Transform the equation to isolate x: ax = bx + 1. How is the value of x related to the difference of a and b?
(please help me)
Answer:
x = 1/a-b.
x is the reciprocal of the difference of a and b.
x is 1 over the difference of a and b.
x is the quotient of 1 and the difference of a and b.
Step-by-step explanation:
i did it
The transformation of the given equation ax = bx + 1 for the x will be 1/(a - b).
What is the substitution of an equation?In the by substitution method, one of the equations is calculated for one of the variables, which is then transferred back into the other equation where the chosen variable is a replacement, and the second equation is then calculated for. The first variable is then home safely.
In other words, substitution is a method to find the value of variables x and y by just substituting x and y to another equation.
The substitution method is more good than the elimination method.
Given that the equation
ax = bx + 1
Transfer bx to the left side
ax- bx = 1
Take common x from the left-hand side
x(a - b) = 1
Divide a - b on both sides
x = 1/(a - b) hence it will be the correct transformation.

For a given input value xxx, the function ggg outputs a value yyy to satisfy the following equation. -4x-6=-5y+2−4x−6=−5y+2minus, 4, x, minus, 6, equals, minus, 5, y, plus, 2 Write a formula for g(x)g(x)g, left parenthesis, x, right parenthesis in terms of xxx. g(x)=g(x)=g, left parenthesis, x, right parenthesis, equals
Answer:
The function g(x) that outputs a y value to satisfy the equation -4·x - 6 = -5·y + 2 is g(x) = y = 4/5·x + 8/5
Step-by-step explanation:
The y value of the equation that the required function g(x) outputs = -4·x - 6 = -5·y + 2
Therefore, we have;
-4·x - 6 = -5·y + 2
-5·y + 2 = -4·x - 6
-5·y = -4·x - 6 - 2 = -4·x - 8
Therefore, y = (-4·x - 8)/(-5) = 4/5·x + 8/5
y = 4/5·x + 8/5
Which gives;
g(x) = y = 4/5·x + 8/5
Therefore;
The function g(x) that outputs a y value to satisfy the equation -4·x - 6 = -5·y + 2 is g(x) = y = 4/5·x + 8/5
There are 47 tables of 4 and 16 tables of 5 how many customers are in the restaurant
Answer:
268
Step-by-step explanation:
We need to multiply and add:
47 tables of 4 means there are a total of 47 * 4 = 188 people at these tables.
16 tables of 5 means there are a total of 16 * 5 = 80 people at these tables.
Add them up to get: 188 + 80 = 268 customers total.
A quadrilateral has vertices A, B, C, and D. A line of reflection is drawn so that A is 6 units away from the line, B is 4 units away from the line, C is 7 units away from the line, and D is 9 units away from the line. When quadrilateral ABCD is reflected about the line of reflection to create a new quadrilateral A'B'C'D', which resulting point is closest to the line of reflection? (1 point) O A' O B O D' OC
Answer:
The correct option is O B'
Step-by-step explanation:
We have a quadrilateral with vertices A, B, C and D. A line of reflection is drawn so that A is 6 units away from the line, B is 4 units away from the line, C is 7 units away from the line and D is 9 units away from the line.
Now we perform the reflection and we obtain a new quadrilateral A'B'C'D'.
In order to apply the reflection to the original quadrilateral ABCD, we perform the reflection to all of its points, particularly to its vertices.
Wherever we have a point X and a line of reflection L and we perform the reflection, the new point X' will keep its original distance from the line of reflection (this is an important concept in order to understand the exercise).
I will attach a drawing with an example.
Finally, we only have to look at the vertices and its original distances to answer the question.
The vertice that is closest to the line of reflection is B (the distance is 4 units). We answer O B'

His parcel is a cuboid with dimensions 10 cm, 20cm and 40 cm. 20 cm 10 cm 40 cm to scale He looks at the prices of two companies, WeDeliver and GoParcels. Not drawn WeDeliver Total cost: Sum, in cm, of the 3 dimensions * £0.80 Find the cost of sending the parcel with each company. Give each of your answers
Answer:
For WeDeliver= $224
For GoParcels = $56
Step-by-step explanation:
Since we are told his parcel is a cuboid with dimensions 10cm, 20cm, and 40 cm, it means the parcel consists of 4 edges of 10 cm, 4 edges of 20 cm, and 4 edges of 40 cm.
For WeDeliver, the Total Cost is:
Sum, in cm, of the dimensions x 0.80, which is, (10cm *4) + (20cm *4) + (40cm *4) = 280cm x 0.80 = $224. While
For GoParcels, the Total Cost is:
Total area, in [tex]cm^{2}[/tex], of all 6 faces, x .02
Remember that a cuboid has six (6) faces or sides, so the total area would be gotten by taking note of the length of each visible side of the parcel and then multiplying to get the other side after which we sum after doing so we get:
[tex]800^{cm2}[/tex] for front side[tex]800^{cm2}[/tex] for the backside[tex]400^{cm2}[/tex] for the top[tex]400^{cm2}[/tex] for the bottom[tex]200^{cm2}[/tex] for the left side[tex]200^{cm2}[/tex] for the right side.Total area = [tex]2,800^{cm2}[/tex] * 0.02 = $56

Graph the image of this figure after a dilation with a scale factor of 2 centered at the origin.
Answer:
The graph of the image is attached below.
Step-by-step explanation:
Let the points of the figure
A(1, -1)B(3, -1)C(1, 2)D(3, 2)We need to find the image coordinates after the dilation by a scale factor of 2 centered at the origin.
The rule of dilation by a scale factor of 2 is:
Dilation with scale factor 2, multiply by 2.
(x, y) → (2x,2y)
The coordinates of the vertices of the image according to this rule will be:
(x, y) → (2x,2y)
A(1, -1) → (2(1),2(-1)) = A'(2, -2)
B(3, -1) → (2(3),2(-1)) = B'(6, -2)
C(1, 2) → (2(1),2(2)) = C'(2, 4)
D(3, 2) → (2(3),2(2)) = D'(6, 4)
Therefore, the coordinates of the vertices of the image will be:
A'(2, -2)B'(6, -2)C'(2, 4)D'(6, 4)The graph of the image is attached below.
