Answer:
y=-3x+31
Step-by-step explanation:
y-y1=m(x-x1)
y-4=-3(x-9)
y-4=-3x+27
y=-3x+27+4
y=-3x+31
Answer:
360/100=3.6
30 x 3.6 = 108
10 x 3.6 = 36
From the 10 you can multiply by 5. 36 x 5 = 180
10 3.6 = 36
36 + 36 = 72. 108 + 72 = 180
180 + 180 = 360.
Angles are Red-108, Blue-36, Green-180, and yellow-36.

Step-by-step explanation:
Answer:
The common difference is -5/4
T(n) = T(0) - 5n/4,
where T(0) can be any number. d = -5/4
Assuming T(0) = 0, then first term
T(1) = 0 -5/4 = -5/4
Step-by-step explanation:
T(n) = T(0) + n*d
Let
S1 = T(x) + T(x+1) + T(x+2) + T(x+3) = 4*T(0) + (x + x+1 + x+2 + x+3)d = 240
S2 = T(x+4) + T(x+5) + T(x+6) + T(x+7) = 4*T(0) + (x+5 + x+6 + x+7 + x+8)d = 220
S2 - S1
= 4*T(0) + (x+5 + x+6 + x+7 + x+8)d - (4*T(0) + (x+1 + x+2 + x+3 + x+4)d)
= (5+6+7+8 - 1 -2-3-4)d
= 4(4)d
= 16d
Since S2=220, S1 = 240
220-240 = 16d
d = -20/16 = -5/4
Since T(0) has not been defined, it could be any number.
