If you observer the value of x=0 and x=1, you can conclude that every 1 value of x increased, the f(x) will be increased by 0.5. The graph function should be:
f(x)= x/2
A positive difference means that the value should be always positive. To find 3 the positive difference of f(x) with 3 values of x apart, let use x=0 and x=0+3= 3. The difference would be:
f(x+3) - f(x)
f(3)- f(0)=
1.5 - 0= 1.5
The answer would be: 2
Answer:
D y = 9/x
Step-by-step explanation:
An inverse variation is of the form
xy = k where k is a constant
We can write this as
y = k/x
The only equation that is of this form is
D y = 9/x
Answer:
275 yards of ribbon need to be ordered
Step-by-step explanation:
Figure out how much ribbon, in inches, is needed altogether by multiplying the amounts of ribbon by how many boxes are expected to sell for both box sizes:
Small Boxes:
20 in • 225 boxes = 4500 in of ribbon needed
Large Boxes:
30 in • 180 boxes = 5400 in of ribbon needed
Add it up to see how much you need:
4500 + 5400 = <u>9900 in of ribbon needed in total</u>
<u />
There are 36 inches in 1 yard, so divide 9900 by 36 to see how many yards need to be ordered:
9900 ÷ 3 = 275 yards
(Alternatively, you could divide 9900 by 12 inches in a foot to get 825 feet. Then you would divide 825 by 3 feet in a yard to get 275 yards)
Answer:937.12
Step-by-step explanation:
Answer:
x = 25
Step-by-step explanation:
Since these 2 angles are vertical angles, then they are both equal. Set up an equation and then solve it.
75 = 4x - 25
75 + 25 = 4x
100 = 4x
100/4 = 4x/4
25 = x
Hope this helps. Brainly will be highly appreciated.
