Final answer:
To solve the equation ax - y = bx for x, add y to both sides, combine x terms, factor x out, and divide by (a - b) resulting in the solution x = y / (a - b).
Explanation:
To solve the given equation ax - y = bx for x, we aim to isolate x on one side of the equation:
First, we add y to both sides of the equation: ax = bx + y.
Next, we group the x terms together: ax - bx = y.
Then, we factor out x: x(a - b) = y.
Finally, we divide both sides by (a - b) to solve for x: x = y / (a - b).
So, the solution is x = y / (a - b).

graph of two infinite lines that intersect at a point. One line is solid and goes through the points negative 3, 0, negative 4, negative 1 and is shaded in below the line. The other line is solid, and goes through the points 1, 1, 2, negative 1 and is shaded in below the line.
Answer:
The system of inequalities is
[tex]y\leq x+3[/tex] and [tex]y\leq -2x+3[/tex]
The solution is the shaded green area
Step-by-step explanation:
step 1
Find the equation of the inequality A
The line is solid and goes through the points negative 3, 0, negative 4, negative 1 and is shaded in below the line
Find the slope
(-3,0),(-4,-1)
m=(-1-0)/(-4+3)=1
The equation of the line is y=mx+b
we have
m=1
b=3 ----> the y-intercept (see the graph)
substitute
y=x+3 -----> equation of the solid line A
The equation of the inequality is
[tex]y\leq x+3[/tex] -----> inequality A
step 2
Find the equation of the inequality B
The line is solid and goes through the points 1, 1, 2, negative 1 and is shaded in below the line
Find the slope
(1,1),(2,-1)
m=(-1-1)/(2-1)=-2
The equation of the line is y=mx+b
we have
m=-2
b=3 ----> the y-intercept (see the graph)
substitute
y=-2x+3 -----> equation of the solid line B
The equation of the inequality is
[tex]y\leq -2x+3[/tex] -----> inequality B
therefore
The system of inequalities is
[tex]y\leq x+3[/tex] -----> inequality A
[tex]y\leq -2x+3[/tex] -----> inequality B
The solution is the shaded green area
The graph represents the system of inequalities y >= -x - 3 and y >= -3x + 4. This is concluded by observing the slopes, intercept points, and shading regions.
Explanation:The system of inequalities represented by the graph you provided can be deduced by the slopes, intercept points, and the regions of shading. Given the information, the solid line that goes through the points (-3, 0) and (-4, -1) can be represented by the equation y >= -x -3. Since the line is solid and the area below the line is shaded, the inequality symbol includes an equal sign which means the line itself is part of the solution.
For the second solid line that goes through the points (1, 1) and (2, -1), it can be represented by the equation y >= -3x + 4. Similarly, because the line is solid and the region below this line is shaded, the inequality symbol includes an equal sign.
Therefore, the system of inequalities that the graph represents is y >= -x - 3 and y >= -3x + 4.

the area of a rectangle is represented by x^2 - 5x - 14. what are the dimensions?
Answer:
Step-by-step explanation:
A = x² - 5x - 14
Factor using AC method. Here, a = 1, b = -5, and c = -14.
ac = 1×-14 = -14
Factors of -14 that add up to -5 are -7 and 2.
A = (x - 7)(x + 2)
So the dimensions are x-7 and x+2.
The dimensions of the rectangle represented by the quadratic equation x² - 5x - 14 could be 7 and -2, but in a physical context we only consider the positive value 7.
Explanation:The area of a rectangle is given by multiplying its length and width. In this case, the area is expressed as a quadratic equation, x² - 5x - 14 = 0. Quadratic equations typically represent parabolas when graphed on a two-dimensional plot, but in this case, we're looking for linear dimensions of a rectangle. To find the dimensions of the rectangle, we need to factor this equation.
The factors of this quadratic equation are (x - 7) and (x + 2). Therefore, the two dimensions of the rectangle could be 7 and -2. However, in real-world scenarios, dimensions are often positive values due to physical constraints (you can't have a rectangle with negative length or width). So, normally, we would only consider the dimension of 7 (from the factor x - 7) as the real solution to this problem.

What side length would be possible for a triangle if you already know the other two lengths are 19cm and 32cm
Please explain step by step
Answer:
13 < n < 51
Explanation:
Basically to find the lowest possible length, all you need to do is subtract the lower number from the higher number (32 - 19), and to find the greatest possible length, add the lower number and the higher number (32 + 19). Then you'd plug it in to this inequality: a < n < b, a being the difference, and b being the sum. But, if the triangle were a right triangle that would be a whole different story.

The symbol 5! means 5* 4*3*2*1. What is the greatest odd integer that is a factor of 5!?
Answer:
15
Step-by-step explanation:
5 ! = 120
Since 5 ! = 5 × 4 × 3 × 2 × 1, then
5 × 3 = 15 is the greatest odd factor of 5 !
The greatest odd integer that is a factor of 5 factorial (5!) is 5. This is because the definition of factorial involves multiplying a number by every number below it until reaching 1 and 5 is the largest odd number within this range.
Explanation:The greatest odd integer that is a factor of 5! (or 5 factorial) is 5. The factorial, represented by the symbol '!', is a function that multiplies a number by every number below it until it reaches 1. For example, 5! means 5 * 4 * 3 * 2 * 1. To find the greatest odd integer that is a factor of 5!, you simply need to identify the largest odd number that is a part of this multiplication, which is 5.
Let's clarify this with some simple math. Start from the number 5 itself, then move down: 5 (it's an odd number), 4 (it's even, exclude), 3 (it's odd, but less than 5), 2 (it's even, exclude), 1 (it's odd, but less than 5). Hence, the largest odd integer that is a divisor of 5! is 5.

One serving of pancakes takes one and two thirds cups of milk how many cups of milk will 36 servings of pancakes require?
To determine the amount of milk needed for 36 servings of pancakes, multiply one and two-thirds cups of milk by the number of servings. This results in a total of 60 cups of milk required.
Explanation:To find out how many cups of milk are needed for 36 servings of pancakes, when one serving requires one and two-thirds cups of milk, we use multiplication. We can make a conversion factor using our original recipe, likening it to a mathematical relationship or a stoichiometric relationship in chemistry. Here is the step-by-step calculation:
First, we convert one and two-thirds cups to an improper fraction: 1 2/3 = 5/3 cups.Next, we multiply the amount needed for one serving by the total number of servings: (5/3 cups) × 36 servings = 180/3 cups.Finally, we simplify the fraction 180/3 cups to get the total number of cups required: 180/3 = 60 cups.So, for 36 servings of pancakes, you would need 60 cups of milk.

An animal shelter spends $5.50 per day to care for each bird and $8.50 per day to care for each cat. Anna noticed that the shelter spent $291.50 caring for birds and cats on Thursday. Anna found a record showing that there were a total of 41 birds and cats on Thursday. How many birds were at the shelter on Thursday?
Answer:
19
Step-by-step explanation:
We can solve this problem using a system of equation in two unknowns.
Let b = number of birds.
Let c = number of cats.
The care of a bird costs $5.50, so for b number of birds, the cost of care is 5.5b.
The care of a cat costs $8.50, so for c number of cats, the cost of care is 8.5c.
The total cost of care for the birds and cats is 5.5b + 8.5c.
The total cost of care is $291.50. This must equal the expression we have above, so we get our first equation.
5.5b + 8.5c = 291.5
The total number of birds and cats is b + c, but we are told it is 41, so our second equation is:
b + c = 41
We now have the following system of two equations in two unknowns.
5.5b + 8.5c = 291.5
b + c = 41
Rewrite the first equation.
Multiply both sides of the second equation by -8.5, and write it under the first equation. Then add the equations.
5.5b + 8.5c = 291.5
+ -8.5b - 8.5c = -348.50
--------------------------------------
-3b = -57
Divide both sides of the equation by -3.
b = 19
Answer: there were 19 birds
By defining the number of birds and cats as variables and setting up a system of equations, we solved for the number of birds to be 19.
Let's define the number of birds as b and the number of cats as c. From the problem, we have the following equations:
b + c = 41 (total number of birds and cats)
5.50b + 8.50c = 291.50 (total cost of caring for birds and cats)
To solve for the number of birds, we follow these steps:
Step 1: Express the number of cats in terms of birds.
From the first equation, we get:
c = 41 - b
Step 2: Substitute this expression into the second equation.
5.50b + 8.50(41 - b) = 291.50
Expand and simplify the equation:
5.50b + 348.50 - 8.50b = 291.50
Combine like terms:
-3b + 348.50 = 291.50
Step 3: Solve for b.
Subtract 348.50 from both sides:
-3b = 291.50 - 348.50
-3b = -57
Divide both sides by -3:
b = 19
Therefore, there were 19 birds at the shelter on Thursday.

8 Females have to leave the room which then it would be 22 males and 22 females which is a 1-1 ratio
A ratio shows us the number of times a number contains another number. The number of females who should leave the conference room is 8.
What is a Ratio?A ratio shows us the number of times a number contains another number.
The ratio of females to males in the room is 15 to 11, therefore, the numbers of female to male ratio can be represented by 15x to 11x.
The sum of the total number of people in the room is 52, and can be represented as,
15x + 11x = 52
26x = 52
x = 2
Thus, the number of females in the conference room is 30(15x=15×2), while the number of males in the conference room is 22(11x=11×2).
Now, for the ratio to be 1:1, the number of males should be the same and the number of females should be equal to the number of males. Therefore, the number of females who should leave the conference room is,
Number of females who should leave conference room = Number of females before - Number of females after
Number of females who should leave conference room = 30 - 22 = 8
Hence, the number of females who should leave the conference room is 8.

What degree of rotation will cause the triangle below to map onto itself ?
Answer:
The triangle is rotated 360° ⇒ answer D
Step-by-step explanation:
* Lets revise some transformation
- If point (x , y) rotated about the origin by angle 90° anti-clock wise
∴ Its image is (-y , x)
- If point (x , y) rotated about the origin by angle 90° clock wise
∴ Its image is (y , -x)
- If point (x , y) rotated about the origin by angle 180°
∴ Its image is (-x , -y)
* There is no difference between rotating 180° clockwise or
anti-clockwise around the origin
- If point (x , y) rotated about the origin by angle 360°
∴ Its image is (x , y) the point itself
* There is no difference between rotating 360° clockwise or
anti-clockwise around the origin
* Now lets solve the problem
∵ The vertices of the triangle ABC are:
A is (-6 , 3) , B is (-5 , 7) , C is (-4 , 3)
∵ The triangle map onto itself
∴ A = A'
∴ B = B'
∴ C = C'
∴ The triangle is rotated 360° about the origin
D= 360
When you’re talking about rotation you go counterclockwise and each quadrant is another 90 degrees.
