We have a dilemma here, there is a variable and constant numbers in this equation. No fear, this is when like terms comes into play, where you can only combine two numbers that have the same ending, whether it be variables, exponents, e.t.c.
Distribute :
4 + 16 - 12(1 + 2x)
4 + 16 - (12(1) + 12(2x))
4 + 16 - 12 + 24x
Use PEMDAS (Add left to right) :
4 + 16 - 12 + 24x
20 - 12 + 24x
8 + 24x
24x + 8
Answer:
The vectors form an obtuse angle.
Step-by-step explanation:
On a graph, -5, 1 is in the second quadrant and 8, 6 is in the first. The angle about the orgin is obtuse.
Finding the dot product between them results in a negative, which also means the angle is obtuse.
Solutions
We know that a ticket costs £14.50 and it is increased by <span>7% in price. To solve the problem lets use variables.
Let the Variable Y</span><span> = 7% of 14.5
Equation: Y = P% </span>×<span> (X)
Solve for our equation Y
Y = P% </span>×<span> (X)
Y = 7% </span>×<span> 14.5
Now lets convert the percent to a decimal:
Percent = Out of 100
Percent = 7% / 100 = 0.07
Y = 0.07 </span>×<span> 14.5
Y = 1.015
