Perpendicular lines have slopes that are negative reciprocals of each other, so the equation of the line in point-slope form is:
Rewriting this in standard form,
Answer:
0=0
infinitely many solutions
Step-by-step explanation:
plug x=2y+3 as x into 3x-6y=9...so
3(2y+3)-6y=9, which has our x=2y+3 plugged in because that is what x equals
if you solve its
6y+9-6y=9
0y=0
y=0
making it 0=0
you can't go further from this
Answer:
The solution for 
is all real numbers less that or equal to 36.
Step-by-step explanation:
Given expression:
To find the solution for
Solution:
In order to solve for , we will make sure to isolate the unknown variable on left side alone by doing math operations on both sides of the inequality.
We have:
Multiplying both sides by 2.
The 2 on left side will cancel each other leaving alone.
Thus, we have:
Thus, solution for is all real numbers less that or equal to 36.
Answer: $16.60
Step-by-step explanation:
5.80+ 3.60= 9.40+ 3.60= 13.00+ 3.60= 16.60
So after 4 weeks he earned $16.60
Answer:
Final cost = $3070.90
Step-by-step explanation:
First we need to find the discount
Discount = original price * percent off
Discount = 2200 * .15
Discount = 330
Sale price = original price - discount
Sale price = 3200-330
Sale price = 2870
Now we need to calculate tax
Tax = sales price times tax rate
Tax = 2870 * .07
= 200.90
Final price = sales price plus tax
Final price = 2870 + 200.90
3070.90
