Answer:
False.
Step-by-step explanation:
Any straight line may have infinite number of points (solutions) lying on it.
Therefor, straight line 'l' can't have exactly two solutions.
Line 'l' will have infinitely many solutions.
Exactly one or two solutions are possible only when two lines or functions intersect each other.
Therefore, answer is false.
Answer:
The answer is
<h2>21.45 g/cm³</h2>
Step-by-step explanation:
The density of a substance can be found by using the formula
From the question
mass of platinum = 214.5 g
volume = 10 cm³
It's density is
We have the final answer as
<h3>21.45 g/cm³</h3>

Answer:
y - 2 = (-3/7)(x + 5)
Step-by-step explanation:
Recall that the slopes of a line and another line perpendicular to the first are negative reciprocals.
The slope of the given line is 7/3. The negative reciprocal of that is -3/7. Thus, we immediately eliminate the fourth answer choice.
We must now find the equation of the perpendicular line, with slope -3/7, that passes through (-5, 2). We'll do that using the point-slope formula for the equation of a straight line.
That formula is y - k = m(x - h), where m is the slope and (h, k) is the given point.
Substituting 2 for k, -5 for h and -3/7 for m, we get:
y - 2 = (-3/7)(x + 5). This matches the 3rd given possible answer.
The answer is c which is correct
