Answer:
Step-by-step explanation:
Slope intercept form
y + 7 = 3(x + 4) Change all the double minuses to pluses.
y + 7 = 3x + 12 Remove the brackets.
y + 7 - 7 = 3x + 12-7 Subtract 7 from both sides
y = 3x + 5
Slope
Whatever number is in front of the x is the slope Answer: 3
y intercept
Whatever comes after the plus sign (or minus sign) is the y intercept. It is a single number. Answer: 5
x intercept.
This occurs when y = 0
0 = 3x + 5 Subtract 5 from both sides
-5 = 3x + 5 -5
-5 = 3x Divide by 3
-5/3 = 3x / 3
-5/3 = x
Answer: x_intercept = -5/3

Step-by-step explanation:
Given : Jenny studied the characteristics of two species of bacteria. The number of bacteria of species A, A(t), after t hours is represented by the function,
The number of bacteria of species B, B(t), after t hours is represented by the function,
Then, the difference in the number of bacteria, N(t), of both the species after t hours will be :-
Hence, the correct answer should be : D .
Given, a marble factory makes single marbles and then puts them in boxes of 10, cartons of 100 and crates of 1000.
There are 21,650 marbles. We have to find how many boxes, cartons and crates are there.
We have to write 21,650 in the form of 1000, 100 and 10.
We can write 21,650 in the form of 1000 as,
Now there left.
We can write 650 in the form of 100 as,
So there, left.
Now we can write 50 in the form of 10 as, .
So we can write 21,650 as,
So there are 21 crates, 6 cartons and 5 boxes in the marble factory package.
We have got the required answer here.
