Answer:
y = -x - 2
this is because the <em>m </em> is the slope and the <em>b </em>is the intersection of the y axis
False , it would be positive
Answer:
for the first one it is
ED= 26
CF= 13
mED= 136
mHD= 68
mCE= dont know this one but the other ones im positive their right

Answer:
The cost of 1 videotape = $ 3.4
Step-by-step explanation:
Let us assume the cost of each cassette tap = $ m
So, the cost of each videotape = 2 x ( Cost of 1 cassette) = 2 x m = 2 m
Now, the cost of 3 cassette tap = 3 x ( Cost of 1 cassette) = 3 x m = 3 m
Also, the cost of 5 videotape = 5 x ( Cost of 5 videotape) = 5 x (2m) = 10 m
So, the cost of 3 cassette tap + 5 videotape = 3 m + 10 m
Also, given 3 blank cassette tapes and 5 blank videotapes costs $22.10 .
⇒ 3 m + 10 m = $22.10
or, 13 m = 22.10
⇒ m = 22.10/13 =1.7
or, m = $1.7
Hence, the cost of 1 cassette = m = $1.7
And, the cost of 1 videotape = 2 m = 2x ($1.7) = $ 3.4
Answer:
X=10
X=-8
Step-by-step explanation:
(x+1)*(x-3)=77
x²-3x+x-3=77
x²-2x-3=77
x²-2x-3-77=0
x²-2x-80=0
(x-10)*(x+8)=0
x-10 = 0
x=10
x+8=0
X=-8
