Answer:
y = 7x/8 - 53/8
Step-by-step explanation:
P(3,-4)
x = -7y/8 + 3
Isolate y and translate to slope-intercept form:
y = mx + b
x = -7y/8 + 3
x - 3 = -7y/8
8x - 24 = -7y
y = -8x/7 - 24/7
The slope of the equation is -8/7
The slope of the new equation will be perpendicular to the slope of the given equation which means it is the negative reciprocal.
y = mx + b where m = -1/(-8/7) = 7/8
y = 7x/8 + b
Plug in know values and solve for b:
-4 = 7(3)/8 + b = 21/8 + b
-4 - 21/8 = b
b = -32/8 -21/8 = -53/8
Plug in b into the equation:
y = 7x/8 - 53/8

Hi there!
Here is the step by step explanation to solving this problem :
20% of $1,049
20% is the same thing as 0.2 & the word "of" is the same thing as a multiplication sign :
0.2 × 1,049 = $209.80
1,049 - 209.80 = $839.20 = price after discount
4.25% is the same thing as 0.0425 :
0.0425 × 839.20 ≅ $35.67
839.20 + 35.67 = $874.87
The total cost is : $874.87
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
size
Step-by-step explanation:
Example: (1 0 2) has 1 row and 3 columns, so m = 1 & n = 3 and the size is 1 x 3.
