Answer:

z=7

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(z+6)−2=9z

(5)(z)+(5)(6)+−2=9z(Distribute)

5z+30+−2=9z

(5z)+(30+−2)=9z(Combine Like Terms)

5z+28=9z

Step 2: Subtract 9z from both sides.

5z+28−9z=9z−9z

−4z+28=0

Step 3: Subtract 28 from both sides.

−4z+28−28=0−28

−4z=−28

Step 4: Divide both sides by -4.

−4z/−4=−28/−4

z=7

Distribute, so 5z+28+9z, then subtract 5z, and you get 4z=28. Divide by 4 so x=7

What is most likely the correlation coefficient for the set of data shown shown
satela [25.4K]

Answer:

C) 0.19

Step-by-step explanation:

A correlation coefficient is a measure of how well the line of best fit fits the data.  The higher the correlation coefficient, up to 1.0 or -1.0, the better the fit. A positive correlation coefficient means an increasing data set, while a negative correlation coefficient means a decreasing data set.

We can see that this line of best fit is increasing, so our correlation coefficient will be positive.

However we can also see that the points are fairly scattered; this means this is not a very good fit.  This means that 0.19 is the better fit.

Complete the solution of the equation. Find the value of y when x equals -15. -x ‒ 8y = -1
valkas [14]
To complete the solution of - x - 8y = -1, we first need to substitute x for -15.
As so:

-(-15) - 8y = -1
15 - 8y = -1

Next, we can subtract 15 from each side to get:

15 - 15 - 8y = -1 - 15
- 8y = -16

Now, we can divide by -8 on each side to get the y by itself:

-8y / -8 = -16 / -8 
y = -16 / -8
y = 2

There we go! <em>y</em> = 2 when x = -15! Hope I could help you out! Have a good one.

Consider the graph of function g below. A diagonal curve declines from (negative 1, 9) through (0, 6), (2, 0), (3, negative 3),
KatRina [158]

The parent function, f(x) = x, might undergo the following series of transformations to produce the graph: Reflect over the y-axis, vertical stretch by a factor of 2, and then shift up 6 units.

<h3>What is geometric transformation?</h3>

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

The converted function, when compared to the original function, will be obtained as y = -2x + 6 if we plot it on the coordinate plane.

The only method by which the provided graph may be converted to the coordinates specified in the problem is;

Reflect over the y-axis, multiply the vertical stretch by two, and then move up six units.

Thus, the parent function, f(x) = x, might undergo the following series of transformations to produce the graph: Reflect over the y-axis, vertical stretch by a factor of 2, and then shift up 6 units.
