−4x+18>2x+12
−4x​+18−18>2x+12−18
−​4x−2x>2x−6−2x

−​6x>−6
Multiply both sides by −1 and reverse the inequality
(​−6x)(−1)<(−6)(−1)
6x<6
x<1
In interval notation (-∞, 1)

Find the slope of the line passing through the points (7, -2) and (3, - 7).
professor190 [17]

Answer:

m = \frac{5}{4}

Step-by-step explanation:

To find the slope, we have to use the slope formula:

m = \frac{y_2 -y_1}{x_2 - x_1}.

Let (x_1,y_1) = (7, -2) and (x_2,y_2) = (3, -7). Then

m = \frac{(-7)-(-2)}{3-7} = \frac{-5}{-4} = \frac{5}{4}

Solve for x. 3x/2 = 15 x = 22 1/2 x = 10 1/2 x = 10 x = 1/10
Leokris [45]

Answer:

x = 10

Step-by-step explanation:

(3x)/2 = 15 is your question.

Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS (Parenthesis, Exponent (& roots), Multiplication, Division, Addition, Subtraction).

First, multiply 2 to both sides

((3x)/2) = (15)(2)

3x = (15)(2)

3x = 30

Next, to isolate the variable (x), divide 3 from both sides

(3x)/3 = (30)/3

x = 30/3

x = 10

x = 10 is your answer
