Answer:
y = 5x - 7
Step-by-step explanation:
We can make an equation for the perpendicular line by swapping the x- and y-coefficients, negating one of them. Then we can use that form with the given point to see what the constant is.
10x -2y = ...
Removing a common factor of 2 gives ...
5x -y = 5(2) -(3) = 7 . . . . using (x, y) = (2, 3), we can find the constant
Solving for y, we get ...
5x -7 = y . . . add y-7
y = 5x -7 . . . write in the desired form
Answer:
A=1665
Step-by-step explanation:
An area of a rectangle is length times width or l*w=a
First number is length on map and second is the length in reality. Both are in kilometers.
The interest rate is B. 4%
Given:
Principal = 450
Interest = 126
term = 7
rate = ?
Simple Interest is computed by multiplying the Principal, rate, and term.
Interest = P × r × t
126 = 450 × r × 7
126 = 3150r
r = 126/3150
r = 0.04 x 100% = 4%
To check:
I = 450 × 0.04 x 7
I = 18 × 7
I = 126
Answer: 644cents
Step-by-step explanation:
From the question, we were told that
1 pound = $1.79
Miguel bought 3.6 pounds of oranges. This will cost
$1.79 x 3.6 = $6.444
Recall:
$1 = 100cents.
Therefore, $6.444 = 6.444 x 100 = 644.4cents = 644cents. To the nearest cent
