Answer: 20y - 7.5
(3 - 8y) * (-2.5)
(3 * -2.5) + (-8y * -2.5)
-7.5 + 20y
20y - 7.5
The Shang Dynasty had several contributions to history. One of the most important and notable contribution was writing.
Answer:
After 16 months there will be a population of 1,944 insects.
Step-by-step explanation:
Since an insect population triples every 4 months, if the population started out with 24 insects, to determine how many insects would there be in 16 months, the following calculation must be performed:
X = 24 x 3 ^ (16/4)
X = 24 x 3 ^ 4
X = 1,944
Thus, after 16 months there will be a population of 1,944 insects.
Answer:
y - 5 = 1/4 (x - (-1))
Step-by-step explanation:
Since we have a parallelogram, then WX and YZ must be parallel
mathematically, the general equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
if two lines are parallel, the value of their slopes is same
for the first line, we have;
y = 1/4x - 6
The slope of the first line is 1/4
this is the slope of the second line too
By using;
y-y1 = m(x-x1)
where (x1,y1) is the point on the line
we have;
y - 5 = 1/4 (x - (-1))
11x2=22
22x6=132
I believe the answer is 132
