Answer:
Discriminant = 93, two real roots/solutions
Step-by-step explanation:
Discriminant = b² - 4ac = (9)² - 4(3)(-1) = 81 + 12 = 93
Since 93>0, the quadratic equation has two real roots/solutions.
Answer:
let the number of ride ticket be x and that of the food ticket be y
x+y=32
1.50x+3.25y=90
y=32-x
1.50x+3.25(32-y)=90
1.50x+104-3.25y=90
-1.75x=90-104
-1.75x=-14
x=14/1.75
x=8
y=32-x
y=32-8=16

<u>Answer:</u>
<h2>A = 15 u²</h2>
<u>Explanation:</u>
according to the coordinates the triangles is right at the pair (2, -3)
the area of the triangle = height × base × 1/2
the <u>height</u> is the line passing through the pairs (-1, 6) and (2, -3)
h² = (2-(-1))²+(-3-6)²
h² = 3² + (-9)²
h² = 9 + 81
h² = 90
h = √90
the <u>base</u> is the line passing through the pairs (5, -2) and (2, -3)
b² = (2-5)²+(-3-(-2))²
b² = 3² + (-3+2)²
b² = 9 + 1
b² = 10
b = √10
A = h×b×1/2
A = √90×√10×1/2
A = √900×1/2
A = 30×1/2
A = 15 u²
