Answer:
8x= y
Step-by-step explanation:
from what a can see the line passes through the point (10,80) meaning for every 10 x there is 80y
so you can just divide 80 by 10

Let c be the ounces of clay that Elisa used. For small vases, the value of c should be less than or equal to 4.5 which can mathematically be expressed as c ≤ 4.5. For large vases, the value of c should be greater than or equal to 12, c ≥ 12. Thus, the answer to this item is letter D.
Unit rate of 1st Can = 1.14/8 = $0.1425
Unit rate of 2nd Can = 1.75/12 = $0.145
1st Can is cheaper than 2nd one
Answer:
( √15 + 8)/7
Step-by-step explanation:
TanA = -√15
.we are to find tan(A-π/4).
In trigonometry
Tan(A-B) = TanA - TanB/1+ tanAtanB
Hence:
tan(A-π/4) = TanA - Tanπ/4/1+ tanAtanπ/4
Substitute tan A value into the formula
tan(A-π/4) = -√15-tanπ/4 / 1+(-√15)(tanπ/4
tan(A-π/4) = -√15-1/1-√15
Rationalize
-√15-1/1-√15 × 1+√15/1+√15
= -√15-√225-1-√15/(1-√225)
= -2√15-15-1/1-15
= -2√15 -16/(-14)
= -2(√15+8)/-14
= √15 + 8/7
Hence the required value is ( √15 + 8)/7
