Answer:
I think it is 2, downwards
First of all, you have to calculate slope of that,
m = (y2-y1)/(x2-x1) = (2-0)/(1-(-1)) = 2/2 = 1
Equation would be y-y1 = m(x-x1)
y-2 = 1(x-1)
y-2 = x-1
y = x+1 .... it is the final equation
(3)
as 4x + -3^3 + 212
(Coefficient of the leading x is 4 and the power of the highest power term is 3) (it isn’t in correct polynomial form, however)
Answer:
160 total beads
Step-by-step explanation:
so if 1/4 of the beads are red, then 3/4 of them are not.....so 3/4 is the remainder of beads.....and 3/5 of the remainder are yellow....so 3/5 of 3/4 =
3/5 * 3/4 = 9/20...so 9/20 are yellow.....and the rest (48) are blue.
1/4 + 9/20 = 5/20 + 9/20 = 14/20 reduces to 7/10...so 7/10 of the beads are red and yellow
so if 7/10 of the beads are red and yellow, then 3/10 are blue
3/10 of what number is 48
3/10x = 48
x = 48 * 10/3
x = 480/3
x = 160
let me check it..
1/4 are red......160 total beads.....so red beads = (1/4 * 160) = 160/4 = 40
3/5 of the remainder is yellow.....so 3/5 of (160 - 40) = 3/5(120) = 72 yellow
and then u have 48 blue...
40 + 72 + 48 = 160
so there are 160 total beads.......40 red, 72 yellow, and 48 blue <===
