We know that, In a Right Angled Triangle :
✿ (Hypotenuse)² = (First Leg)² + (Second Leg)²
From the Diagram :
✿ Hypotenuse = x
✿ First Leg 
✿ Second Leg 




f(x)=−7x 2 +8x+2f, left parenthesis, x, right parenthesis, equals, minus, 7, x, squared, plus, 8, x, plus, 2 What is the value o
vlada-n [284]
The discriminant of the function is 120, and the function has 2 different x-intercepts
<h3>How to determine the discriminant?</h3>
The function is given as:
f(x) = -7x^2 + 8x + 2
The discriminant (d) is calculated using:
D =b^2 - 4ac
So, we have:
D = 8^2 - 4 * (-7) * 2
Evaluate
D = 120
Because the value of D is greater than 0, then the function has 2 different x-intercepts

Answer:
y + 1 = 4/3(x - 9)
Step-by-step explanation:
Point-slope form: y - y₁ = m(x - x₁)
Substitute the numbers into the equation:
y - (-1) = 4/3(x - 9)
y + 1 = 4/3(x - 9)
