Answer: Yes... 3.25*8=26 so the amount of money is exact
Given a quadratic function
y = 4x² - 19x - 5
or i will write it as
4x² - 19x - 5 = y
Zero of the function is when y have the value of zero.
So the quadratic equation will be
4x² - 19x - 5 = y
4x² - 19x - 5 = 0
Now make the equation to intercept form by factorization
4x² - 19x - 5 = 0
(4x + 1)(x - 5) = 0 (this is intercept form)
Solution 1
4x + 1 = 0
4x = -1
x = -1/4
Solution 2
x - 5 = 0
x = 5
SUMMARY
-1/4 and 5 are zero function of f(x) = 4x² - 19x - 5
You can make 8 triangles from this shape.
It’s d
Because…
A= 77% which is equivalent to .77, which is less than 1
B= 10/8 because it is a little more than one
And by looking at the line you can see how C and D are marked correctly because both of them are over 2, and D is a little bigger than C
The answer is 22.6 for the top one and 6x+14y+13 for the second one... the coefficient for y=14
