Answer:
x = 5
, y = -1
Step-by-step explanation:
Solve the following system:
{4 y + x = 1 | (equation 1)
5 y + 3 x = 10 | (equation 2)
Swap equation 1 with equation 2:
{3 x + 5 y = 10 | (equation 1)
x + 4 y = 1 | (equation 2)
Subtract 1/3 × (equation 1) from equation 2:
{3 x + 5 y = 10 | (equation 1)
0 x+(7 y)/3 = -7/3 | (equation 2)
Multiply equation 2 by 3/7:
{3 x + 5 y = 10 | (equation 1)
0 x+y = -1 | (equation 2)
Subtract 5 × (equation 2) from equation 1:
{3 x+0 y = 15 | (equation 1)
0 x+y = -1 | (equation 2)
Divide equation 1 by 3:
{x+0 y = 5 | (equation 1)
0 x+y = -1 | (equation 2)
Collect results:
Answer: {x = 5

Answer:
Step-by-step explanation:
1) the 3 measures of central tendency is mean, median, and mode.
So when finding the average clutch size is by using mean.
Clutch sizes:
114, 103, 121, 118, 107, 103, 104
114+103+121+118+107+103+104
=770
= 770 ÷ 7 ( 7 ⇒ there are seven numbers in total)
= 110
∴ Therefore the average clutch size is 110.
2) Through that table of data, yes, I think that the clutch size influences the survival rates of the offspring because it seems that when the clutch size is big, it is more likely for offspring to survive and return. Yet when the clutch size are small, for example, site E and G, the amount of turtles who returned are 40 and 38. But in site A, C, and D, there are 45 turtles in site A that returned, 55 turtles in site C, and 53 turtles in site D.
3) Possibly is because their clutch sizes are the smallest which made them unnoticeable to predators and more likely to survive and returned.
A sextant<span> is a </span>doubly reflecting navigation instrument<span> that measures the </span>angular distance<span> between two visible objects. The primary use of a sextant is to measure the angle between an </span>astronomical object<span> and the </span>horizon<span> for the purposes of </span>celestial navigation<span>.
The estimation of this angle, the altitude, is known as </span>sighting<span> or </span>shooting<span> the object, or </span>taking a sight<span>. The angle and the time when it was measured, can be used to calculate a </span>position line<span> on a nautical or aeronautical </span>chart. F<span>or example; sighting the </span>Sun<span> at </span>noon <span>or </span>Polaris<span> at night (in the Northern Hemisphere) to estimate </span>latitude<span>. Sighting the height of a landmark can give a measure of </span>distance off<span> and held horizontally.
A sextant can measure angles between objects for a </span>position on a chart.<span> A sextant can also be used to measure the </span>lunar distance<span> between the moon and another celestial object (such as a star or planet) in order to determine </span>Greenwich Mean Time<span> and hence </span>longitude<span>.

Answer:
A
Step-by-step explanation:
Given the solutions of a quadratic, say x = a, x = b then the factors are
(x - a) and (x - b) and the function is the product of the factors, that is
f(x) = (x - a)(x - b)
Here the solutions are x = 5 and x = - 1, thus the factors are
(x - 5) and (x - (- 1)), that is (x - 5) and (x + 1), thus
f(x) = (x - 5)(x + 1) → A
