Answer:
B
Step-by-step explanation:
If (x + h) is a factor of f(x) then f(- h) = 0
Here q(- 1) = 0 , hence (x + 1) is a factor of q(x) → B
Answer:
48 uniforms
Step-by-step explanation:
1836-612=1224.
1224/25.50=48.
Checked answer:
25.50 x 48= 1224
Answer:
.35 x + .70 (20) = .45(x+20)
50=x
Step-by-step explanation:
Let x = liters of 35% salt solution
We have 20 liters of 70%
We have a total of 20+x liters of 45%
.35 x + .70 (20) = .45(x+20)
Distribute
.35x + 14 = .45x +9
Subtract .35x from each side
14 = .10x +9
Subtract 9 from each side
5 = .10x
Divide each side by .1
5/.1 = x
50=x
Answer: cant can, can can, cant cant
Step-by-step explanation:
d(x) = { (x,y): y = sqrt(x) and y >=0 }
since sqrt function requires x to be >=0 so
<u>x >= 0</u>
