The solution of the given linear equation in one variable t - 2(3 - 2t) = 2t + 9 is at t = 5.

According to the given question.

We have a linear equation in one variable.

t -2(3-2t) = 2t + 9

As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Thereofre, the solution of the linear equation in one variable  t -2(3-2t) = 2t + 9 is given by

t - 2(3 - 2t) = 2t + 9

⇒ t - 6 + 4t = 2t + 9          (by distributive rule)

⇒ 5t - 6 = 2t + 9

⇒ 5t - 2t = 9 + 6

⇒ 3t = 15

⇒ t = 15/3

⇒ t = 5

Hece, the solution of the given linear equation in one variable t - 2(3 - 2t) = 2t + 9 is at t = 5.

The equation y = -3x - 19 (slope-intercept form) in Ax + By = C form is 3x + y = 19.

The slope-intercept form of a linear equation is a way to express a linear equation in the form y = mx + b, where y represents the dependent variable, x represents the independent variable, m represents the slope of the line, and b represents the y-intercept.

According to the given information:

The given equation, y = -3x - 19, is already in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. However, to write it in the Ax + By = C form, also known as the standard form of a linear equation, we need to rearrange it.

The standard form of a linear equation is Ax + By = C, where A, B, and C are constants, and A is usually required to be a positive integer or zero.

To convert y = -3x - 19 into standard form, we can follow these steps:

Step 1: Move all the terms to one side of the equation.

y + 3x = -19

Step 2: Multiply all the terms by -1 to make the coefficient of x positive.

-1(y + 3x) = -1(-19)

-y - 3x = 19

Step 3: Rewrite the equation with positive coefficients for x and y.

3x + y = 19

So, the equation y = -3x - 19 in Ax + By = C form is 3x + y = 19.

an=a1+d(n−1)  is the explicit and a recursive formula for each sequence .

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.

Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.

An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.

The total time taken by the ant to take cookie crumb from the kitchen table to an anthill is 83.33 minutes.

What is the linear system?

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

An ant carries food at a speed of 1 cm/s.

The kitchen table to an anthill, a distance of 50 m.

We know the relation between speed and time.

Time=distance/speed.

Speed = 1 cm per second = 0.6 m per minute

Distance = 50 m

Then total time taken will be

=50/0.6

=83.33

Thus, the total time taken by the ant to take cookie crumb from the kitchen table to an anthill is 83.33 minutes.

Answer:

1/8

Step-by-step explanation:

==================================================

Work Shown:

m = slope

m = (y2 - y1)/(x2 - x1)

m = (5 - 3)/(j - 8)

m = 2/(j - 8)

Plug in the given slope of -1/4 and solve for j

m = 2/(j - 8)

-1/4 = 2/(j - 8)

-1*(j-8) = 4*2

-j + 8 = 8

-j = 8-8

-j = 0

j = 0

The slope through (8,3) and (0,5) is -1/4

--------------

Check:

m = (y2 - y1)/(x2 - x1)

m = (5-3)/(0-8)

m = 2/(-8)

m = -1/4

The answer is confirmed.

Answer:

j = 0

Step-by-step explanation:

Slope-intercept form of a linear equation:

[tex]\large\boxed{y=mx+b}[/tex]

where:

Given:

Substitute the given slope and point into the formula and solve for b:

[tex]\begin{aligned}y & = mx+b\\\implies 3 & = -\dfrac{1}{4}(8)+b\\3 & = -2+b\\3+2&=-2+b+2\\5&=b\\\implies b & =5\end{aligned}[/tex]

Substitute the given slope and found value of b into the formula to create an equation for the line:

[tex]\boxed{y=-\dfrac{1}{4}x+5}[/tex]

Substitute the point (j, 5) into the equation and solve for j:

[tex]\begin{aligned}y&=-\dfrac{1}{4}x+5\\\implies 5&=-\dfrac{1}{4}j+5\\5-5&=-\dfrac{1}{4}j+5-5\\0&=-\dfrac{1}{4}j\\\implies j&=0\end{aligned}[/tex]

When an angle exists encircled by a circle, its measure exists equivalent to the intercepted arc's measure divided by two.

The measure of m WX is 66.

The arc that is inside the inscribed angle and whose endpoints are on the angle is known as the intercepted arc. Anywhere on the circle that the sides of an inscribed angle intersect to produce an intercepted arc can serve as the angle's vertex.

Angles with vertices on a circle and that cross an arc on the circle are said to be inscribed angles. Half of the intercepted arc's length and half of the central angle's length intersecting that same arc make up the measure of an inscribed angle. Congruent inscribed angles are those that intersect the same arc.

According to the Inscribed Angle Theorem, an inscribed angle's measure is equal to half of its intercepted arc's measure. Congruent inscribed angles are those that intersect the same arc.

In the given diagram, XY is a semi-circle. So,

m XWY = 180

m WX + m WY = 180

If an angle is inscribed in a circle, then the measure of the angle equals  one half the measure of its intercepted arc. 

m WY = 2(m ∠X)

m WY = 2(m ∠X) = 114

Therefore, m WX = 180 - m WY = 66.

According to the question, for the average sale price the given parameters are mean as $4200 and standard deviation as $250.

As per normal distribution, the standard formula is as written below:

[tex]z = \frac{value - mean}{SD}[/tex]

And through normal distribution, the value of z = -0.52 which gives the area of the left bounded.

Now, substitute the values in the given expression, we get:

[tex]-0.52=\frac{x-4200}{250}[/tex]

Now the calculated value of 'x' = $4070.

To calculate the 30 percent of the mountain bike, the sale price will be $4068.90.

Therefore, the 30th percentile of the distribution is $4068.90.

If a machine operator can program machine #1 to produce 100 parts per hour, but the machine requires 2 hours of service each day when it is not operating and machine #2 can produce only 80 parts per hour, but only requires 30 minutes of service each day, then both the machines are equal in productivity in an eight hour work day.

To determine which machine is more productive in an eight hour work day, an algebraic expression can be used.

x = y ( 8 hours - s )

Here, x = to the parts produced in an eight hour work day

y = parts produced per hour

s = service hours

Thus, the parts produced by both the machines in an eight hours work day can be calculated using this algebraic expression as follows,

For Machine #1:

y = 100 and s = 2

x = 100 ( 6 )

x = 600

Machine #2:

y = 80 and s = 0.5

x = 80 ( 8 - 0.5 )

x = 80 ( 7.5 )

x = 600

Hence, both machines are equally productive in an eight hour work day.

The equation of the line, with slope equal to 5 and passing through the point located at (0 , 2), is 5x - y = -2.

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 and (x1 , y1) = (0 , 2)

(y - 2) = 5(x - 0)

y - 2 = 5x

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

y - 2 = 5x

y = 5x + 2

In standard form, the equation of the line is:

y = 5x + 2

5x - y = -2
