Hello, you forgot to provide the graphs but anyway this problem can be solved without them. If you want a graph where y is increasing by 1/2 each time x increases by 1, then you want a general equation in the form of:

y= \frac{1}{2}x+c where c is any constant.

Assuming the value of 0 for c, notice that when x is 1, y is 1/2, and when x is 2, y is 1. Therefore 1/2 was increased for y upon increasing 1 for x.

ANSWER: The graph of y= \frac{1}{2}x+c.

Ralph buys a desk that regularly sells for $250 and a desk chair that regularly sells for $145. both items are on sale at 15% of
Lunna [17]
C) (0.85 + x/100)(250+145) does not give the correct answer.

Explanation
A) works; adding the two costs together is 250+145=395.  We multiply this by 0.85 because 100%-15%=85%=0.85.  We also have x% tax, which is represented by x/100, added to 100% of the value, or 1.00.  Altogether this gives us 
395(0.85)(1+x/100) = 395(0.85 + (0.85x/100)) = 395(0.85) + 395(0.85x/100)
= 395(0.85) + 395(0.0085x)
B) works; we have 250+145 for the original price; we have 85% = 0.85 of the value; we also have 100% + x%, which is (100+x)/100.
C) does not work; (0.85+x/100)(395) does not take into consideration that you are finding the tax after taking the 85%.  This will simplify out to
0.85*395 + (x/100)(395) = 335.75 + 395x/100 = 335.75 + 3.95x, which is too much.
D) works; simplifying the expression from A, we have 395(0.85) + 395(0.0085x) = 335.75 + 3.3575x.

Svetach [21]

Answer:

Option B. 11.78\ in^{3}

Step-by-step explanation:

we know that

The volume of a cone is equal to

V=\frac{1}{3} \pi r^{2}h

we have

r=1.5\ in

h=5\ in

substitute

V=\frac{1}{3} \pi (1.5)^{2}(5)

V=3.75\pi\ in^{3}

assume

\pi =3.14

V=3.75(3.14)=11.78\ in^{3}
