The simplified form of given expression is 
Answer: Option B
<u>Step-by-step explanation:</u>
Given expression:
To find the simplified form of the given expression
We know, x to the power 0 is equal to 1. i.e. 
. Therefore, it gets removed in the given expression.
As common ‘4’ in numerator and denominator also gets cancelled in the given expression
Bring negative exponents (in numerator) down (to denominator) to form positive exponents, we get the simplified form of given expression as below,
1. constructing a house
2. building a car
3. laying pipe our conduit, especially with bends
4. packing boxes on a truck
5. painting, gotta know area
6. filing a swimming pool, gotta know volume
Answer:
A. coefficients: 70, 12; variables: x, y.
B. 2 terms: 70x, 12y; separated by an addition symbol
C. 70x
Step-by-step explanation:
We will answer the questions in the context of this problem. In other problems, the meaning of "coefficient", "variable", and "term" may be different.
__
A. The coefficients are the numbers; the variables are the letters. Then the coefficients are 70 and 12; the variables are x and y.
__
B. Each product is a term. Terms are separated by the + sign. There are two terms in this expression, one on either side of the + sign. When an expression is written with no parentheses, the terms are separated by + or - signs. (Often, we think of the minus sign as being part of the coefficient of the term. Then we can say terms are separated by + signs. 10x + (-32y), for example.)
__
C. When you match the coefficients to the numbers in the problem statement, you see that the number matching the earnings at the diner is <em>$70 per shift</em>. If we assume that x represents the number of shifts worked at the diner, then the term 70x will represent the total earned from the diner. It is the product of the earnings per shift and the number of shifts.
Sample Answer: Write the equation using slope and y-intercept in slope-intercept form, y = –275x + 3500. Then, substitute the x and y values of the point into the equation, 1850 = –275(6) + 3500. Simplify to see if both sides are equivalent. Yes, the instructor is correct because both sides are equivalent.
