I'm sorry but I couldn't really get that can u at least take a picture or something
Answer:
5x^2 -6x +1
Step-by-step explanation:
(3х^2 – 2) + (2х^2 – бх + 3).
Combine like terms
(3х^2 + 2х^2 – бх + 3-2)
5x^2 -6x +1
Answer:
Given the domain, the range for 3x-y = 3 is {-9, 6, 9}
Step-by-step explanation:
First you have to put the relation in terms of y ⇒ 3x - y = 3⇒ 3x -3 = y
⇒ y = 3x - 3.
Then you replace the values indicated by the domain to find their "y" values (the ones that constitute the range).
f(-2) = -9
f(2) = 6
f(4) = 9.
Finally, the range for the given domain is {-9, 6, 9}

let's find AB
AB=square root of 2^2+3^2
AB=square root of 13
cosO=2/sqrt13
sinO=3/sqrt13
tgO=3/2
ctgO=2/3
Answer:
10m/s,15m/s,20m/s,5m/s
Step-by-step explanation:
Speed = distance / time
a) distance = 100m , time = 10s
Speed = distance / time
Speed = 100m/10s
Speed = 10m/s
b) distance = 300m , time = 20s
Speed = distance / time
Speed = 300m/20s
Speed = 15m/s
c) distance = 700m , time = 35s
Speed = distance / time
Speed = 700m/35s
Speed = 20m/s
d) distance = 1000m , time = 200s
Speed = distance / time
Speed = 1000m/200s
Speed = 5m/s
