I know i’m asking a lot of questions but help me please. Is this correct?

Answers

Answer 1

Answer:

Option A

Step-by-step explanation:

ok so firstly this is super duper easy! all you have to see first in these type of questions is the "sequence" or the "pattern". and you have to make a ittle equation with this, so the first picture has 1 square, secound one has 5, the third one has 9, and the fourth one has 13.

- so firstly see or find a specific sequence.

13 - 9 = 4

9 - 5 = 4

5 - 1 = 4

so we found out "4" is the main changing unit. Now lets make a short formula which will help us determine any number ahead of the picture.

so lets do 4x = number of squares, x= figure number

4(1) = 4 :: wrong, because the first figure has only one square

so, 4x - 3

4(1) - 3 = 1 :: correct! this euqation works!

Now, we need to find how many squared there are in figure 100, so ->

4(100) - 3 = 397 squares!

and now doing the question will be easier, because option A says 1 square in the centre and 99 sqaures on each side.

So-> 99 + 99 + 99 + 99 +1 = 397! boom!! got the answer!

Which statements are correct? Check all that apply.
The variable m is the independent variable.
The number of miles increases as time increases.
The number of hours causes a change in the number of miles ridden.
The variable h is the independent variable.
The variable h is the dependent variable.
The farther Mason rides, the less time it takes.
The variable m is the dependent variable.

Answers

Answer:

Step-by-step explanation:

I'm assuming that the variable m is miles. You have to make that clear. It makes any answerer on here a little cranky when we have to guess.

A: Wrong. The first statement is wrong. m is the dependent variable. Time is usually the independent variable as it is in this case.

B: True. That happens

C: True. Miles increases as time increases.

D: True. If h is hours then H is the independent Variable

E: is wrong. H cannot be both, and it is not the dependent variable

F: False: The further he rides, the more time it takes.

G: True: m is the dependent variable.

Correct Statements.

Complete the steps to solve the -19x - 11=-144

Answers

The correct answer is:X=7

Step-by-step explanation:

-19x - 11 = -144

collect like terms,

-19x = -144 + 11

-19x = -133

Divide both sides by the coefficient of x

-19x/-19 = -133/-19

-19 cross with -19 leaving x, negative cross with negative leaving 133/19

133÷19

Therefore, x = 7

Use the table below to write an equation in slope intercept form. How did you find the slope and the y intercept of the equation?

Answers

Answer:

y = 8x+9

Step-by-step explanation:

First find the slope

m = (y2-y1)/(x2-x1)

= ( 57-17)/(6-1)

= 40/5

= 8

The slope intercept form is y = mx+b where m is the slope and b is the y intercept

y = 8x+b

Substitute a point into the equation

33 = 8*3 +b

33 = 24+b

Subtract 24 from each side

33-24 = 24+b-b

9 = b

y = 8x+9

#equation

(1,7)(3,33)

Slope

m=33-17/3-1m=16/2m=8.

Now

y-y_1=m(x-x_1)y-17=8(x-1)y-17=8x-8y=8x+9

On comparing to slope intercept form

y intercept is 9

The axis of symmetry for a function in the form f(x) = x2 + 4x − 5 is x = −2. What are the coordinates of the vertex of the graph?

D) [tex](-2,-9)[/tex]

Step-by-step explanation:

Vertex Form of a Vertical Parabola:

[tex]y=a(x-h)^2+k[/tex]

Vertex -> [tex](h,k)[/tex]

Axis of Symmetry -> [tex]x=h[/tex]

Vertical Scale Factor -> [tex]a[/tex]

To turn [tex]f(x)=x^2+4x-5[/tex] into vertex form, we need to complete the square on the right sideTherefore, if [tex]f(x)=0[/tex], then [tex]0+9=x^2+4x-5+9[/tex] completes the square on the right side This becomes [tex]9=(x+2)^2[/tex]This means that our function in vertex form is [tex]f(x)=(x+2)^2-9[/tex]

Therefore, the vertex of the graph is [tex](h,k)=(-2,-9)[/tex].

The coordinates of the vertex of the graph is (-2, -9).

What are Quadratic Functions?

Quadratic functions are polynomial functions consisting of variables and exponents and the degree of the variable is 2.

The general form of a quadratic function is f(x) = ax² + b x + c.

Given is a quadratic function,

x² + 4x - 5

Given that axis of symmetry of the function is x = -2.

So the x coordinate of the vertex = -2.

y coordinates = f(-2) = 4 - 8 - 5 = -9

Hence the vertex is (-2, -9).
