Solve for x
3(x - 4) - 2x = 6

Answer:

m = -12

Step-by-step explanation:

everything is ok til the 3rd equation line

-15m - 30 = -12m + 6

-30 - 6 = -12m + 15m

-36 = +3m

-36/3 = m--------> 3 x -12 = - 36

-12 = m

Answer:

9 dollars

Step-by-step explanation:

12+16+8 is 36, 45-36 is 9 :)

Answer:

Using common knowledge each song is about 2 minutes and 50 seconds, so you can listen to about 100 songs, maybe more

Step-by-step explanation:

6-10=4hrs

4 hours divided by 2:50=

4 hours= 280 Minutes, 2:50 can be rounded to 3min, 280/3=93.3333333333

In other words, you can estimate to 94.

So the answer should be around 94

Answer:

y = 2x - 12

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 )

Here m = 2 , then

y = 2x + c is the partial equation

To find c substitute (7, 2 ) into the partial equation

2 = 14 + c ⇒ c = 2 - 14 = - 12

y = 2x - 12 ← equation of line

Answer:

[tex]x>17[/tex]

Step-by-step explanation:

We can treat an inequality just the same as an equality in terms of manipulation!(This doesn't hold for multiplying or dividing by negative numbers, but it holds for all addition).

So, we can add [tex]7[/tex] to both sides of the inequality to get [tex]x-7+7>10+7[/tex].

We can simplify [tex]-7+7[/tex] into [tex]0[/tex], and [tex]10+7[/tex] into [tex]17[/tex].

So, the answer is [tex]\boxed{x>17}[/tex] and we're done!

-14n⁴ + 7n² + 8n + 7

Step-by-step explanation:

(8n - 3n⁴ + 10n²) - (3n² + 11n⁴ - 7)

= 8n - 3n⁴ + 10n² - 3n² - 11n⁴ + 7

= -3n⁴ - 11n⁴ + 10n² - 3n² + 8n + 7

= -14n⁴ + 7n² + 8n + 7

Answer:

$850

Step-by-step explanation:

you multiply 7 x 100 because there are 7 days in 1 week. That equals 700 plus 150 equals 850

Sam currently has $150 in a savings account and is saving 10$ per week. equation  y=150+10x represents the situation.

Two or more expressions with an Equal sign is called as Equation.

Given, sam currently has $150 in a savings account and is saving $10 per week.

The total amount of savings in dollars is represented by y.

x represents the number of weeks

The equation y=150+10x.

y equal to one hundred and fifty plus ten times of x.

Hence, Sam currently has $150 in a savings account and is saving 10$ per week. Equation  y=150+10x represents the situation.

Complementary Angles:

Two angles are called complementary angles, if their sum is one right angle i.e. 90°.

Each angle is called the complement of the other.

Example, 20° and 70° are complementary angles, because 20° + 70° = 90°.

Clearly, 20° is the complement of 70° and 70° is the complement of 20°.

Thus, the complement of angle 53° = 90° - 53° = 37°.

Answer:

(2n+3)+n=90°

2n+3+n=90°

3n+3=90°

3n=90-3

3n=87

n=29°

(2, -3)

Step-by-step explanation:

Your answer was in the question, just apply the rule that was given (x, -y).

The coordinates of C(2, -3).

A reflection is a type of transformation that involves flipping a shape, known as the preimage, across a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you turned the form across the line to graph a reflection.

Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point.

Given:

The Rule for reflection is  (x,y) =(x,-y).

As, the coordinates C(2, 3).

Now, after applying the reflection the coordinate of C become

c(2, 3) ----> C(2, -3).

Hence, the coordinates of C(2, -3).

Answer:

point slope form: y + 4 = 3/8 (x + 5)       slope intercept: y = 3/8x - 17/8

Step-by-step explanation:

y2 - y1 / x2 - x1

-1 - (-4) / 3 - (-5)

slope = 3/8

y + 4 = 3/8 (x + 5)

y = 3/8x + b

-1 = 3/8(3) + b

-1 = 9/8 + b

-17/8

y = 3/8x - 17/8
