what does n mean in -10(n-5)=40

Step-by-step explanation:

1. First divide by the leading term, making the polynomial monic.

2. Then, given x

2 + a1x + a0, substitute x = y − a1  to obtain an equation without the linear term.

(This is the “depressed” equation.)

3. Solve then for y as a square root. (Remember to use both signs of the square root.)

4. Once this is done, recover x using the fact that x = y − a1

Answer:

2 <= x < 8

Step-by-step explanation:

2 is less than or equal to x and the symbol for that is <=

the least number should also be on the left side

8 is greater than x so the symbol is <

8 is the biggest number and goes on the right

Answer:

I have difficulty understanding the question.  I read it as "What is the value of  a number that when multiplied by 0.3 times (8/4) is equal to 34.55.  This doesn't seem correct, but if it is:

Step-by-step explanation:

(0.3)*(8/4)x = 34.55

(8/4)x = 115.17

x = (4/8)*(115.17)

x = 57.58

21 is the correct answer.

Answer:

1

Step-by-step explanation:

First, we read the notation from right to left, so let's reflect the point M first across the y-axis. Point M would be at the coordinates (5,-1)

Then, let's use translation to move point M left 4 and up 3, Point M will be at (2,1) so the x-value of the Point M is 1.

Hope this is useful.

Answer:

They are proportional

Step-by-step explanation:

Proportionality:

They are proportional because the cost is going up by 10 the entire time and the hours rented is going up by 2 the entire time.

Graphing:

Go to the 2 on the x-axis (horizontal line)

Go up to the 20 on the y-axis (vertical line)

The points to graph are:

(2,20)

(4,30)

(6,40)

(8,50)

I put a pic of what your graph should look like below!

Answer:

To plot the graph put the hours along the x axis and the cost on the y axis. Its a positive realationship because when the hours go up the cost goes up to, it isn't proportional because both values don't go up at the same rate.

Answer:

The 1st one on the right is a function

Answer:

Parabola Graph (top-right)

Step-by-step explanation:

A graph represents a function given that none of the x-coordinates have more than one corresponding y-coordinates. Consequently, if a graph contains two or more different points with the same x-coordinate, then that graph does not represent a function.  

An easier way of finding out whether a graph represents a function is through the vertical line test. In order to perform the vertical-line test, imagine dragging a ruler held vertically across the graph from left to right. A graph is a function if the edge of the ruler crosses the graph only once for every x -value.  

Out of all the given options, the graph of an upward-facing parabola represents a function (top-right graph), as each vertical line contains only one point. Please see the attachment, where I performed the vertical line test.

Answer:

Parallel

Step-by-step explanation:

Solving the equations, we come out to:

A. y = 1/4x + 1

B. y = 1/4x - 1

This would make the lines Parallel because the slope is the same

Answer:

It says in ascending order, and I don't think exponents will work.

Step-by-step explanation:

I think the correct answer would be 3 x 3 x 7, or 3² x 7

The only mistake that I can see is that it is not in ascending order.

If not, then write it as 3*3*7 or 3^2*7

Answer:

Slope = 3

Step-by-step explanation:

The formula to find the slope of a graph using two points is:

m = Δy/Δx

where m is the slope

We can start off by choosing two points on the graph. Two easy ones to pick out would be (6,30) and (1,15). Notice that the 15 and the 30 are y-coordinates and the 6 and the 1 are x-coordinates. To find the slope we will do

m = Δy/Δx = (30-15)/(6-1)

= 15/5

= 3

Thus the slope of this graph is 3

Answer:

d

Step-by-step explanation:

the first term is 8x. 8 is the coefficient and x is the base. so the answer is 8.

There are 30 adults in the swimming pool.

The ratio is a quantitative approach that shows the relation between two proportions.

From the given relation, the ratio of of the children to adults = 8 : 3

The total number of the ratio = 8 + 3 = 11

Given that there are 110 people in the population.

The number of adults that are there will be:

[tex]\mathbf{=\dfrac{3}{11}\times 110}[/tex]

= 30 adults

Answer:

  A = 2r²

Step-by-step explanation:

A square is a rhombus with equal-length diagonals. A square inscribed in a circle has diagonals equal to the diameter of the circle: 2r.

The area of a rhombus is half the product of the lengths of its diagonals. Hence the area of our square is ...

  A = (1/2)(2r)(2r)

  A = 2r²

Answer:

2

Step-by-step explanation:

r=1/2s[tex]\sqrt{2}[/tex]

2r=s[tex]\sqrt{2}[/tex]

2r/[tex]\sqrt{2}[/tex]=s remove [tex]\sqrt{2}[/tex] denominator by multiplying with [tex]\sqrt{2}[/tex]/[tex]\sqrt{2}[/tex]

Step-by-step explanation:

For each listed root x=p as signified by f(p) = 0, the function has a factor (x-p). The given roots and the given end behavior tell us the factored form is ...

  f(x) = -(x +3)(x +1)(x -1)(x -3)

The graph is attached. It shows the function increasing at extreme left, crossing the x-axis at x=-3, and again at x=-1, x=1 and x=3. Since it crosses an even number of times, the right-side end behavior is "decreasing" toward negative infinity.
