16 is the solution to this if you're multiplying the 2
Answer:
-3 is the value of k in g(x)=kf(x)
Step-by-step explanation:
Both functions cross nicely at x=-3 so I'm going to plug in -3 for x:
g(x)=kf(x)
g(-3)=kf(-3)
To solve this for k we will need to find the values for both g(-3) and f(-3).
g(-3) means we want the y that corresponds to x=-3 on the curve/line of g.
g(-3)=-3
f(-3) means we want the y that corresponds to x=-3 on the curve/line of f.
f(-3)=1
So our equation becomes:
g(-3)=kf(-3)
-3=k(1)
-3=k
So k=-3.

Answer:</h3>
<u>Perimeter of rectangular garden = 2(l + b)</u>
- 2(y + 2 + 4y - 1)
- 2y + 4 + 8y - 2
- 10y + 2.
<u>Hence, perimeter of given garden is 10y + 2</u>.
It’s a rational number when you round it to any place value, if you don’t round, it’s not rational.
Rational numbers are fractions and decimals that don’t go on and on forever, and no fractions that are over 0.
Since .3333 doesn’t go on forever, it’s rational.
It’s rounded to the Ten Thousandths.
Examples:
Rational: 4/5 .35 6/8
Not Rational: .3333333 (forever) 4/0 6/0 .555555 (forever).
Hope this helps :)
