S= zh - 2zt^3 solve for z

Mathematics

Answer:

z = \frac{s}{h-2t^3}

Step-by-step explanation:

Given

s = zh - 2zt³ ← factor out z from each term

s = z(h - 2t³ ) ← divide both sides by h - 2t³

\frac{s}{h-2t^3} = z

Hi ;-)

s=zh-2zt^3\\\\z(h-2t^3)=s \ \ /:(h-2t^3)\\\\z=\dfrac{s}{h-2t^3}

Which function describes this table of value x -8, -4, 4, 8, y -2, 0, 4, 6
nadezda [96]

we conclude that the linear equation represented by the given table is:

y = (1/2)*x + 2

<h3>Which function is the one described by the table?</h3>

A general linear equation is given by:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through (x₁, y₁) and (x₂, y₂), then the slope is given by:

a = \frac{y_2 - y_1}{x_2 - x_1}

Here we can use just the first two points on the given line:

(-8, -2) and (-4, 0)

Then the slope will be:

a = \frac{0 - (-2)}{-4 -(-8)}  = \frac{2}{4} = \frac{1}{2}

Then the linear equation is something like:

y = (1/2)*x + b

To find the value of b, we can use one of the two given points, I will use (-4, 0), then:

0 = (1/2)*(-4) + b

0 = -2 + b

2 = b

Then we conclude that the linear equation represented by the given table is:

y = (1/2)*x + 2

Then the correct option is the first one.

Step-by-step explanation:

x is the number of weeks

Nathans account is as follows

2x+30

(2 dollars a week plus the 30 dollars already there)

Olivia's account is as follows

4x+15

(4 dollars per week plus the 15 already in there)

Fill in the blank by performing the indicated elementary row operation(s).
Scilla [17]

In this question, we are given a matrix, and we have to perform the given operation.

The matrix is:

\left[\begin{array}{ccc}6&-1&|5\\1&-5&|0\end{array}\right]

The following operation is given:

R_1 \rightarrow -6R_2 + R_1

In which R_1 is the element at the first line and R_2 is the element at the second line.

Updating the first line:

R_{1,1} = -6*1 + 6 = 0

R_{1,2} = -6*-5 - 1 = 30 - 1 = 29

R_{1,3} = -6*0 + 5 = 5

Thus, the filled matrix will be given by:

\left[\begin{array}{ccc}0&29&|5\\1&-5&|0\end{array}\right]
