PLEASE HELP, WILL MARK BRAINLIEST - Jessie graphed one of the lines in a system of equations: y=3x-2. If the system has an infin

ite number of solutions, which statements are true? CHECK ALL THAT APPLY (Not just one answer)
☐ Any point in the coordinate plane is a solution because it has an infinite number of solutions.

☐ Point (1, 1) is a solution because it is one of the points on the line already graphed.

☐ It is impossible to tell if (–1,–5) is a solution without seeing the other line graphed.

☐ Point (20, 58) is a solution because it results in a true statement when the point values are substituted into the equation of the line.

☐ When the other line in the system is graphed, it will share all points with the line already graphed.

Answer:

The correct options are 2, 4, 5.

Step-by-step explanation:

It is given that the system of equations has an infinite number of solutions. It is  possible when both equations represents the same line.

One of the lines in a system of equations:

y=3x-2

It means another line has same equation.

All the points lie on the line are the solution of the system of equations. So, option 1 is incorrect.

From the given graph it is clear that the point (1,1) lies on the line already graphed. So, the point (1, 1) is a solution and option 2 is correct.

Put x=-1 in the given equation.

y=3(-1)-2=-5

The point (-1,-5) is a solution. So, option 3 is incorrect.

Put x=20 in the given equation.

y=3(20)-2=58

The point (20,-58) is a solution. So, option 4 is correct.

Since both lines has same equation, therefore when the other line in the system is graphed, it will share all points with the line already graphed.  Option 5 is correct.

Answer:

inconsistent

Step-by-step explanation:

The two lines are parallel which means they will never intersect.  This means they have no solution.  When there is no solution they are inconsistent.


Coincident-  same line - infinite solutions

Inconsistent - parallel lines - no solutions

Consistent and independent  - 1 solutions

In ΔUVW, w = 44 cm, u = 83 cm and ∠V=141°. Find the area of ΔUVW, to the nearest square centimeter.
Tema [17]

Answer:

Area  \approx 1149\ cm^2

Step-by-step explanation:

<u>Given that:</u>

ΔUVW,

Side w = 44 cm, (It is the side opposite to \angle W)

Side u = 83 cm (It is the side opposite to \angle U)

and ∠V=141°

Please refer to the attached image with labeling of the triangle with the dimensions given.

Area of a triangle with two sides given and angle between the two sides can be formulated as:

A = \dfrac{1}{2}\times a\times b\times sinC

Where a and b are the two sides and

\angle C is the angle between the sides a and b

Here we have a = w = 44cm

b = u = 44cm

and ∠C= ∠V=141

Putting the values to find the area:

A = \dfrac{1}{2}\times 44\times 83\times sin141\\\Rightarrow A = \dfrac{1}{2} \times 3652 \times sin141\\\Rightarrow A =1826 \times 0.629\\\Rightarrow A  \approx 1149\ cm^2

So, the <em>area </em>of given triangle to the nearest square centimetre is:

Area  \approx 1149\ cm^2
