Find two numbers whos diffrence is 16 and the product is 720
antiseptic1488 [7]

Answer:

the numbers who's difference is 16 and the product is 720 is

36 &20

Explanation:

to finding numbers you have to express the equation in a quadratic equation then Factor it.

since the two numbers have a difference of 16 you can say that the first number is x and the second number is x -16 then their product is 720.

x(x-16)=720

x²-16x=720

x²-16x-720=0

(x-36)(x+20)

there are two possible value of x but since you are looking for the positive value of x, choose the positive value of x the first number is 20.

To find the second number

x-16=20

x=20+16

x=36

the second number is 36

HELP ASAP!right answer I’ll give you a crown
faltersainse [42]

Answer:

y=-\frac{3}{2}x+1

Step-by-step explanation:

Slope-intercept form means

y=mx+c

where m is given its the slope which is -\frac{3}{2} and we have the coordinates x and y which is (4, -5) and we need to find the value of c which is the y-intercept so we insert all these values into the equation so ,

y=mx+c

-5 = -\frac{3}{2}(4)+c

-5=-6+c

c=1

now we know the value of slope which is given -\frac{3}{2} and we found the value of which is 1 so we put these values into our original slope-intercept form equation

y=mx+c\\\\y=-\frac{3}{2}x+1
