me need slope and y intercept to get it in y=mx+b form (slope intercept)
Slope is the
difference in y / differences in x
differences in y = 6.5 -3 = 3.5
difference in x = 2 - 1 = 1
so slope is 3.5/1 or just 3.5
(now you can see the answer is c but lets check it by getting the y intercept too)
y intercept
this is when x is 0
the lowest x we see is 1 so if I go bacl to 0 in x the y must for back 3.5
3-3.5 is -0.5
so equation is y=3.5x -0.5 so the closest is c
The ratio is 3:2, purple :green
The bag has 21 purple so to get from 3 to 21 it is multiplied by 7; so we must also multiply the 2 by 7 to keep the ratio balanced.
21:14
Answer:
x² -3/4x +1/4 = 0
Step-by-step explanation:
Consider the two equations in factored and expanded forms:
(x -p²)(x -q²) = x² -(p²+q²)x +p²q² = 0 ⇒ p²+q² = 1, p²q² = 16
and
(x -1/p)(x -1/q) = x² -(1/p+1/q)x +1/(pq) = 0
Consider the squares of the sum and product of roots:
constant term: (1/(pq))² = 1/(p²q²) = 1/16 ⇒ 1/(pq) = √(1/16) = 1/4
x-term: (1/p +1/q)² = (p +q)²/(pq)² = (p² +q² +2pq)/(p²q²)
= (p² +q²)/(p²q²) +2/(pq)
= 1/16 +2/√16 = 9/16 ⇒ (1/p +1/q) = √(9/16) = 3/4
Then the equation with roots 1/p and 1/q is ...
x² -3/4x +1/4 = 0
Answer:
it is C (4,2) you need to add from 0 to the 5 in yxis then its 4 and in x axis when u go the the right like going up then it is 2 not -2 or whatever
Answer:
The Answer is 1
Step-by-step explanation:
It's 1 because x is -3 and its getting squared so its -3 times -3 which is 9. And then Y is -2 cubed so -2x-2x-2 which equals -8.
9-8=1
Hope this helps!
