Write the slope-intercept form of the equation : a) 4x-2y = 3​

Answer:

y = 2x - (3)/(2)

Step-by-step explanation:

slope-intercept form: y = mx + b

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Divisions

Additions

Subtraction

First, subtract 4x from both sides of the equation:

4x (-4x) -2y = (-4x) + 3

-2y = -4x + 3

Next, divide -2 from both sides of the equations:

((-2y))/(-2) = ((-4x + 3))/(-2)

y = (-4)/(-2)x + (3)/(-2)

y = 2x - (3)/(2)

y = 2x - (3)/(2) is your answer.

Question 20Identify the area of the polygon with vertices B (3, 2), C (7,-2), D (2,-4), and E (1, -2).
A = 19 units2
A = 17 units2
A = 30 units
A = 18 units2

Answers

Answer:

  (d)  A = 18 units²

Step-by-step explanation:

Line CE can be considered to be the base of two triangles. It is 6 units long. The upper triangle is 4 units high, and the lower triangle is 2 units high. The formula for the area of a triangle is ...

  A = 1/2bh

Then the sum of the areas of the two triangles is ...

  A = 1/2(6)(4) +1/2(6)(2) = 12 +6 = 18

The area of the polygon is 18 square units.

Answer: A=18units2

Step-by-step explanation:

I said 17 before and got it wrong lol.

Next time I said 18 cuz it seemed like the closest when I estimated what it looked like the units it covered, so it's right:)

hope it helps!
