It will show a negative linear correlation between x and y
45ft squared would be the answer i think because the carpet could be smaller or bigger than the area of the room or it wouldn't fit.
Answer:
x= 3, y= 4
Step-by-step explanation:
y= 3x -5 -----(i)
y= -x +7 -----(ii)
Substitute (i) into (ii):
3x -5= -x +7
3x +x= 7 +5
4x= 12
x= 12 ÷4 <em>(</em><em>÷</em><em>4</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
x= 3
Substitute x= 3 into (ii):
y= -3 +7
y= 4
0.25q + 0.10d = 1.25
q + d = 8....q = 8 - d
0.25(8 - d) + 0.10d = 1.25
2 - 0.25d + 0.10d = 1.25
-0.25d + 0.10d = 1.25 - 2
-0.15d = - 0.75
d = -0.75/-0.15
d = 5 <=== there are 5 dimes
q + d = 8
q + 5 = 8
q = 8 - 5
q = 3 <=== there are 3 quarters
Im sorry, I cant see what it is you want me to do??
