What are simultaneous linear equations?

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,

Given system of equation

y=x+2 - - - - -(1)

y=4x+23 - - - - (2)

From above equations,
x + 2 = 4x + 23
x = -7

Now,
y = -7 + 2
y = -5

Thus, the required solutions of the given system of equations is x = -7 and y = -5.

Write an inequality relating NM and NL-
NM < NL

Answers

Answer:

NM > LN

Step-by-step explanation:

Here, we want to write an inequality

we should beat it in mind that, the greater the angle that a side of a triangle faces, the greater its length will be relatively

as we can see, the side NM faces the greater angle of 83, relative to the side LN that faces the angle of 56;

So we can conclude that;

create a polynomial in the form ax^3+bx^2+cx=0 that has solutions of x=0,x=-5 and x=11, where a=3

Answers

3x^3-18x^2-165x=0

Since we are given the solutions, we can rewrite them.

x=-5 is (x+5)

x=11 is (x-11)

x=0 is just x

Now we can write our equation:

3x(x+5)(x-11)=0

*3 comes from the a being 3

Now we multiply, I’d recommend starting by using FOIL on the last two first and getting;

3x(x^2-6x-55)=0

Then distribute the 3x:

3x^3-18x^2-165x=0

No; a range value has two domain values.

Answers

Answer:

Yes; there is only one range value for each domain value.

Step-by-step explanation:

For a relation to be a function, every input, x-value, needs to have a unique output, y-value. This means that one x-value cannot have multiple y-values. So, in a function x-values will never repeat. Since x-values do not repeat in this relation, it is a function.

A website received 2500 registered members in July. And the number of registered members in August decreased to 2245. What was the percentage decrease in the number of registered members?

Answers

Number of registrations a website received during July = 2500

Number of registrations a website received during August = 2245

Number by which the registrations decreased :

[tex] =\tt 2500 - 2245[/tex]

[tex] =\tt 255[/tex]

Thus, the registrations decreased by 255.

Let x be the perrcentage of decrease.

Which means :

[tex] =\tt 255 = \frac{x}{100} \: of \: 2500[/tex]

[tex] = \tt255 = \frac{x \times 2500}{100} [/tex]

[tex] =\tt 255 = \frac{2500x}{100} [/tex]

[tex] = \tt255 \times 100 = 2500x[/tex]

[tex] = \tt25500 = 2500x[/tex]

[tex] =\tt \frac{25000}{2500} = x[/tex]

[tex]\color{plum} =\tt \bold{10.2\%}[/tex]

▪︎Thus, the percentage of decrease in the number of registered members = 10.2%

Find the value of the variable(s). If your answer is not an integer, leave it in simplest radical form.
x=10/3 x=10,y=30/3 x=30.y=10/3

Answers

Answer:

Use the fact that sin(x) = opp/hyp and tan(x) = opp/adj

where opp=opposite, hyp=hypotenuse, adj=adjacent and recall sin(30)=1/2 and tan(30) = 1/sqrt(3)

sin(30) = 1/2 = 17/y

y = 17(2) = 34

tan(30) = 1/sqrt(3) = 17/x

x = 17sqrt(3)

So the answer is (d)

Note that you could have also use the Pythagorean theorem to find x instead of using tan(30).

Answers

Answer:

50y + 75x ≥ 1000 ;

50(15) ≥ 750;

x ≥ 4

y ≥ 15

Step-by-step explanation:

Given that :

Number of stickers sold = y

Cost of sticker = 50

Cost of bag tag = 75

Number of bag tags sold = x

Total worth of items sold ≥ 1000

50y + 75x ≥ 1000

2.)

To make atleast 15 stickers

y ≥ 15

Atleast 15 stickers :

50(15) ≥ 750

3.)

A possible solution :

50(15) + 75(x) ≥ 1000

750 + 75x ≥ 1000

75x ≥ 250

x ≥ 3.33

x ≥ 4

y ≥ 15
