Answer (<u>assuming it can be in slope-intercept form)</u>:
Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula, . Substitute the x and y values of the given points into the formula and solve:
So, the slope is 2.
2) Now, use the point-slope formula to write the equation of the line in point-slope form. Substitute real values for , , and .
Since represents the slope, substitute 2 in its place. Since and represent the x and y values of a point the line intersects, choose one of the given points (it doesn't matter which one, the results will equal the same thing) and substitute its x and y values into the formula as well. (I chose (1,2), as seen below.) Then, isolate y to put the equation in slope-intercept form ( format) and find the following answer:
9514 1404 393
Answer:
Step-by-step explanation:
To find the initial amount, put 0 where t is in the formula and do the arithmetic.
A(0) = 523(1/2)^0 = 523(1) = 523
The initial amount is 523 grams.
__
To find the amount remaining after 100 years, put 100 where t is in the formula and do the arithmetic.
A(100) = 523(1/2)^(100/30) ≈ 523(0.0992123) ≈ 52
About 52 grams will remain after 100 years.
He started at the wrong end of the number.
He should have started with the 3-8 and borrowed ending up with 85
Answer:
37.7
Step-by-step explanation:
The orginal answer is 37.699
But you want to round the tenth
So 9 to the 6 you want to rasie the score
6 turns into a 7 and the numbers behind it (9 and the other 9) turn into a zero
37.7 or 37.700
Answer:
Number of drummers in original ensemble
Number of flutists in original ensemble
Step-by-step explanation:
The ratio of flutists to drummers is
Let number of flutists and drummers be and .
As 2 drummers join the group and 6 flutists quit,
Number of drummers =
Number of flutists =
New ratio of flutists to drummers =
So,
So,
Number of drummers in original ensemble
Number of flutists in original ensemble
