Pre-calc: Write a degree 3 polynomial with zeros 2, 4, -3

x³-3x²-10x+24

Step-by-step explanation:

Ha, you're in luck; I just learned this last week

Zeros: 2, 4, -3

(x-2)(x-4)(x+3) (I will be multiplying the zeros 2 and 4 first)  ——Distributive Property

(x²-4x-2x+8)(x+3) ––Combine like terms

(x²-6x+8)(x+3) ––Distibutive Property

x³+3x²-6x²-18x+8x+24 ––Combine like terms

x³-3x²-10x+24 ––Final answer, to the third degree

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
