See attachment of the graph of the points on the coordinate plane.

<h3>What are linear equations?</h3>

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

<h3>How to determine the graph of the points on the coordinate plane.?</h3>

A system of linear equations is a collection of at least two linear equations.

In this case, the points are given as

(7, 3) and (1, 5)

The point (7, 3) means that:

x = 7 and y = 3

i.e. the point is located 7 units to the right of the origin and 3 units up the origin

Similarly,

The point (1, 5) means that:

x = 1 and y = 5

i.e. the point is located 1 unit to the right of the origin and % units up the origin

Next, we plot the points on the coordinate plane.

Let's assume the question is to find the area of the shaded region.

7. We have to assume the bottom right angle is right as well.

Consider the white triangle at the bottom; call its left leg x.

Then the big tra pezoid which includes the shaded part has area

(1/2)((14 + x) + 26)(15)

and the bottom right triangle has area

(1/2)x(15)

and white triangle on the right has

(1/2)(26)(15 - 6)

The total area of the shared part is thus

(1/2)((14 + x) + 26)(15) - (1/2)x(15) - (1/2)(26)(15 - 6)

= (1/2)(15)(40 + x - x) - 13(9)

= 183

Answer: 183 sq in

8. That's an annulus, the difference between two circles. The outer one has radius 21/2 m, the inner one radius 21/2 - 3.5.

A = πR²-πr² = π( (21/2)² - (21/2 - 3.5)² ) = π(2(21/2)(3.5) - 3.5²) = 3.5π(21-3.5)=61.25π

Answer: 61.25π sq m

9. That looks like a parallelogram less a right triangle.

The parallelogram has area 15(23.8)

The right triangle missing leg x satisfies

x² + 21² = 23.8²

x = 11.2

The right triangle area is

(1/2) (21)(11.2)

So the shaded area is

15(23.8) - (1/2) (21)(11.2) =239.4

Answer: 239.4 sq ft

10. That's a circle less a square. The diagonal of the square is 8√2 and the radius of the square is half of that, 4√2

The area is

π(4√2)² - 8² = 32 π - 64

Answer: 32π - 64 sq cm

Solve rx = 30 for x.

yan [13]

X= 30/r is the answer because if you divide both sides by r you are left with x=30/r because you cant divide 30 by r

A play has tickets available for 8 orchestra seats and 12 balcony seats. The next person to buy a ticket will be randomly assign

qaws [65]

The probability that the next person will be assigned an orchestra seats is 2/5.

<h3>What is Probability?</h3>

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Here, Available Orchestra seats = 8

Balcony seats = 12

Total available seats = 12 + 8 = 20

Probability = Favorable Outcome / Total Outcome

Probability of getting orchestra ticket = 8/20

= 2/5

Thus, the probability that the next person will be assigned an orchestra seats is 2/5.

what abiotic factor is changing the ecosystem of Lake Washington,and how has this factor changed over time.

raketka [301]

Answer:

Step-by-step explanation:

Temperature is the abiotic factor that is changing the ecosystem. Both the top layer temperature and the overall temperature of the lake are increasing. The warmer temperatures have delayed the yearly springtime mixing of warm and cold water in the lake.
