Answer:
yes
Step-by-step explanation:
If 2 lines are perpendicular then the product of their slopes = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x - 4 ← is in slope- intercept form
with slope m = - 1
5x - 5y = 20 ( subtract 5x from both sides )
- 5y = - 5x + 20 ( divide all terms by - 5 )
y = x - 4 ← in slope- intercept form
with slope m = 1
Thus product of their slopes is - 1 × 1 = - 1
Therefore the lines are perpendicular
Answer:
12 weeks.
Step-by-step explanation:
Amanda starts with $2000 and is getting $150 per week which means that we can make the expression:
The expression is equal to 200 because is the limit where we can arrive to avoid the fee, then the n is the number of weeks that we are looking for:
n=12 weeks
<h2>
Answer:</h2>
This system can be solved for x by elimination.
Now, with what we found for x, we plug it back into one of the equations to solve for y. I chose the second one.
Now, we have our solution.
First identify the a, b, c of the quadratic:
A= -2, B= 0, and C= 3
There’s no b value since there’s no x term, just a constant and an x^2
The square root of (0)^2-4(-2)(3) is equal to 24
18j + 32w = $19.92
14j + 26w = $15.76
