Answer:
1
Step-by-step explanation:
y2-y1
/
x2-x1
6 - 9
/
1-4
= -3/-3
which simplifies to 1
4x+6y=8
3x+y=9
y = 9 - 3x
4x + 6(9-3x) = 8
4x + 54 - 18x = 8
14x = 46
x = 23/7
y = 9 - 3(23/7)
y = 9 - 69/7
y = - 6/7
<span>You may deduce what it represents by analyzing the formula you just wrote.
Well, </span>the coefficient of linear expansion as the fractional change in length per degree of temperature change.
ΔL = c x L(initial) x ΔT
where c is the coefficient of linear expansion. You can rewrite the equation to give you c.
c = ΔL / [L(initial) x ΔT]
<span>Just substitute the variables and the answer will be
c = 0.000028. </span>
Now, what it represents.It may represent the extent to which the rod expands with temperature when compared to its original length.
Answer:
90°
Step-by-step explanation:
Actually the question should be AC is tangent to circle B at point C. What is the measure of angle BCA.
AC is tangent and BC is radius.
Radius is perpendicular to the tangent.
Therefore,
measure of angle BCA = 90°
Answer:
The number of miles traveled is the independent variable.
The amount of money spent is the dependent variable.
Step-by-step explanation:
They keyword here is "per". You are spending .6 dollars for every mile traveled
