i hope this helps
so look...
m=miles
(5m+6=m)<------ answer
hope this helps
Answer:
how can someone solve dis?
Step-by-step explanation:
Answer:
Great work!
Step-by-step explanation:
These kind of questions are calculated through Riemann Sum. You can evaluate any definite integral using the Riemann Sum. It should be in the following form:
f(x)dx on the interval [a, b], or
Now f(x) is simply y. Therefore in this example y = x^3 - 6x. We just need the sufficient amount of data to apply the Riemann Sum, including the interval [a, b] that bounds the area, and the the number of rectangles 'n' that we need to use.

Answer:
Hence, the system of equations that is used to represent the situation is:
23x+7y=94-----(1)
16x+14y=38------(2)
Step-by-step explanation:
Let x represent the amount of points received for a correct answer and y represent the amount of points for an incorrect answer.
- You’ve gotten 23 questions correct and only 7 wrong,giving you a total score of 94 points.
So, the equation formed is:
23x+7y=94
- Your friend, on the other hand, got 16 questions correct and 14 wrong for a total score of 38 points.
So, the equation formed is:
16x+14y=38
Hence, the system of equations that is used to represent the situation is:
23x+7y=94-----(1)
16x+14y=38------(2)
The foundational concept of algebra is to use the alphabetical letters to find the unknown number.
Algebra is the concept that uses the alphabetical letters such as x, y, z, etc. to calculate the unknow numbers. here the letters are also called as variables. The values that are known in the expression as termed as constants.
The general operations performed on the algebra is
- Addition = x + y
- Subtraction = x - y
- Multiplication = x * y
- Division = x / y
Here the alphabets x and y are called variables.
Order of operations:
The order of operation in algebra is given as follows
- Perform all the operations inside the brackets
- Perform the operations on roots and exponents
- Perform all the division and multiplication operations moving from left to right
- Perform all the addition and subtraction operations from left to right.
