Answer:
3
Step-by-step explanation:
(x₁ , y₁) = (-1 , -2) & (x₂ , y₂) = (3 , 10)

![= \frac{10-[-2]}{3-[-1]}\\\\=\frac{10+2}{3+1}\\\\=\frac{12}{4}\\\\=4](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B10-%5B-2%5D%7D%7B3-%5B-1%5D%7D%5C%5C%5C%5C%3D%5Cfrac%7B10%2B2%7D%7B3%2B1%7D%5C%5C%5C%5C%3D%5Cfrac%7B12%7D%7B4%7D%5C%5C%5C%5C%3D4)
m = 4
y - y₁ = m (x - x₁)
y - [-2] = 4(x - [-1])
y + 2 = 4(x + 1)
y + 2 = 4x + 4
y = 4x + 4 - 2
y = 4x + 2
Answer:
(9,21)
Step-by-step explanation:
If you plug in all the pairs, the only one that is true is (9,21).
y=x+12
21=9+12
The above equation is true, and that is why (9,21) is the answer.
Hope this helped! :)
16 - 12x = 4y
First, divide both sides by 4. / Your problem should look like: \frac{16-12x}{4} = y
Second, factor out the common term 4. / Your problem should look like: \frac{4(4-3x)}{4} = y
Third, cancel 4. / Your problem should look like: 4 - 3x = y
Fourth, switch sides. / Your problem should look like: y = 4 - 3x
Answer: y = 4 - 3x
Answer:
Poission Ratio = 0.2784
Step-by-step explanation:
we know that
Poission ratio is defined as
μ = 
We also know that lateral strain =
In our case
Final width = 2.89945 in
Initial width = 2.9 in (Area of cross section (width x depth) = 2.9 in x 2.9 in)
Thus lateral strain = 
Lateral strain = 
Similarly longitudinal strain = 
Thus longitudinal strain = 
Longitudinal strain = 
Thus by formula poission ratio = 
Poission Ratio = 0.2784
Answer:
39°
Step-by-step explanation
I’m pretty sure this is 39° because of the interior angle theorem.
