What is the value of the function at x=−2? y=−4 y equals negative 4 y = 0 y, = 0 y = 2 y = 2, y = 3

Answers

Answer 1
Answer:

Based on the graph which models the function at x = -2 (see attachment), the corresponding y-value is y = 3.

What is a function?

In Mathematics, a function can be defined as a mathematical expression which can be used to define and show the relationship that exist between two or more variables in a data set.

In this scenario, there are several values (points) on the given linear graph expressed as a coordinate (x, y). Hence, the x-values on the x-axis is directly proportional to the y-values on the x-axis.

By critically observing the graph which models the function at x = -2 (see attachment), we can logically deduce that the corresponding y-value is three (3).

A7y2 + 4xy – 3
B7y2 + 8xy – 3
C7y2 + 4xy + 3
D7y2 + 8xy + 3

Answers

(7y² + 6xy) - (-2xy + 3)

⇒ (-1 * -2xy) + (-1 * 3) = 2xy - 3

7y² + 6xy + 2xy - 3

7y² + 8xy - 3  Choice B.

B. 7y2 + 8xy – 3 is the answer

4m + 9 + 5m - 12 = 42

Answers

First, combine like terms.

4m+5m = 9m

9m + 9 - 12 = 42

9-12= -3

9m - 3 = 42

Second, apply the inverse operation to isolate the variable.

9m - 3 = 42
      +3     +3

9m = 45

Third, divide 9 by both sides to solve for m.

(9m)/(9) =  (45)/(9)

m = 45/9

m = 5

Answer:  m = 5
4m+9+5m-12=42 is 5. m= 5.

What is 187.2 divided by 8.

Answers

Answer:

The answer is 23.4 after dividing 187.2 by 8 because in the arithmetic operation we do the addition of numbers, subtraction, multiplication, and division.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

It is given that:

187.2 divided by 8

Mathematically,

= 187.2 ÷ 8

As we know, from the arithmetic operation we do the addition of numbers, subtraction, multiplication, and division.

The two numbers are 187.2 and 8

= 187.2 ÷ 8

After performing the arithmetic operation:

= 23.4

Step-by-step explanation:
