Answer: Hello mate!
A direct variation implies that, if y is the dependent variable that varies with the variable x; then: y = k*x where k is a real number.
An inverse variation has the form y = k/x where also k is a real number.
them, if we define s as the hours that Bob spends studying, and b as the hours that he spends playing baseball, then the equation that represents the score is:
Score(s,b) = k*s/b
we know that if s = 6, and b = 7, then the score is 72; with this information, we could obtain the value of the constant k.
score(6,7) = 72 =k*6/7 = k*
then k = 72*(7/6) = 61.7
now if s = 4 and b = 6, the score that he should expect is:
score( 4, 6) = 61.7*(4/6) = 41
I believe the smallest would be D since even though B is a decimal with a lot of zeros in front of the #, B is still a positive # and D is a negative number being lower in the # line, so D or -200 would be the smallest
The area is 448.5
(13 × 29) + (11 × 13)1/2
80%
Ummm bro the explanation is simple he keeps 8/10 and he saves 2/10 sooo
8/10 x 10 = 80/100 spends 80%
2/10 x 10 = 20/100 saves 20%
Easy peasy...
Okay so #2 is (3,-2) so its A
and #3 is (-2,15) so its B
