Answer:

$\dfrac{1-10}{8-5}$

Step-by-step explanation:

The average rate of change between two points on a graph is ...

average rate of change = slope = rise/run

The rise over the given interval is the function value at x=8 less the function value at x=5. That is, ...

rise = 1 - 10

The run is the difference in the x-values:

run = 8 - 5

Then the average rate of change is ...

average rate of change = rise/run = (1 -10)/(8 -5)

_____

Here, the points are written as (x, y), so the only pair we're interested in is ...

(5, 10) and (8, 1)

The vector 〈4,1〉 describes the translation of A(-1, w) to A'(2x+1,\ 4) and B(8y-1,1) onto B'(3,3z) . Find the values of w, x, y,

expeople1 [14]

The values of the variables associated ot translation operations are (w, x, y, z) = (3, 1, 0, 2 / 3).

<h3>How to determine the values of the variables associated to translation operations</h3>

Herein we find two translation cases of points set on Cartesian plane. Translations are rigid operations of the form:

P'(x, y) = P(x, y) + T(x, y)

Where:

P(x, y) - Original point
P'(x, y) - Resulting point
T(x, y) - Translation vector

Now we proceed to determine the values of the variables w, x, y, z behind each translation operation, substitute on each component and solve the resulting formula:

T(x, y) = A'(x, y) - A(x, y)

(2 · x + 1, 4) - (- 1, w) = (4, 1)

(2 · x + 2, 4 - w) = (4, 1)

(x, w) = (1, 3)

T(x, y) = B'(x, y) - B(x, y)

(3, 3 · z) - (8 · y - 1, 1) = (4, 1)

(4 - 8 · y, 3 · z - 1) = (4, 1)

(y, z) = (0, 2 / 3)

Tom is buying topsoil for the flower bed shown below. One bag of topsoil covers 15 square meters. How many bags of topsoil does

____ [38]

Answer:

We need 4 topsoils

Step-by-step explanation:

I think your question is missed of key information that is the area of the flower bed, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

The flower bed is a triangle with its height is 5 cm and the base length is 12 cm, so we need to find out the area of it:

S = Height*the base length = 5 * 12 = 60 $m^{2}$

So the bags of topsoil does Tom need to cover his flower bed is:

$\frac{Area of the flower bed}{The area of the topsoil }$ = $\frac{60}{15}$ = 4

We need 4 topsoils

What is the value of x? Also show work pls

drek231 [11]

Answer:

x = 34

Step-by-step explanation:

The angles are corresponding angles and corresponding angles are equal if the lines parallel

2x+3 = 71

Subtract 3 from each side

2x+3-3 = 71-3

2x = 68

Divide by 2

2x/2 = 68/2

x = 34

Write an equation to represent the following statement.

Stells [14]

Step-by-step explanation:

"Is" means equals. "Less than" means subtracted from.

28 = k - 12

Add 12 to both sides to solve for k:

k = 40

Which statement about the following equation is true? 3x2 â€"" 8x 5 = 5x2.

kati45 [8]

The discriminant is greater than 0, so there are two real roots and it can be determined by using nature of roots.

Given that,

Equation; $\rm 3x^2 - 8x + 5 = 5x^2$

We have to determine,

Which statement about the following equation is true?

According to the question,

To determine the true statement about the equation following all the steps given below.

Equation; $\rm 3x^2-8x+5=5x^2$

Simplify the equation for the roots of the equation,

$\rm 3x^2-8x+5=5x^2\\\\\rm5x^2- 3x^2+8x-5=0\\\\ 2x^2+8x-5=0\\\\ 2x^2+8x-5=0\\\\2x^2+8x=5\\\\2x(x+4)=5\\\\Then, \ 2x = 5, \ \ x = \dfrac{5}{2} \\\\And\ \ x+4=5, \ \ x=5-4, \ \ x=1$

The equation has two real roots and x is 1 and 5/2.

Hence, The discriminant is greater than 0, so there are two real roots.
