Answer:
False
Step-by-step explanation:
The equation x = c represents the equation of a vertical line parallel to the y- axis.
The equation y = c represents the equation of a horizontal line parallel to the x- axis
In both cases c is a constant
Hence x = - 2 is not parallel to the x- axis
Answer:
Speed of hikers are 4.4 mph and 7.7 mph
Step-by-step explanation:
Two hikers are 55 miles apart and walking towards each other.
They meet after 10 hours.
Let the speeds of hikers are S and S' mph.
One hiker walks 3.3 mph faster than the other,
S = 3.3 + S'
S' = S - 3.3
Distance traveled by the hiker with higher speed S = Speed × Time


Distance traveled by the slower hiker
= (S - 3.3) × 10
Total distance between them = 55 miles

10S + 10(S - 3.3) = 55
20S - 33 = 55
20S = 88
S = 4.4 mph
Speed of first hiker = 4.4 mph
Speed of second hiker = 4.4 + 3.3 = 7.7 mph
<span>The correct answer is 12/17m+30/17 yellow ribbons.
Explanation:
Setting up a proportion to represent the ratio of red to yellow, we have
r/y = 17/6.
Cross multiply:
6r=17y.
To isolate y, cancel 17 by dividing:
6r/17 = y, or (6/17)r=y.
Substituting 2m+5 for r, we have
(6/17)(2m+5)=y.
Use the distributive property:
(6/17)*2m+(6/17)*5=y
(12/17)m+30/17=y.</span>
Answer:
B) 
Step-by-step explanation:
We want to simplify ![\sqrt[3]{-125n^{12}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-125n%5E%7B12%7D%7D)
![\sqrt[3]{-125n^{12}} = \sqrt[3]{-1 * - 1 * -1 * 5 * 5 * 5 * n^4 * n^4 * n^4} \\\\= \sqrt[3]{(-1)^3 * 5^3 * (n^4)^3}\\\\= -1 * 5 * n^4\\\\= -5n^4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-125n%5E%7B12%7D%7D%20%3D%20%5Csqrt%5B3%5D%7B-1%20%2A%20-%201%20%2A%20-1%20%2A%205%20%2A%205%20%2A%205%20%2A%20n%5E4%20%2A%20n%5E4%20%2A%20n%5E4%7D%20%5C%5C%5C%5C%3D%20%5Csqrt%5B3%5D%7B%28-1%29%5E3%20%2A%205%5E3%20%2A%20%28n%5E4%29%5E3%7D%5C%5C%5C%5C%3D%20-1%20%2A%205%20%2A%20n%5E4%5C%5C%5C%5C%3D%20-5n%5E4)
