Answer:
a = 13, b = - 3
Step-by-step explanation:
Expand the left side and compare like terms on both sides
(3x + 1)(x - 2) ← expand using FOIL
= 3x² - 5x - 2
left side = 3x² - 5x - 2 + ax + b ← combine like terms
= 3x² + x(a - 5) + b - 2
right side = 3x² + 8x - 5
For the 2 sides to be equal then
a - 5 = 8 ( add 5 to both sides )
a = 13
and
b - 2 = - 5 ( add 2 to both sides )
b = - 3
Answer:
Step-by-step explanation:
7x -8x = -x
-2 + 10 = 8

We have the following expression:
5/6 + 1 / 4x - y
Let's identify it step by step:
Variables: x and y
Coefficients: 1/4, -1
constant: 5/6
Thus,
The constant is 5/6
Answer:
The following statement is true about the parts of this expression:
The constant is 5/6
Answer:
c. A sample is a small part of a population that represents that population.
Step-by-step explanation:
A sample is a portion of individuals used to collect data, while the population is the total number of individuals. The information from the sample is used to represent the entire population.
Therefore, c is the correct answer.
Answer:
A. 4/12, C. 1/3
Step-by-step explanation:
2/6 can be divided by 3. Therefore, the fraction is 1/3.
A. 4/12 can be divided by 4. This means the fraction will be 1/3. Because 1/3 is equal to 1/3, this option is correct.
B. 1/2 cannot be simplified. Because 1/3 is not equal to 1/2, this option is not correct.
C. 1/3 cannot be simplified. Because 1/3 is equal to 1/3, this option is correct.
D. 3/8 cannot be simplified. Because 3/8 is not equal to 1/3, this option is not correct.
