For lines to be perpendicular their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1, and in this case:
-m/4=-1
-m=-4
m=4, so the slope of the perpendicular line is 4 so we have thus far:
y=4x+b, using point (-4,3) we can solve for the y-intercept, "b"
3=4(-4)+b
3=-16+b
19=b, so our line is:
y=4x+19
105% =$34.02
100% (cost without sales tax) = 34.02/1.05 =$32.40
Answer:
Option 4: y > 2x
x + 2y < -8
Step-by-step explanation:
Taking first equation:
y > 2x
Putting x = 0
y > 0
Putting y = 0
0 > x
So the blue line in drawn according to first equation.
Taking second equation:
x + 2y < -8
Putting x = 0
2y < -8
y < - 4
putting y = 0
x < -8
So the red line is drawn accordingly.
i hope it will help you!
Answer:
A = 63 m^2
Step-by-step explanation:
The area of a parallelogram is bh
A = bh
The base is 9 and the height is 7
A = 9*7
A = 63 m^2
Answer:
B.
Step-by-step explanation:
The purpose of establishing a good credit history is to show that you are able to handle money. The higher your credit score is, the more responsible you are with money.
You can build good credit history by making payments with a credit card and repaying your purchases. It shows that if the bank were to give you a larger sum of money, you would pay it back.
As such, B is incorrect. The purpose of credit relates to purchases. A is obviously correct for this reason. C is correct because banks are likely to put less interest, as interest correlates to the score (lower credit score, higher interest). D is correct because banks allow you to obtain credit cards with better rates if your credit score is high enough.
Employers cannot determine your qualification for a job based on a credit score. Some states even prohibit this. For this reason, B is incorrect.
