Write y + 1 = –2x – 3 in standard form. question 8 options: a) x + 12y = −2 b) 2x + y = -4 c) -2x-y = 4 d) y = -2x-4

b) 2x + y = -4

Step-by-step explanation:

To go from the Point-Slope Formula [y - y₁ = m(x - x)₁] to the Slope-Intercept Formula [y = mx + b], move -1 to the RIGHT side of the equivalence symbol to get this: y = -2x - 4. Although this is a correct answer choice, this is NOT what the question is looking for because you have to go an extra step further, Standard Formula. To go from the Slope-Intercept Formula to the Standard Formula [Ax + By = C], move 2x to the LEFT side of the equivalence symbol, and you will end up with this: 2x + y = -4. So, your answer is b).

b)

Step-by-step explanation:

We have been given an equation . We are asked to write our given equation in standard form.

We know that standard form of an equation is .

Let us convert our given equation in standard form as:

Therefore, the standard form of our given equation would be .

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
