Answer:
Cost of the coat = $54
Step-by-step explanation:
Given:
She saved = $ 9
To Find:
Cost of the coat = ?
Solution:
Let the price of coat be x
She saved $9
and according to given condition it is 1/6 of the total money she needs for buying coat
by this we have
Multiplying both sides by 6
it becomes
x = 9*6
x = $54
As x is the amount she needs
so
Cost of the coat = $54
Answer:
Step-by-step explanation:
First create an equation in slope-intercept form, y = mx + b. To do this, find the rate of change or slope (m), and the y-intercept (b).
Using two pairs, (-7, -3) and (-8, -4),
m = 1
To find b, substitute m = 1, x = -7 and y = -3 into y = mx + b.
Thus:
-3 = (1)(-7) + b
-3 = -7 + b
-3 + 7 = b
4 = b
b = 4.
Replace y with f(x), m with 1 and b with 4 in y = mx + b.
The function would be:
