Y=4x. The COP (constant of proportionality) is 4, which represent the “k”
y equals the # of hours u practiced so u substitute y for the # of hours and then solve for x. if im right u multiply x times 7 and u get how many minutes per week u practice the new song. and just the x represents what u practice in a day
210=7(15+x)
210/7=15+x
30-15=x
15 min =x
245=7(15+x)
245/7=15+x
35-15=x
20=x
315=7(15+x)
315/7=15+x
45-15=x
30 min=x
Hey there
_________________
The correct answer is:
f(x+5)=(x+5)^2+3(x+5)-10
f(x+5)=x^2+10x+25+3x+15-10
f(x+5)=x^2+13x+30 and f(x+5)=x^2+kx+30 so
k=13
Now factor x^2+13x+30
Find j and k such that jk=ac=30 and j+k+b=13 so j and k are 10 and 3 so
(x+3)(x+10)
So the two zeros occur when x=-3 and -10 the smallest of which is:
x=-10
