Top Left is the correct answer because the y intercept is -3 and that is the only one that crosses at (0,-3)
I don't know what $89.25 represents in the question but I can just assume that he saved that much more. "x" represents how much more he needs.
No, he doe not represent the equation correctly. "x" should not be on the right side of the equation.
Let "y" represent the total amount of the bicycle.
The correct equation should look like:
89.25 + 129.85 + x = y
Best of Luck!

Step-by-step explanation:
Answer:
• discriminant: 73
• # of real solutions: 2
Step-by-step explanation:
Comparing the equation ...
2x^2 -9x +1 = 0
to the generic form ...
ax^2 +bx +c = 0
we find the coefficient values to be ...
a = 2; b = -9; c = 1
That makes the value of the discriminant, (b^2 -4ac), be ...
(-9)^2 -4(2)(1) = 81 -8 = 73
Since the discriminant is positive, the number of real solutions is 2.
Answer:
109.3 yard²
Step-by-step explanation:
Area of triangle = bh / 2
base is 23yd
height is 9.5yd
bh / 2 = 23 × 9.5 / 2
Area = 218.5 / 2
Area = 109.25 yd²; rounded to the nearest tenth is 109.3yd²
