A line has this equation: y= -9x-2Write an equation for the parallel line that goes through (2, -3).

Answers

Answer 1

Answer:

Answer:

y = - 9x + 15

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 9x - 2 ← is in slope- intercept form

with slope m = - 9

Parallel lines have equal slopes, thus

y = - 9x + c ← is the partial equation

To find c substitute (2, - 3) into the partial equation

- 3 = - 18 + c ⇒ c = - 3 + 18 = 15

y = - 9x + 15 ← equation of parallel line

Answer: 12

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First we need to substitute the value of the variable into the expression and simplify.

b-(b+a×4c÷4) = 1 - (1 + -6 × 4(2) ÷ 4).

Now we need to solve 1 - (1 + -6 × 4(2) ÷ 4).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1 - (1 + -6 × 4(2) ÷ 4)

| First, we cancel out 4 and 4.

1 - (1 - 6 × 2)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Next, we multiply -6 and 2 to get -12.

1 - (1 - 12)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Then we subtract 12 from 1 to get -11.

1 - (-11)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The opposite of -11 is 11.

1 + 11.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Add 1 and 11 to get, you guessed it, 12!

The product of 8 and the sum of 4 and a number is 112. What is the number?Which equation could be used to solve for the number?
8 + 4n = 112
8 x 4 + n = 112
8(4 + n) = 112

Answers

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The equation that is used to solve the number for the statement "the product of 8 and the sum of 4 and a number is 112" is

8(4 + n) = 112.

The number n is 10.

Option C is the correct answer.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

3x + 4 = 5 is an equation

3x + 9 is an equation.

We have,

The product of 8 and the sum of 4 and a number is 112.

Let the number be n.

We can write as:

8 x (4 + n) = 112 _____(1)

8 x 4 + 8 x n = 112

32 + 8n = 112

Subtract 32 on both sides.

8n = 112 - 32

8n = 80

Divide both sides by 8.

n = 10

The number is 10.

We can cross-check

8 x (4 + 10 ) = 112

8 x 14 = 112

112 = 112

Proved.

Thus,

The equation that is used to solve the number for the statement "the product of 8 and the sum of 4 and a number is 112" is

8(4 + n) = 112.

The number n is 10.

#SPJ5

8(n + 4) = 112
8(n) + 8(4) = 112
8n + 32 = 112
- 32 - 32
8n = 80
8 8
n = 10

The answer is C.
