The answer are B, D and F.
If you solve for x for B, D and F, you'll get (1/2,5)
Answer:
y=5x+13 is the answer
Step-by-step explanation:
so you have to use the y=mx+b method
you plug in 3 for y and -2 for x
3=5(-2)+b,
multiply 5 and -2 to get -10
and it should leave you with 3=-10+b
add -10 to both sides, 10 + 3= 13 and 13 is your b (which is your y-intercept)
13=B
Answer:
252°
Step-by-step explanation:
In the figure attached, the diagram is shown. There, we can see that
∠DOB = ∠AOD + ∠AOC + ∠COB
Replacing with the equivalences: ∠DOB has a measure of 3.5y, the measure of ∠AOD is y, and ∠AOC + ∠COB measure 180°, we get:
3.5y = y + 180°
3.5y - y = 180°
2.5y = 180°
y = 180°/2.5
y = 72°
Therefore, ∠DOB = 3.5*72° = 252°
Answer:
Each page of the album contains 8 cards.
Step-by-step explanation:
Let us assume that each page of the album contains x number of cards.
Now, Mr. Harrid gave each of his two children an equal number of his baseball card collection.
He gave Tony an album with cards on 15 pages and a stack of 25 cards that still need to be put in the album and he gave his daughter Paula an album that has 10 cards and a stack of 65 cards to put in her album.
Therefore, Tony has (15x + 25) cards and Paula has (10x + 65) cards.
Hence, (15x + 25) = (10x + 65)
⇒ 5x = 40
⇒ x = 8
Therefore, each page of the album contains 8 cards. (Answer)
Answer:
3
Step-by-step explanation:
Evaluating the limit of the function 9n - 3n / 2n.
First we factor out n from the numerator of the function to have
F(n) = n(9-3)/2n
Cancelling the variable n at the numerator with the one at the denominator we have:
Iim f(n) = 9-3/2
Iim f(n) = 6/2
Lim f(n) = 3
This shows that the limit of the function given is 3 no matter what the variable x is tending to.
