What is the equation of the line shown in the graph?

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%

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).

Step-by-step explanation:

12x + 15 = 3(4x + 5)

Ok so basically if an input (x) has more than one output (y) it is NOT a function. One output having more than one input is okay though.

So G) is a function, bc for every x there is just 1 y

H) is not a function

I) is not a function either

Then the 6 below ( i can't read their numbers so they're just gonna be 1-6, top 3 from left to right then the bottom three from left to right)

2. not a function

3. function

4. function

5. not a function

6. not a function

i might be wrong, but i hope this helps!

Answer:

Answer:

option b

Step-by-step explanation:

21/48 reduced to it's lowest term is 7/16 and solving option b... 7/12 ×3/4 3 would divide 12 to give 4 and multiply what you have left which is 7/4 ×1/4 would be equal to 7/16

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

Answer:

mark me branlist and if anyone help me with my question from my profile would be appriciate.

Answer:

Step-by-step explanation:

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

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.

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;
