if you look at delta y over x, you'll notice it always equals 2
i.e (22-2)/10-0 = 20/10 = 2
or (14-2)/6-0 = 12/6 = 2
or even (22-8)/10-3 = 14/7 = 2
This means that m (slope) is 2.
Now as for b. b is the y intercept and that value occurs when x = 0. On the table, when x = 0 y = 2 so b = 2.
y = mx + b becomes
y = 2x + 2
Answer:
62.8 inches
Step-by-step explanation:
✓We can determine the
Circumference of the wheel of the bicycle using the expression below;
Circumference= (πd) ...........eqn(1)
Where d= diameter = 20inches
If we substitute the value of " diameter" into eqn(1)
Circumference = (π × 20)
= 62.8inches
(Where π= 3.142)
Therefore, measurement that is closest to the circumference of the wheel is 62.8inches
For this case we have the following expression:
![a + b-c-d](https://tex.z-dn.net/?f=a%20%2B%20b-c-d)
We must evaluate the expression when:
![a = 27\\b = 26\\c = 27\\d = 23](https://tex.z-dn.net/?f=a%20%3D%2027%5C%5Cb%20%3D%2026%5C%5Cc%20%3D%2027%5C%5Cd%20%3D%2023)
Substituting the values we have:
![a + b-c-d = 27 + 26-27-23](https://tex.z-dn.net/?f=a%20%2B%20b-c-d%20%3D%2027%20%2B%2026-27-23)
Equal signs are added and the same signs are placed.
![a + b-c-d = + 53-50](https://tex.z-dn.net/?f=a%20%2B%20b-c-d%20%3D%20%2B%2053-50)
Different signs are subtracted and the sign of the major is placed:
![a + b-c-d = 53](https://tex.z-dn.net/?f=a%20%2B%20b-c-d%20%3D%2053)
Finally we have to:
![a + b-c-d = 53](https://tex.z-dn.net/?f=a%20%2B%20b-c-d%20%3D%2053)
Answer:![a + b-c-d = 53](https://tex.z-dn.net/?f=a%20%2B%20b-c-d%20%3D%2053)
