What is an equation of the line that passes through the point (5, 4) and is parallel to
the line 6x – 5y = 15?

Answers

Answer:

6x - 5y does not change as it is parallel so I put x = 5 & y = 4 in this equation and the result is 6 × 5 - 5 × 4 = 30 - 20 = 10 so the parallel equation is 6x - 5y = 10

what is the difference between 4x and x4? evaluate both of these expressions when x = 2

Answers

Answer:

There is no difference. 4x and x4 are both meaning 4 times x and x times 4

Step-by-step explanation:

If x = 2, then 4 x 2 = 8.

x4 is the same thing

2 x 4 =  8

Note:

When the numbers are there together, without an operation, it means multiplication.

The value of the expression 4x is 8.

The value of the expression [tex]x^4[/tex] is 16.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

4x and [tex]x^4[/tex]

For x = 2,

4x = 4 x 2 = 8

[tex]x^4[/tex] = [tex]2^4[/tex] = 2 x 2 x 2 x 2 = 16

Thus,

The values of the expression are 8 and 16.

How do you solve 2(x-6)=x-14

Answers

2(x-6)=x-14
2x-12=x-14
2x -x=-14+12
x= -14+12
x=-2

Answer:

x = -2

Step-by-step explanation:

[2(x-6) = x - 14]

Multiply 2 by x and (-6) in parenthesis, distribution

[2x -12 = x - 14]

Add 12 to both sides

[2x = x - 2]

Subtract x from both sides

[x = -2]

In school ,there are 3 girls for every 2 boys . There are 650 students in total . How many students are girls ?

Answers

Answer:

Girls = 390

Step-by-step explanation:

Set up a proportion:

In a sample of 3:2, you have 5 kids in all.

So the the ratio of girls to kids in a sample of 5 is 2:5.

So set up a proportion:

(3/5) = (x/650)

5x = 650(3)

5x = 1950

x = 390

Answer:

390

Step-by-step explanation:

Let number of boys be b and girls be g. Then we have:

g/b = 3/2g + b = 650

From the first equation b is:

b = 2g/3

Substitute b in the second equation

g + 2g/3 = 6505g/3 = 650g = 650*3/5g =  390
