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

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. machine #2 can produce only 80 parts per hour, but only requires 30 minutes of service each day. which machine is more productive in an eight hour work day?
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.

What is the y -coordinate of the y -intercept of the line?
The y-intercept of the equation of a line in general form is:(0, -c/b) or -c/b
The y-intercept is the point where the graph intersects the y-axis. To graph, any function that is of the form y = f(x) finding the intercepts is really important. There are two types of intercepts that a function can have. They are the x-intercept and the y-intercept. An intercept of a function is a point where the graph of the function cuts the axis.
The y-intercept of a function is a point where its graph would meet the y-axis. The x-coordinate of any point on the y-axis is 0 and we use this fact to derive the formula to find the y-intercept. i.e., the y-intercept of a function is of the form (0, y).
The equation of a straight line in general form is ax+by+c=0. For the y-intercept, we substitute x=0 and solve it for y.
a(0)+ by + c =0
by + c =0
y = - c/b
Thus, the y-intercept of the equation of a line in general form is:(0, -c/b) or -c/b

Determine whether each sequence is arithmetic, geometric, or neither. Then find the tenth term. -12,-5,2,9,16, . . . .
The sequence -12,-5,2,9,16, . . . .. is an arithmetic sequence and its 10th term is a(10) = 65
To determine whether a sequence is an arithmetic or geometric one, we need to check the relation between two consecutive terms.
In an arithmetic sequence, the nth term is obtained by adding the (n-1)th term with a constant, called a common difference (d).The given sequence is:
-12,-5,2,9,16, . . . .
In this sequence:
a(1) = -12
a(2) = -5
a(3) = 2
a(4) = 9
and so on.
Notice that:
a(2) - a(1) = -5 - (-12) = 7
a(3) - a(2) = 2 - (-5) = 7
a(4) - a(3) = 9 - 2 = 7
Since each consecutive terms have common difference, then, the given sequence is an arithmetic sequence. Furthermore, the common difference, d = 7.
The formula for the nth term in an arithmetic sequence is given by:
a(n) = a(1) + (n - 1) . d
Substitute n = 10, d = 7, and a(1) = -12
a(10) = -12 + (12 - 1) . 7
a(10) = -12 + 77 = 65

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.
What is meant by inscribed arc?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.

The points (8, 3) and (j, 5) fall on a line with a slope of -1/4. What is the value of j? help me ASAP
==================================================
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:
m is the slope.b is the y-intercept.Given:
Slope = -¹/₄Point = (8, 3)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]
Solution
Therefore, the value of j is 0.
Write an equation of each line.slope =5 ; through (0,2)
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

The interior angle measure of a regular polygon is given. Identify the polygon.
108
The regular polygon with an interior angle of measure 108° is a pentagon.
A regular polygon is a polygon that has equal side lengths and equal interior angle measures.
Interior angle of a polygon is the angle inside it that is formed by two adjacent sides. The number of interior angles formed inside a polygon is the same as the number of its sides. Meanwhile, the sum of all the interior angles of any polygon is constant to that polygon and depends on the number of sides.
sum = 180(n - 2)
Using this formula,
sum = 180(n - 2)
where n = number of sides of the polygon = number of interior angles
sum = measure of interior angle x n
108n = 180(n - 2)
108n = 180n - 360
180n - 108n = 360
72n = 360
n = 5
If the polygon has 5 sides and 5 interior angles, then the regular polygon is a pentagon.
