Answer: C 3x + 5y = 1
Solution:
Step 1: To find the equation of line first using both the coordinates given on the graph find the slope using the formula below.
The coordinates are ( -3, 2 ) and ( 2, -1)
m = y2-y1/x2-x1
m = -1-2 / 2- (-3)
m = -3 / 5
Step 2: Now to find line of equation of line we need to find the y intercept using the equation:
y = mx + b
Where
y = y coordinate m = slope x = x coordinate b = y intercept
Choose any one pair of coordinates to find the y intercept. I will be using (2, -1)
y = mx + b
-1 = ( -3 / 5) (2) + b
-1 = -6 / 5 + b ( Don't forget to take the LCM)
-1 = -6/5 + 5b
-5+6 = 5b
1/5 = b
so the equation of line is
y = -3/5 x + 1/5
5y = -3x + 1
3x + 5y = 1
Answer:
2.5
Step-by-step explanation:
the mean, better known as the average, can be found by finding the sum of all numerical data and dividing by the amount of your data. so 1+4+3+2=10 and 10 divided by 4=2.5
Answer:-8
Step-by-step explanation:
The equation used to model the cost of the bracelet would be y = 6c + 12, in which c is the number of charms on the bracelet. This is because even with no charms (c = 0), the bracelet still costs 12, which is the constant.
To solve for how many charms you can get with $96, you can plug 96 in for y and solve.
y = 6c + 12
96 = 6c + 12
84 = 6c
14 = c
1.75 times 12. it is 21. u need $21.00
