The solution for x in the equation ax = bx + c is x = c/(a - b)
How to determine the solution for x in the equationFrom the question, we have the following parameters that can be used in our computation:
ax=bx+c
Also, from the question, we have the following variable to solve
Variable = x
Rewrite the given equation as
ax = bx + c
Using the above as a guide, we have the following:
Subtract bx from both sides of the equation
So, we have the following representation
-bx + ax = bx + c - bx
Evaluate the like terms
ax - bx = c
So, we have
x(a - b) = c
Divide by a - b
x = c/(a - b)
Hence, the solution is x = c/(a - b)

A V shape with vertex at negative 1 point 5 comma zero and passing through the points negative 2 comma 1 and negative 1 comma 1.
A. f(x) = |x| + 1.5
B. f(x) = |x| − 1.5
C. f(x) = |x − 1.5|
D. f(x) = |x + 1.5|
The absolute value function that is represented in the graph is f(x) = |x + 1.5| So the correct option is D.
What absolute value function is represented by the graph?The general absolute value function is:f(x) = |x|This absolute value function has a vertex at the point (0, 0). We know that the graphed function has a vertex at the point (-1.5, 0).
So basically we had a horizontal translation of -1.5 units or 1.5 units to the left. That is written as: g(x) = f(x + 1.5)
Replacing the absolute value function we get:g(x) = |x + 1.5|

a line with a slope of -3 passes through the point -3,8 what is its equation in slope intercept form
TIME SENSITIVE
(2,6)
x-y=4
(a) write an equation of the line that passes through the point and is parallel to the given line
(b) write an equation of the line that passes through the point and is perpendicular to the given line
Answer:
(a) Equation of parallel line is y = x + 4
(b) Equation of perpendicular line is y = - x + 8
Step-by-step explanation:
Given line is
x - y = 4
Rewrite this as
x - 4 = y
or
y = x - 4
This is the equation of a line in slope intercept form which is generally
y = mx + b
where m is the slope and b the y-intercept
Here m = 1, b = -4
(a) A parallel line will have the same slope but a different y-intercept
So for starters we can write the equation of the parallel line as
y = x + b
Since this passes through (2,6) sub 2 for x and 6 for y to get
6 = 2 + b
==> b = 4
Equation of the line is
y = x + 4
(b) A perpendicular line will have as slope -1/m where m is the slope of the original line
Here m = 1, so -1/m = -1/1 = -1
Equation will be of the form
y = -x + b
Since this also passes through (2,6)
6 = -2 + b
==> b = 6 + 2 = 8
Equation of perpendicular line is
y = -x + 8

y = -2/5 x -11/5 is the equation of line with slope -2/5 that passes through the point (2, -3).
What is the equation of line?The slope of the line is the rise to run ratio, or the rise divided by the run. It expresses the slope of a line in the coordinate plane.
The standard form of an equation is y = mx+c.
Here given,
A line with a slope of -2/5 that passes through the point (2, -3).
Simplify y = mx+c with m=2/5 and (x, y)=(2, -3). That is to say,
-3 = -2/5 (2)+c
⇒ -3 = -4/5 +c
⇒ c = -3 + 4/5
⇒ c = (-15 + 4) / 5
=> c = -11/5
When m = -2/5 and c = -11 /5 are substituted in y = mx+c, we get
y = -2/5 x -11/5
As a result, an equation for a line with a slope of -2/5 that passes through the point (2,-3) is y = -2/5 x -11/5.

An independent group of food service personnel conducted a survey on tipping practices in a large metropolitan area. They collected information on the percentage of the bill left as a tip for 20 randomly selected bills. The average tip was 11.1% of the bill with a standard deviation of 2.8%. Assume that the tips are approximately normally distributed. Construct an interval to estimate the true average tip (as a percent of the bill) with 90% confidence. Round the endpoints to two decimal places, if necessary.
Assuming that the tips are approximately normally distributed, an interval to estimate the true average tip (as a percent of the bill) with 90% confidence is (10.47, 11.73).
How to construct the confidence interval?Assuming that the tips are approximately normally distributed, we would determine both the lower limit and upper limit for the confidence interval where 90% of the sample means occur as follows;
Lower limit = μ - σ/√x
Lower limit = 11.1 - 2.8/√20
Lower limit = 11.1 - 0.63
Lower limit = 10.47
For the upper limit, we have:
Upper limit = μ - σ/√x
Upper limit = 11.1 + 2.8/√20
Upper limit = 11.1 + 0.63
Upper limit = 11.73

if three sides of a triangle are in ratio of 3:5:7 and the perimeter of the triangle is 12xm. what is the length of the longest side?
The required length of the longest side will be 28/5 cm in the triangle.
What is the perimeter of a triangle?The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.
We have been given that the three sides of a triangle are in the ratio of 3:5:7
Let's assume the sides are 3x, 5x, 7x
Since the perimeter of the triangle is 12 cm.
So, 3x+5x+7x = 12
Apply the addition operation,
15x = 12
x = 12/15
Reduce the above fraction to the simplest form
x = 4/5
So, longest side = 7x = 28/5 cm
Thus, the required length of the longest side will be 28/5 cm in the triangle.

,( ______0) and (______,______)
The coordinates of the other vertices of the triangle are (2a, 0), (2a, b), and (a, b).
What are the coordinates of the vertices of the triangle?
The coordinates of the vertices of a triangle are (x1,y1), (x2,y2), and (x3,y3). The line joining the first two is divided in the ratio l:k and the line joining this point of division to the opposite angular point is then divided in the ratio m:k+l.
To find the coordinates of the other vertices of the triangle, you can use the fact that the midpoint of a line segment is located at the average of the coordinates of the endpoints of the segment.
If the midpoint of one side of the triangle is located at (a, 0), then the coordinates of the two endpoints of this side must be (a, 0) and (2a, 0). The coordinates of one of the vertices is (2a, 0), and since this vertex is not the one located at the origin, the coordinates of the other vertex must be the origin, or (0, 0).
If the midpoint of another side of the triangle is located at (2a, b), then the coordinates of the two endpoints of this side must be (2a, b) and (2a, 0). One of the endpoints is (2a, 0), which we already know is a vertex of the triangle. The other endpoint, (2a, b), is also a vertex of the triangle.
Finally, if the midpoint of the third side of the triangle is located at (a, b), then the coordinates of the two endpoints of this side must be (a, b) and (0, 0). One of the endpoints is (0, 0), which we already know is a vertex of the triangle. The other endpoint, (a, b), is also a vertex of the triangle.
Hence, the coordinates of the other vertices of the triangle are (2a, 0), (2a, b), and (a, b).

Terri is sawing wood into shorter pieces of equal lengths. Some original pieces are 30 inches long, some are 48 inches long, and some are 72 inches. She cannot waste any wood. What is the longest possible length of the shorter pieces that Terri saws?
Answer:
24 inches
Step-by-step explanation:
To find the longest possible length of the shorter pieces that Terri can saw, you need to find the greatest common factor (GCF) of the three original lengths: 30 inches, 48 inches, and 72 inches.
The GCF of 30, 48, and 72 can be found by finding the prime factorization of each number and taking the lowest exponent for each prime factor.
30 = 2 * 3 * 5
48 = 2^4 * 3
72 = 2^3 * 3^2
The GCF is 2^3 * 3 * 5, or 24 inches. Therefore, the longest possible length of the shorter pieces that Terri can saw is 24 inches.
Hello,
I hope you and your family are doing well!
To find the GCF is to use the Euclidean algorithm, which involves repeatedly dividing the larger of the two numbers by the smaller one until the remainder is 0. This can be a quicker method for finding the GCF of larger numbers.
For example:
72 / 30 = 2 with a remainder of 12
30 / 12 = 2 with a remainder of 6
12 / 6 = 2 with a remainder of 0
The last non-zero remainder is 6, so the GCF is 6.
Regardless of the method used, the GCF of 30, 48, and 72 is 6, so the longest possible length of the shorter pieces that Terri can saw is 6 inches.
