1 yard is equal to 3 feet
3÷2=1.5
1.5+3=4.5 feet
1.5 yards= 4.5 feet
Hope this helps!

You can get this by using the quadratic equation with a = 7, b = -1, c = -9
Answer:
The circumference of the circle is: "
37. 7 in." ; or, write as:
"
12
in. " .
______________________________________________________Explanation:______________________________________________________A square has all 4 (four) sides of equal length.
If the perimeter of the square = 48 inches;
the side length of each side of the square = "48 in. ÷ 4 = 12 in." ;
→ "12 in. = the diameter, "d", of the circle within the square" .
The formula for the Circumference, "C" , of a circle, is:
"C =

* d " ;
C =

* d ;
d = 12 in.
C = "
12
in. " ;
or; calculate the Circumference, "C", of the circle; using: "3.14" as an approximation for

;
C =

* d ;
= (3.14) * (12 in.) ;
= 37.68 in. ; round to: "
37. 7 in." .

Remember x is x and f(x) is same thing as y.
f(5) = 4
It is same thing as saying, when x = 5, y aka f(x) should be 4. Aka the point (5,4)
Let’s look at D, if x =5 then f(x)=5? No, it should equal 4. So this is wrong. It is also not linear. So NOT D
Lets look at C, if x =5 then
1/5(5)+3 =
5/5 + 3 =
1+3 =
4
So, f(x) aka y = 4. Is this correct? Yes when x =5, y indeed should equal 4, but it is not linear. So NOT C
Lets look at B, if x=5 then,
2^5 -28 =
32 - 28 =
4
So, f(x) aka y = 4. Is this correct? Yes when x =5, y indeed should equal 4, AND it is linear SO THE ANSWER IS B
Check A too, it gets y=14 so thats wrong as it is not 4.
