Top one
y=-1.7+11y
x=-1.55+10y
Bottom one
y=-7.14-5x
Therefore, the answer is D: 20,000
12x^8 multiply the leading terms (2and 6) then add exponents (5and3)
9. Area of a triangle is proportional to height. If the height increases by a factor of 4, then ...
The area will increase by a factor of 4. . . . . (2nd selection)
10. The base lengths and height are needed:
• 5 mm
• 8 mm
• 10 mm
(x - 2)^2 will always be positive and will have a minimum value of 0
so f(x) will have minimum of 2
Range is [2,∞)
