Rewrite in slope-intercept form, y = mx + b, so that you can compare the slopes.

y = 4x + 6 m = 4

- 15x + 3y = - 45
add 15x to each side
3y = 15x - 45
divide both sides by 3
y = 5x - 15 m = 5

No, the slopes are different.

1. Perimeter
22a + 2(6a + 8) -4 = p

[I got 22a from 12a + 10a]

2. If p = 250, what is a?

22a + 2(6a + 8) - 4 = 250
Distributive property
22a + 12a + 16 - 4 = 250
Add like terms
34a + 12 = 250
Subtract 12 by both sides
34a = 238
Divide 34 by both sides
a = 7

If you have two horse pastures, one is. 25 feet by 45 feet and the other is 40 feet by 60 feet, what is the perimeter of the two

svp [43]

One field is 25 + 45 + 25 + 45 = 140 feet
Second field is 40 + 60 + 40 + 60 = 200 feet.
Therefore, all together, the two fields are 340 feet in perimeter together

Answer:

Total number of marbles = 12

P (1 red & 1 orange) =

$\frac{1 + 1}{12} \\ = \frac{2}{12} \\ = \frac{1}{6} \\ = 0.16$
