(2,2)(-2,-4)
slope = (-4 - 2) / (-2 -2) = -6/-4 = 3/2. the slope of this line is 3/2. A parallel line will have the same slope
y - y1 = m(x - x1)
slope(m) = 3/2
(-3,1)...x1 = -3 and y1 = 1
now we sub
y - 1 = 3/2(x - (-3)....not done yet
y - 1 = 3/2(x + 3) <=== its the last one
Let's use f(x) for the first one and g(x) for the second.
n is the number of songs downloaded, t is the time in years, and m is the time in months.
f(x) = 125t + 10m
g(x) = 50 + n
For 2, substitute 1 for t and 12 for m.
For 4, solve f(x) = g(x).
For 5, solve g(x) for n=(14*12). Compare it to the value of f(x) for t=1 and 12=m.
Hello from MrBillDoesMath!
Answer:
152 in^2
Discussion:
Surface area =
2 (area of side triangle + area of rectangle face) +
area of bottom rectangle
= 2 ( (1/2) 6*4 + 5*8 ) + 8*6
= 2 ( (1/2) 24 + 40 ) + 48
= 2 (12 +40 ) + 48
= 2(52) + 48
= 104 + 48
= 152
Thank you,
MrB
So heterozygous means one dominant trait and one recessive trait (Ll). Homozygous is either 2 recessive traits or 2 dominat. (in this case ll).
1.)Genotype: Ll and ll
Phenotype: 50% chance of Long pea plant, 50% chance of short.
2.) Genotype: Ww (widows peak) and ww (no widows peak)
Phenotypes: 75% chance of widows peak and 25% of no widows peak.
3.) Genotype: BB and Bb
Phenotype: 100% chance of black
