Answer:
point slope form is below. since you have the slope already, all you have to do is plug in the point for x1 and y1 and then the slope for m
y - y1 = m(x -x1)
y - 2 = -4 (x - 2) (this is the equation)
Step-by-step explanation:
A quadratic equation has the general formula expressed as:<span>
ax^2 + bx - c = 0
This equation can be solved by the quadratic formula which is expressed as:
x = ( -b (+ or -) √(b^2 - 4ac) / 2a
From the given equation,
a = 9
b = -54
c = -19
x = ( -(-54) (+ or -) √((-54)^2 - 4(9)(-19)) / 2(9)
x1 = 19/3
<span>x2 = -1/3</span></span>

Step-by-step explanation:
• General quadratic equation:
• sum of roots → 4 + 5 = 9
• product of roots → 4 × 5 = 20
• substitute:
Answer:
It costs 19 cents or 0.19 dollars per fluid ounce.
Step-by-step explanation:
4.75 divided by 25 is 0.19. 0.19 is 19 cents.
I just worked this question. None of those are the answers
First we remove the brackets:
4x + 16 = 2x + 4
Group like terms:
4x - 2x = 4 - 16
Evaluate:
2x = -12
x = -12/2 = -6
