Step-by-step explanation: 4x - 5 =7

4x -5 + 5=7+5

4x=12

4x-4=12 divided by 4

x= 3

Answer 2

Answer:

A and D

Step-by-step explanation:

When you have an equation that has an x on one side with other things you do the opposite of the thing on the same side as the x. You would add 5 to 17 then you would divide by 4 to seperate the four from the x.

In functions one input has only one output. Since 3 has two outputs it is not a function.

Which expression is equivalent to 8c + 6 - 3c - 2 ?

A)5c + 4

B)5c + 8

C)11c + 4

D)11c + 8

Answers

Answer:

I believe the answer is 5c + 4.

Step-by-step explanation:

The first step in simplifying expressions like this is to combine the values with the same coefficient and rearrange them so that they are next to each other in the expression. When you do this, you also have to keep the operation that comes before it if possible. 8c + 6 -3c - 2 will be turned into 8c - 3c + 6 - 2. Now you can simplify the expression in different parts. 8c - 3c = 5c, and 6 - 2 = 4. Keep the addition operation in the middle and combine the numbers:

5c + 4.

a The relation is a function.

It is B and D because it is the only one that matches the input and outputs. D shows a perfect graph of the points while B shows the points themselves. They cannot be a linear function since they are not linear so it is not E or F.

x2-16= -2x - 1

Please help

Answers

The solutions are -5 and 3.

Step-by-step explanation:

[tex]x^2 - 16 = -2x-1[/tex]

[tex]x^2 - 16 +2x+1=0[/tex]

[tex]x^2 +2x-15=0[/tex]

Factoring the quadratic expression:

[tex](x+5)(x-3)= x^2 +2x-15=0[/tex]

Explanation:

The number of boys and girls in a class are in the ratio 4 : 7. There are 15 more girls than boys. find the number of total students in the class

Answers

Answer:

The number of total students in the class is 55

Step-by-step explanation:

We will use the ratio method to solve the question

∵ The number of boys and girls in a class are in the ratio 4: 7

∵ There are 15 more girls than boys

→ That means the difference between them is 15

∵ The difference between the terms of their ratio = 7 - 4 = 3

→ By using the ratio method

→ boy : girl : difference

→ 4 : 7 : 3

→ x : y : 15

→ By using cross multiplication

∵ x × 3 = 4 × 15

∴ 3x = 60

→ Divide both sides by 3

∴ x = 20

∵ y × 3 = 7 × 15

∴ 3y = 105

→ Divide both sides by 3

∴ y = 35

∵ x represents the number of boys

∴ The number of boys is 20

∵ y represents the number of girls

∴ The number of girls is 35

∴ The total number of students = 20 + 35 = 55

∴ The number of total students in the class is 55

The second option, 2 is a prime number, but not odd

Step-by-step explanation:

A prime number is a result of two other whole numbers multiplied by themselves. There is no whole number that you can multipy by itself to get 2 because 1 × 1 = 1 and 2 × 2 = 4. Therefore, it is a prime number. But, that does not mean it is an odd number because odd numbers are 1, 3, 5, 7, etc. and even numbers are 2, 4, 6, 8, etc.
