Answer:
Step-by-step explanation:
I haven't got time to do all these by I'll give you the method in each case.
You have to make the x or y term equal (or 1 term + and other -) in both equations before adding or subtracting.
A . Multiply equation 2 by 2 and subtract (to eliminate x)
- don't forget to multiply EACH TERM by 2.
B. Multiply equation 2 by -2 and add.
C. Multiply equation 1 by 3 and equation 2 by 2 ( this will give -6y and +6y in the resulting equations ) so you then add to eliminate y.
D. Multiply equation 1 by 13 and equation and equation 2 by 2 to eliminate x then add.
Answer:
(6, 7)
Step-by-step explanation:
rotating a shape 180 degrees will create the same shape, with similar coordinates. Therefore, drawing a straight line through the origin, would make the coordinates of J (6, 7)
Answer:
B. 14 m sq.
Step-by-step explanation:
Area for a triangle
A = W times H times 1/2
4 times 7 = 28
28/2 = 14
In this case were going to solve the question using "simple interst", so since were looking for the interest it will be I= PxRxT (I stands for "interest", P stands for "principal", R stands for "rate" and T stands for "time")
so P is $3000
R is 2%
and T is 3 years
so we'll have to turn our rate into a decimal which is 2% = .02
now to start the problem:
I= (3000)(.02)(3) (means 3000 x .02 x 3)
I= $180 is your answer
