m
Now, you know that the lift covers 5 m/min
Therefore, 5x=365 (ignoring units because they can complicate things)
x=365/5
x=73 minutes
Therefore, they would take 73 minutes to reach 350 m deep into the ground with a starting position 15 m above the ground.
Hope I helped :)
Answer:
yes it does
Step-by-step explanation:
as you can see,
in a function, we don't have more than one y for a x, so here we have one y for each x. then it is
Answer:
A) JK and LM will be parallel to each other.
Step-by-step explanation:
On reflection on
line the x co-ordinate changes with y co-ordinate and y co-ordinate changes with x co-ordinate

Points on line EF

On reflection of this line on
the new points we get for line JK are

Points on line GH

On reflection on y=x line the new points we get for line LM are

Slope of line JK

Slope of line LM

For two line to be parallel, their slopes will be same.

Since slopes of lines JK and LM are same therefore we can say that these are parallel to each other.
