14
Step-by-step explanation:
40 plus 2 is 42
42 divided by 3 is 14
Answer:
x = -3
y = 9
Step-by-step explanation:
Add two equations up
4x + 5y - 9x - 5y = 33 - 18 add or subtract like terms
-5x = 15 divide both sides by -5
x = -3 we can use this information to find the value of y
4x + 5y = 33 replace x with -3
4 * (-3) + 5y = 33
-12 + 5y = 33 add 12 to both sides
5y = 45 divide both sides by 5
y = 9

Answer:
![\boxed{m = \frac{1}{4}}](https://tex.z-dn.net/?f=%5Cboxed%7Bm%20%3D%20%5Cfrac%7B1%7D%7B4%7D%7D)
.
Step-by-step explanation:
Use the form below
![\boxed{\boxed{m = \frac{y_2 - y_1}{x_2 - x_1} }}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cboxed%7Bm%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D%20%7D%7D)
Where
is a slope
and
are the point of the line
.
So, the slope is
![(2,~ 1) \to x_1 = 2~and~y_1 = 1](https://tex.z-dn.net/?f=%282%2C~%201%29%20%5Cto%20x_1%20%3D%202~and~y_1%20%3D%201)
![(6,~ 2) \to x_2 = 6~and~y_2 = 2](https://tex.z-dn.net/?f=%286%2C~%202%29%20%5Cto%20x_2%20%3D%206~and~y_2%20%3D%202)
.
![m = \frac{2-1}{6-2}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B2-1%7D%7B6-2%7D)
![m = \frac{1}{4}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
.
Happy to help:)
Just count the zeros at the left. In your case <span>6
</span> so your number equals <span><span>0.428⋅<span>10<span>−6</span></span></span>
</span> and in scientific <span>4.28⋅<span>10<span>−<span>7</span></span></span></span>
