Hey there!
This is a pretty long equation, but don't let it confuse you- it's full of like terms.
Let's clean up the right side by adding the 4x and the 2x:
6x+2=3x-7
We can subtract 3x from both sides:
3x + 2 = -7
Subtract two to both sides to get:
3x = -9
Finally, divide both sides by 3 to get:
x = -3
Hopefully this helps!

Answer:
95% of women have pregnancies length between 236 and 300 days.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 268
Standard Deviation, σ = 16
We are given that the distribution of length of a human pregnancy is a bell shaped distribution that is a normal distribution.
Empirical Rule:
- It states that for a normal distribution all the data lies within three standard deviation of mean.
- About 68% of data lies within one standard deviation of mean.
- About 95% of data lies within two standard deviations of mean,
- About 99.7% of data lies within three standard deviation from mean.
P(pregnancies are between 236 and 300 days)
By empirical rule, 95% of data lies within two standard deviations of mean, thus, 95% of women have pregnancies length between 236 and 300 days.
H(x)=(-1/5)x(x-13(
h(x)=(-x/5)(x-13)
h(x)=(13x-x^2)/5
h(3)=(13*3-3^2)/5
h(3)=(39-9)/5
h(3)=30/5
h(3)=6 in
Y=-3x+1 because in the points the equation will be y+2=-3(x-1) this converted into slope intercept form is y=-3(x-1)
