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
Answer:
a. 
b. 
Step-by-step explanation:
In numerical expressions we write numbers with the mathematical symbols ( i.e. '+', '-' etc )
a. Given phrase,
Three fifths of seven,




b. One sixth the product of four and eight,




First make x the subject of f(x) = 2x - 10:-
2x = f(x) + 10
x = 1/2 f(x) + 5
mow replace x by hx) and f(x) by x:-
h(x )= 1/2 x + 5
Hey!
This could be rewritten as:
2x + 1 + 5x
We can add like terms together:
7x + 1
