Answer:
The y-intercept in coordinate form is (0, 4.5) and represents the taxi pick-up fee. The equation is y=1.5x + 4.5.
Step-by-step explanation:
This question is asking for the slope and y-intercept of a linear equation. A linear equation makes a straight line based on a constant rate of change. For this problem, the cost per mile is the slope, while the independent variable 'x' is the number of miles and the dependent variable 'y' is the total cost. In order to first find slope, you need to use the two points given (7, 15) and (10, 19.5) to set up a change in y / change in x, or (19.5-15)/(10-7) or 4.5/3 which is 1.5. So the slope, or cost per mile is $1.50. To find the y-intercept (b), or the cost of the pick-up fee, simply fill in your equation y=1.5x + b with your other variables and solve for 'b'. So, 15 = (1.5 x7) + b. or 15 = 10.5 +b, subtract 10.5 from both sides of the equation to get b=4.5.
Answer:
x = 30
Step-by-step explanation:
x/2 = 12 + 3
x = 2(12+3)
x = 30
It = 283.68 I just hate these problems but the answer if its a decimal will always be lower then the number your multiplying
Let us assume the small integer to be = x
Then
The second consecutive greater integer = x + 1
The sum of two consecutive integers is already given in the question and it is 125. based on this given information, the answer to the question can be easily reached.
So
x + x+ 1 = 125
2x + 1 = 125
2x = 125 - 1
2x = 124
x = 124/2
= 62
Then
The largest of the two integers = x + 1
= 62 + 1
= 63
So 63 is the largest integer among the two consecutive integers. I hope the procedure is not very tough for you to understand.
