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.
(a) 48 %
(b) 74 %
Add the numbers associated with the name and then do 150 divided by that number, and then make the top number equal to 100. Whatever you did to make that top number 100 do the same thing to the bottom number.
So u multiply 4267/1 by 1/31 because 31/1 as a reciprocal is 1/32 so u will get:4267/32 - 133 11/32
Use keep, change, flip!
Ex: 1 / 3
— —
2 4
Keep the 1/2
Change the division sign to a multiplication sign
Flip the 3/4 to be 4/3
1 X 4
— —
2 3
Then, multiple and simplify as usual!
1 X 4= 4
2 X 3= 6
4 = 2
— —
6 3
The answer would be 2
—
3
Hope this helps, brainliest please! :)
