I'm thinking this is what the problem looks like:
. The first thing to do is to move the
over to the other side because it has a common denominator with the other side. Doing that and at the same time combining them over their common denominator looks like this:
. The best way to solve for x now is to cross-multiply to get 3(4-x)=-4(x-4). Distributing through the parenthesis is 12 - 3x = -4x + 16. Solving for x gives us x = 4. Of course when we sub a 4 back in for x we get real problems, don't we? Dividing by zero breaks every rule in math that there ever was! So, yes, the solution is extraneous.
The answer is here. Hope I did help you.
Answer:
51 mph
Step-by-step explanation:
1734 miles
---------------- (per)
34 hours
you would divide. think of it as a fraction
1734
----
34
the numerator is miles and the denominator is hours. divide the numerator (the top number) by the denominator (the bottom number).
1734/34= 51
therefore, martino drove 51 miles per hour
Hope this helps!
ANSWER
D.
EXPLANATION
The given graph rises on the left and falls on the right.
This implies that the degree of the function is even.
Since the graph opens downward, the coefficient of the leading term must be negative.
The graph graph of the function also has 3 intercepts with one of them having an even multiplicity.
This means that the degree must be 4.
Therefore the last choice is correct.
Third angle =180° - (149° + 9°)
= 22°
Thanks me if is correct!
