Answer:

-72x + 10y

Step-by-step explanation:

First apply the Distributive Property of Multiplication:

-8(6x - 7y) becomes -48x + 7y and -(24x - 3y) becomes -24x + 3y.

Combining like terms, we get -72x + 10y

Answer:

-21x+53y

In the least-squares regression line, the desired sum of the errors (residuals) should be: zero

A number system is defined as a system of writing to express numbers.

The key word here is "desired". We wish to make the errors as small as possible. The smallest any individual error can get is 0. Adding the entire collection of zeros will sum in a total of zero.

An error of zero means we hit the mark exactly. The unfortunate reality is that error is going to happen, so we'll have some positive error values with any regression line (or curve). It's only when all points are on the same line is when we have zero error and perfect interpolation rather than regression.

Again, the question is asking about desired error and the ultimate goal is to make the error zero. The next best thing is to minimize it as small as possible

Hence in the least-squares regression line, the desired sum of the errors (residuals) should be: zero

-2

Step-by-step explanation:

16=-4x+4+4

16=-4x+8

4x=8-16

4x=-8

x=-2

Tthe required value of x is -2 for which the given expression is true.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Given expression,
16 = -4(x - 1) + 4
16 - 4 = -4(x - 1)
x - 1 = 12 / -4
x = -3 + 1
x = -2

Thus, the required value of x is -2 for which the given expression is true.

Step-by-step explanation:

Saving the long, drawn out derivation of the formulas to find the x and y coordinates of the directed point, suffice it to say that it is:

x coordinate: [tex]\frac{bx_1+ax_2}{a+b}[/tex] and

y coordinate: [tex]\frac{by_1+ay_2}{a+b}[/tex]

where x1, x2, y1, and y2 are the coordinates from the given points and a and b are the numbers in the ratio, namely a = 3 and b = 4. Filling in accordingly:

the x coordinate of the directed point is

[tex]\frac{4(-9)+3(-2)}{7}[/tex] which simplifies down to -6, and

the y coordinate of the directed point is

[tex]\frac{4(-7)+3(7)}{7}[/tex] which simplifies down to -1.

The coordinate of the point is (-6, -1). Write that down so you don't forget it.

The coordinates of the point that partitions the line segment from (-9,-7) to (-2,7) into a ratio of 3 to 4 are (-5, 1).

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

To find the point that partitions the line segment from (-9,-7) to (-2,7) into a ratio of 3 to 4, we need to use the formula.

[tex]P = ( (4x_2 + 3x_1)/(4+3), (4y_2 + 3y_1)/(4 + 3) )[/tex]

where P is the point we're looking for, (x1, y1) and (x2, y2) are the coordinates of the two endpoints of the segment, and the numbers 4 and 3 come from the ratio 3 to 4.

Plugging in the values.

P = ( (4 x (-2) + 3 x (-9))/(4 + 3), (47 + 3(-7))/(4 + 3) )

Simplifying.

P = (-5, 1)

Therefore,

The coordinates of the point that partitions the line segment from (-9,-7) to (-2,7) into a ratio of 3 to 4 are (-5, 1).

Answer:

We conclude that for 1/2 batch, Faird would require 3/8 cups of sugar.

Step-by-step explanation:

We need to determine the expression for the amount of sugar Freed needs to make 1/2 batch.

Let 'x' be the batch and 'y' be the amount of sugar

Suger needed for a full batch = 3/4 cup of a sugar

so

But, Farid is making 1/2 of the batch.

Thus, multiply both sides by 1/2

[tex]x\times \frac{1}{2}\:=\:\frac{3}{4}y\times \frac{1}{2}[/tex]

[tex]\frac{x}{2}=\frac{3y}{8}[/tex]

Therefore, we conclude that for 1/2 batch, Faird would require 3/8 cups of sugar.
