Answer:
1.2 * 10^3
Step-by-step explanation:
3.12 * 10^8
=========
2.6 * 10^5
Start by doing 3.12 / 1.6 = 1.2 and that is the correct number of sig digs.
Now get the power on the 10. When dividing, the powers subtract.
10^(8 - 5)
10^ 3
The answer is 1.2 * 10^3
Let point A be
and point B ![(-1, -8)](https://tex.z-dn.net/?f=%28-1%2C%20-8%29)
![m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-8 - (-6)}{-1 - 2} = \frac{-8 + 6}{-1 -2} = \frac{-2}{-3} = \frac{2}{3}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D%20%3D%20%5Cfrac%7B-8%20-%20%28-6%29%7D%7B-1%20-%202%7D%20%3D%20%5Cfrac%7B-8%20%2B%206%7D%7B-1%20-2%7D%20%3D%20%5Cfrac%7B-2%7D%7B-3%7D%20%3D%20%5Cfrac%7B2%7D%7B3%7D)
Use the point-slope formula and whichever point you want as , in this case I'll use
![y - y_1 = m(x - x_1)\\y - (-6) = \frac{2}{3}(x - 2)\\y + 6 = \frac{2}{3}x - \frac{4}{3}\\y = \frac{2}{3}x - \frac{4}{3} - 6\\y = \frac{2}{3}x - \frac{14}{3}](https://tex.z-dn.net/?f=y%20-%20y_1%20%3D%20m%28x%20-%20x_1%29%5C%5Cy%20-%20%28-6%29%20%3D%20%5Cfrac%7B2%7D%7B3%7D%28x%20-%202%29%5C%5Cy%20%2B%206%20%3D%20%5Cfrac%7B2%7D%7B3%7Dx%20-%20%5Cfrac%7B4%7D%7B3%7D%5C%5Cy%20%3D%20%5Cfrac%7B2%7D%7B3%7Dx%20-%20%5Cfrac%7B4%7D%7B3%7D%20-%206%5C%5Cy%20%3D%20%5Cfrac%7B2%7D%7B3%7Dx%20-%20%5Cfrac%7B14%7D%7B3%7D)

Answer:
12
Step-by-step explanation:
×12+8
Answer:
12
Step-by-step explanation:
Let's put the equations in standard form. For the first equation, we have:
−11y=6(z+1)-13y
2y−6z=6
y−3z=3
The second equation is:
4y−24=c(z−1)
4y−cz=24−c
If we multiply the first equation by 4, we get:
4y-12z=12
Comparing the two equations, we see that if c=12, both equations will be the same and there will be infinitely many solutions.
The correct value of c is 12.
