Answer: Rotate 90 degrees clockwise, then reflect over the y axis
Step-by-step explanation:
Let's convert the word descriptions into mathematical equations first for illustration.
f(x) = x^2 - x - 12
g(x) = -2.5x - 2
Then, we equate g(x) and f(x). The final equation becomes
x^2 - x - 12 = -2.5x - 2
Then, we simplify by transposing and combining like terms.
x^2 - x + 2.5x -12 + 2 = 0
x^2 + 1.5x - 10 = 0
Since this is a quadratic equation, we find the roots by using the quadratic formula
where a = 1, b = 1.5 and c=-10
Thus, the answer is x = 2.5, -4.
Answer: A
Step-by-step explanation:
First, we need to find out how much the price increased by.
$4.50 - $3.75 = $0.75
Now we have to figure out what percent $0.75 is of $3.75. To do this, we divide $0.75 by $3.75.
The answer is 0.2. Now, we convert this into a percent by moving the decimal to the right by to spaces: 0.2 = 20%
The percent of increase is 20%.
