The answer for this one would Be B
Distance formula is derived from the Pythagorean theorem. To find the distance between two points (x1,y1) and (x2,y2), all that you need to do is use the coordinates of these ordered pairs and apply the formula to those points. So the formula would be:D=square root symbol(X1-X2)2+(Y1-Y2)2. Hope I've helped you any
Answer:
I believe its C if im wrong delete my question so other people have a chance
Step-by-step explanation:
Answer:
There are 3 lbs of candy in the box.
The caramels are $8 per pound.
12y represents the total cost of truffles in the box.
8x + 12y + 1 represents the cost of caramels in the box + the cost of truffles in the box + the cost of the box.
Step-by-step explanation:
x = the number of pounds of caramels
y = the number of pounds of truffles
x + y = total lbs. and we know x + y = 3
We know x is the number of pounds of caramels.
8x = (cost per pound of caramels) × (number of pounds of caramels)
So 8 = cost of caramels
We know y = number of pounds of truffles. So 12 is the cost of truffles by pound, and 12y is the total cost of truffles in the box.
Based on all the above,
The cost of caramels in the box + the cost of truffles in the box + the cost of the box is = total cost of the box. 8x + 12y + 1 = 30
<h3>Answer: y = (1/2)x+3</h3>
slope = 1/2, y intercept = 3
==============================================================
Work Shown:
Pick any two points you want on the line.
I'll pick the two points (0,3) which is the y intercept and also the point (2,4).
------
Find the slope of the line through (x1,y1) = (0,3) and (x2,y2) = (2,4)
m = (y2 - y1)/(x2 - x1)
m = (4 - 3)/(2 - 0)
m = 1/2 is the slope
slope = rise/run = 1/2
rise/run = 1/2 means rise = 1 and run = 2.
This means we go up 1 unit each time we move to the right 2 units.
-----
Since the slope is m = 1/2 and the y intercept is b = 3, we can say
y = mx+b
y = (1/2)x+3
this is the same as y = 0.5x+3 since 1/2 = 0.5
