What is the relationship between a and b

The equation of the line in point-slope form, with slope equal to 5/6 and passing through the point located at (22 , 12), is (y - 12) = 5/6(x - 22).

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).

Using the point slope form, plug in the values to set up the equation.

(y - y1) = m(x - x1)

where m = 5/6 and (x1 , y1) = (22 , 12)

(y - 12) = 5/6(x - 22)

In slope-intercept form, the equation of the line is:

(y - 12) = 5/6(x - 22)

y - 12 = 5/6 x - 110/6

y = 5/6 x - 19/3

In standard form, the equation of the line is:

y = 5/6 x - 19/3

5/6 x - y = 19/3

Multiplying both sides by 6,

5x - 6y = 38

Answer: x = 3/4

Step-by-step explanation:

The first step to solve this equation would be to simplify both sides of the equation by multiplying

1/4*12 - 1/4*8x = 2/3*6x

3 - 2x = 2x

3= 2x+2x

3=4x

x=3/4

Answer:

Step-by-step explanation:

AS THERE ARE 2 fractions 1/4 and 2/3, one way would be to first get rid of these by multiplying through by the LCM  12, giving:

12*1/4(12 – 8x) = 12*2/3(6x)

3(12 - 8x) = 8(6x)

The correct equation is:

|x - 32| = 0.78

In this case, x represents both the maximum and minimum accepted volumes.

We know that the mean volume is 32 fluid ounces, and the acceptable error is 0.78 fluid ounces.

Then the maximum acceptable volume is 32 + 0.78 fluid ounces, and the minimum acceptable volume is 32 - 0.78 fluid ounces.

This means that the absolute value of the difference between x, the volume, and 32, must be equal to 0.78

This is written as:

Answer:

1, 3 and 5

Step-by-step explanation:

You can formulate the postulate as:

x² + (x + 2)² + 15 = (x + 4)²

Which simplifies to x² - 4x + 3 = 0, with solutions x=1 and x=3

so 1, 3 and 5 must be the other tuple.

The equation of the line 3x + 2y = 6 is perpendicular with the equation of the line (A) 4x - 6y = 3.

Two lines are perpendicular with each other if they form right angle at the point of their intersection. The slopes of perpendicular lines are negative reciprocal of one another.

The slope, m, determines the steepness of a line. It can be measured by the vertical distance from one point to another divided by the horizontal distance of the same points.

In an equation in standard form, ax + by = c, the slope, m,  of the line is equal to a/b. On the other hand, in an equation in slope-intercept form, y = mx + b, m is the slope.

Determine the slope of the given line and each given choices:

3x + 2y = 6

m = a/b = 3/2

(A) 4x - 6y = 3

m = a/b = 4/-6 = -2/3

(B) y = -(3/2)x + 4

m = -3/2

(C) 2x + 3y = 12

m = a/b = 2/3

(D) y = (3/2)x + 1

m = 3/2

Since the slope of the given line is 3/2, taking its negative reciprocal, the slope of the perpendicular line should be -2/3. The line with the slope of -2/3 is (A) 4x - 6y = 3.

Hence, (A) 4x - 6y = 3 is perpendicular with 3x + 2y = 6.

FA recursive formula allows us to find each term in the geometric sequence using the previous term. Each new term is the product of the common ratio for that sequence and the previous term of that unknown or to-be-found term. If the common ratio is 9, each term is nine times the previous term.

The general term for the geometric sequence is,

A linear function is modeled by:

For Company A, we have two points on the column: (2, 33), (3, 49). Hence for one additional hour, the cost increased by $16, hence the slope is of 16 and:
