-3y + 12 = -8x

anyone know how to do this. I need it in y=mx+b and Ax+By=C
slope intercept form and standard form

Answers

Change -3y + 12 = -8x to the form y = mx + b

Subtract 12 on both sides

-3y = -8x - 12

Divide by -3 on both sides

y = 8/3 + 4

Change original equation to Ax + By = C

-3y + 12 = -8x

Switch -8x and 12

-3y + 8x = -12

(ps, I haven’t done this kind of math in a long time )

Subtract 5x^2+8x-11 from 3x^2+8x-7

Answers

Answer: -2x^2+4

Explanation: First you’d need to rewrite the equation as (3x^2+8x-7)-(5x^2+8x-11). Then since you are subtracting, distribute the negative to the right side which will then give you -5x^2-8x+11 since you flip the signs. Then simply combined like terms. -5x^2 + 3x^2 is -2x^2. Then 8x-8x is 0 and lastly, +11-7 is 4. So in order, all together, your answer is -2x^2+4.

Mr Chin bought 3.8 kg of candy, nearest to
100g. What is the least amount of candy in the
bag to nearest kilogram.

Answers

To do this you need to find the lower bound
The lower bound is the minimum amount that would round up to the estimated value

3.8kg, measured to the nearest 100g
The degree of accuracy is to the nearest 100g
100/2 = 50g (0.05kg)

Lower bound 3.8 - 0.05 = 3.75kg

Therefore the least amount of candy you could have in the bag is 3.75kg
