Answer:
Eliminate y by adding equations (1) and (3) because the coefficients on y are opposites. Then eliminate y by multiplying equation (1) by 2 and adding it to equation (2). Eliminate z by subtracting equations (1) and (2) because the coefficients are the same. Then eliminate z by multiplying equation (3) by 2 and adding it to equation (1).

a canoe can be paddled at 7 mph through a placid lake the stream flows at 3 mph
Using system of linear equations the distance at the fisherman and the bobbler meets ls 8 miles
Speed in still waters = 7 mph
Stream speed = 3 mph
Upstream speed of canoe = 7 - 3 = 4 mph
Distance between fisherman and bobbler = 14 miles
Let seperation distance = d
Meeting distance = 14 - d
using the relation :
Distance= (speed × time)
canoe distance , d = 4t - - - - (1)
Noobler distance = 14 - d = 3t ----(2)
Equate (1) and (2)
d/4 = (14 - d)/3

the time take for the fisherman to meet the bobber is 2 hours
as given in the question ,
canoe being paddled at 7mph (at still water)
speed of the stream is 3mph
distance between the fisherman and the bobber is 14 miles
let the bobber and the canoe meet at a distance X
from the starting point of canoe.
then the distance of the meeting point from the fisherman is = (14 - X)
using the formula Distance = Speed x Time,
we have for the canoe,
D= 4T, ----- (1)
for the bobber, 14 - X = 3T ----- (2) ( speed of bobber = speed of stream= 3 MPH)
T is same in both equations, hence
=> [tex]\frac{X}{4} =\frac{14-X}{3}\\[/tex]

Based on the given matrix equation, the value of x and y are ±6 and 16 respectively.
How to determine the value of x and y.In order to solve for the value of x and y, we would create an equation from the upper and lower part of this matrix respectively.
x² - 4 = 32 ...........(upper part)
y + y - 4 = y + 6 ....(lower part)
Next, we would solve for x:
x² - 4 = 32
x² = 32 + 4
x² = 36
x = ±√36
x = ±6.
For the value of y, we have:
y + y - 4 = y + 6
2y - 4 = y + 6
2y - y = 6 + 10
y = 16.

a 15.8 g sample contains 3.6 g of f, 4.9 g of h, and 7.3 g of c. what is the percent composition of fluorine in this sample?
The percentage mass of Fluorine in the sample can be calculated using the ratio formula. Hence, the percentage composition of Fluorine is 22.78%
Total grams of sample = 15.8 grams Mass of Fluorine = 3.6 grams Mass of hydrogen = 4.9 grams Mass of carbon = 7.3 gramsThe percentage composition of Fluorine can be written thus :
(Mass of Fluorine ÷ total mass) × 100%Percentage composition = (3.6÷15.8) × 100%
Percentage composition = 0.2278 × 100% = 22.78%
Therefore, the percentage composition of Fluorine is 22.78%

Taking into account the definition od percentage composition, the percent composition of fluorine in this sample is 22.78%.
The Percentage Composition is a measure of the amount of mass that an element occupies in a compound and indicates the percentage by mass of each element that is part of a compound.
To calculate the percentage of composition, it is necessary to know the mass of the element in a known mass of the compound.
In this case, you know that a 15.8 g sample contains 3.6 g of F, 4.9 g of H, and 7.3 g of C.
Dividing the mass amount of F present in the compound by the mass of the sample and multiplying it by 100 to obtain a percentage value, the percentage composition of fluorine is obtained:
[tex]percentage composition of fluorine=\frac{3.6 grams}{15.8 grams} x100[/tex]
percentage composition of fluorine= 22.78%
Finally, the percent composition of fluorine in this sample is 22.78%.

describe one way an invasive species, such as the zebra mussel, can decrease the carrying capacity for a native species in an ecosystem.
The zebra mussel is an invasive species that decrease the carrying capacity of native species by competing for limited food resources. Invasive species are harmful to the homeostasis of an ecosystem.
The carrying capacity refers to the maximum population size of a species sustained by specific environmental conditions.
The factors that affect the carrying capacity include the availability of both biotic (e.g., food, presence of invasive species, etc) and abiotic (e.g., water, habitat) resources.
For example, Zebra mussels, and Quagga mussels are invasive species that can decrease the carrying capacity of native mussels by taking away limited food and attaching themselves to the native mussels.
