hi Niña,   I just moved to Florida so I'm not too familiar with FCAT.  I have tutored for the SAT/ACt since 2006 and just by looking at a sample test book on the FCAT website, I can tell you that the math tested for 10th grade is similar to the SAT and ACT.  I'm guessing you...

Hi Megan,   This problem is easier if you are able to translate the word problem into mathematical equivalents.   for example, "of" in math means multiplication   ...there are other examples I can share with you   for this problem 32...

hi Sherry,   Could you tell me a little more what the 54.1 and 46 numbers mean.  Is this percent shared segments?   I'm not sure what you mean by "n genomes"   Being female, your father would have passed the X chromosome to you and the Y chromosome...

Please see my video (see "Videos" section -- just submitted) hope it helps

since you are given the point to test as (-1,-8) that means x = -1 and y = -8 So, you plug in this values unto your equation.  Plug in -1 for x and -8 for y   -8 = -1 - 5   but since it is NOT true that -8 = -6, the point (-1,-8) is NOT a solution for this equation...

To start in point-slope form, y = mx + b 3 = 1/2(-2) + b 3 = -1 + b so b = 4   Point-slope equation is y = (1/2)x + 4   In Standard form, Ax+Bx = c first multiply both sides of your equation by 2 2y = x + 8  substract...

An even function is symmetric with respect to the y axis.  Or, f(x) = f(-x)   This function is symmetry with respect to the y axis, so it is even.

since y = -2x + 7   then   3 = -2(-2) + 7 however,   3 ≠4 + 7 3 ≠11   so (-2,3) is not a solution

f(x) = √x - 8

Slope intercept form is the form y= mx+b where m is the slope and b is the y-intercept.   First, find your slope and plug into the form above   slope can be remembered as "rise over run."  and your "rise" will be Y2-Y2 or  3-(-7) =...
