There are two ways to represent this equation: "x + (x + 1) + (x + 2) = 42" and "(x minus 1) + x + (x + 1) = 42".
What is equation?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. A mathematical phrase with two equal sides and an equal sign is called an equation. An example of an equation is 4 + 6 = 10.

( 2 , 5 ) and ( 0 , 0 )
Which ordered pairs are solutions of the inequality?Here we have the linear inequality:
2x - 3y < 15
To check which ordered pairs are solutions, we just need to evaluate these points on the inequality and see if it becomes true or not.
For example, with the first pair (2, 5) we will get:
2*2 - 3*5 < 15
4 - 15 < 15
-11 < 15
This is true, so (2, 5) is a solution.

What is the equation of the line that passes through the point (-1,-5) and has a slope of 1?
Answers
Answer:
y=x-4
Step-by-step explanation:
if the slope is 1, the y intercept is -4
What is the equation of the line that passes through the point (-1,-5) and has a slope of 1?
The equation of a line in slope-intercept form is given by y = mx + b, where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.
Since the line passes through the point (-1,-5) and has a slope of 1, we can substitute these values into the equation to solve for the y-intercept. We get:
y = 1x + b
(-5) = 1(-1) + b
-5 = -1 + b
-4 = b
Therefore, the equation of the line that passes through the point (-1,-5) and has a slope of 1 is y = 1x - 4.

The factored form of f(x) is f(x) = (x+2) (x+2)(x+4)
What is a factor?
A factor is a number/expression that divides another number/expression, leaves zero remainder . In other words, if multiplying two numbers/expressions gives us a product, then the numbers/expressions we are multiplying are factors of the product because they are divisible by the product.
f(x) = x³ +8x² + 20x + 16
The value of x at which f(x) is zero, is the root
x= -2 is a root
so, ( x- (-2) ) = ( x+2) is a factor
Divide the polynomial x³ +8x² + 20x + 16 by ( x+2) using long division method:
x+2) x³ +8x² + 20x + 16 ( x² + 6x + 8
x³ + 2x²
_______________________
6x² + 20x + 16

f(x)= (x+2) (x² + 6x + 8 )

Answers
Answer:
Yes, the triangles are similar, because all angles are congruent and the sides are proportional.
Step-by-step explanation:
In similar triangles the corresponding angles have the same measurement. The sum of the interior angles of a triangle is 180. Both triangles have a 90 angle. 180-90 = 90. The other two answer must add to 90.
90 - 51 = 39. So each triangle has a 90, 51 and 39 degree angle.
The sides are also proportional. The scale factor from the smaller triangle to the larger is 2 and if you go the other way the scale factor is 1/2

Bart is writing lines on a chalkboard that is initially empty. It ordinarily takes Bart 50 minutes to cover the whole board; however, today, Nelson is erasing the board while Bart is writing. Nelson can erase the board in 80 minutes by himself. If they work simultaneously, how long will it be until the whole board is covered?
Answers
think about this conceptually first. The difference between their rates of work is going to be the total speed at which the chalk board fills up (speed of writing - speed of erasing).
Ok, so we need to find the speed that Bart is writing, and the speed at which Nelson is erasing.
Bart: 50 minutes/ 1 board
However, we want to find his speed, which will be in boards/minute. Flip the fraction to get 1 board/50 minutes. Then multiply top and bottom by 1/50 in order to get 1/50 board per minute.
Bart's Speed = 1/50 board per minute
Do the same for Nelson, to get 1/80 board per minute (erasing).
The difference between these will be 1/50 - 1/80 = 3/400 board per minute
Since we want to know how long it will take to fill the board at this rate, we multiply 1 board * 1/(3/400) minute per board - this is the same as 1 * 400/3
So, the answer is 400/3 minutes, or 133.33 minutes, or 2 hours, 13 minutes.
