Answer:
y = - 3x + 17
Step-by-step explanation:
Note that slope is a measure of the rate of change of a linear function.
Express the function in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
here m = - 3, thus
y = - 3x + c ← is the partial equation
To find c substitute (5, 2) into the partial function
2 = - 15 + c ⇒ c = 2 + 15 = 17
y = - 3x + 17 ← is the linear function
The first jump is the correct answer I think
Solution :-
Total number of pages in the book = 150
Total number of one digit numbers = From 1 to 9
= 1*9
9 digits
Total number of two digit numbers = From 10 to 99
= 2*90
= 180 digits
Total number of three digit numbers = From 100 to 150
= 3*51
= 153 digits
Total number of digits printed in the book containing 150 pages
= Total number of one digit numbers + Total number of two digit numbers +
Total number of two digit numbers
= 9 + 180 + 153
= 342 Digits
Hence, total 342 digits are printed in the book which has 150 pages.
Answer:
A
Step-by-step explanation:
The inequality 1.25x-6.50>50 says that 1.25 is charged to added per x number of things and that 6.50 is taken away. At the end of this calculation, it must be more than $50. This means B and D are not options because they are always adding not taking away any value. C is not an option because 1.25% converts to 0.0125. As a growth interest it would be 1.0125x not 1.25x. This means A must be the solution.
