Answer:
D. The scale factor is 1:840
Step-by-step explanation:
Make 630 ft into inches, so 7560
Then make it 9/7560, which simplifies to 1/840
Answer:
what is the fourth measurement I think Ur question is wrong pls correct it
Answer:
3 times the number of yards
Let f represents the number of feet
f = 3 * y
Step-by-step explanation:
Number of feet 3 6 9 12
number of yards 1 2 3 4
1*3 = 3
2*3 - 6
3*3 =9
4*3 = 12
number of feet is 3 times the number of yards
Let f represents the number of feet
and y represents the number of yards
number of feet is 3 times the number of yards
f = 3 * y
The inverse for this operation would be to find the equation for "x" since it's the equation for "y." Inverse means reverse in direction or position. To find the inverse of "y = -3/(x+4) , you would need to start by using the order of operations. Here's where you start:
y<span> = -3/(x+4)
</span>
Next, you want to get the (x+4) to the other side. Since it's being divided, multiply this number on both sides.
y = -3/(x+4) ⇒ (x+4)y = -3
Now, you need to get y on the opposite side. Divide both sides by y.
(x+4)y = -3 ⇒y÷ (x+4)y = -3 ÷ y
The y's cancel on the left, so you would have the equation:
x+4 = -3/y
Now to get x by itself, subtract 4 from both sides.
x+4 = -3/y
-4 -4
⇒x = -3/y -4 is your final answer.
