Suppose a curve is given by the parametric equations x=f(t), y=g(t), where the range of f is [2, 7] and the range of g is [1, 4]. What can you say about the curve? You must select all correct choices to get full credit on this problem.
A. The curve is the line with endpoints (-1, -1) and (4, 10).
B. The curve must lie inside a circle with center (-1, -1) and radius 0.5.
C. The curve is completely contained in the rectangle [-1, 4] by [-1, 10].
D. The curve is a circle with center (-1, -1) and radius 10.
E. The curve must lie outside the rectangle [-1, 4] by [-1, 10].
F. Nothing can be said about the curve.

the two may have that, even a breakdown is probably offered

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

starting with:    

5 + x - 12 = 2x - 7   

5 + x - 12 - x = 2x - 7 - x (subtract x from both sides)   

5 - 12 = x - 7 (combine and cancel x's from both sides)   

5 - 12 + 7 = x - 7 + 7 (add 7 to both sides)   

0 = x (add numbers together on both sides)       

so in order for the equation to be true, x must be 0.   

trying x = -0.5   

5 + x - 12 = 2x - 7 (original equation)   

5 + -0.5 - 12 = 2(-0.5) - 7 (plug in value of x)   

5 + -0.5 - 12 = -1 - 7 (did multiplication)   

-7.5 = -8 (did addition on both sides)       

since -7.5 is obviously not equal to -8, the value of -0.5 for x is wrong.   

trying x = 0   

5 + x - 12 = 2x - 7 (original equation)   

5 + 0 - 12 = 2(0) - 7 (plug in value of x)   

5 + 0 - 12 = 0 - 7 (did multiplication)   

-7 = -7 (did addition on both sides)       

since -7 equals -7, that demonstrates that the value of 0 for x is correct.   

trying x = 1   

5 + x - 12 = 2x - 7 (original equation)   

5 + 1 - 12 = 2(1) - 7 (plug in value of x)   

5 + 1 - 12 = 2 - 7 (did multiplication)   

-6 = -5 (did addition on both sides)       

since -6 is obviously not equal to -5, the value of 1 for x is wrong.
