Answer:
3/-2
Step-by-step explanation:
(3x) km/3 -2x=4 (x3) times 3 on both sides because you need to get the x by itself and your dividing so the opposite of dividing is multiplying.
9km - 2x = 12
-9 -9 subtract on both sides
-2x = 3
-2 -2 divide on both sides.
so x= 3/-2
I'm in algebra too, and i'm relearning it, so hope i have helped you in anywy and if i haven't I'm sorry.
Answer:
3
Step-by-step explanation:
3.4 4 isnt bigger than 5 so it goes to 0 which makes it 3
Answer: f(x) = 4 if -1 ≤x ≤ 1
f(x) = x - 1 if 3≤ x ≤ 5
Step-by-step explanation:
if -1 ≤x ≤ 1
We can see that in this range the function is constant, f(x) = 4
if 3≤ x ≤ 5
In this region we can see a linear relationship, with the points (3, 2) and (5, 4)
as the extremes, we can find the slope of this linear equation as:
s = (4 - 2)/(5 - 3) = 2/2 = 1
So our equation is
f(x) = 1*x + b
to find the value of b we can evaluate our function in the first point, we know that when x = 3, y = 2, so we have:
2 = 1*3 + b
b = 2- 3 = -1
then f(x) = 1*x - 1
Then we have:
f(x) = 4 if -1 ≤x ≤ 1
f(x) = x - 1 if 3≤ x ≤ 5
I don’t know i just need to answer questions
Answer:
4y
Step-by-step explanation:
5y+18y-(-2y)+(-10y)
5y+18y+2y-10y
15y+4y=19y
