Solve for y
eliminate x
multiply firs tequation by -5 and 2nd by 3 and add them
-15x-30y=-15
<u>15x-3y=81 +</u>
0x-33y=66
-33y=66
divide both sides by -33
y=-2
the y coordinate is y=-2
Your answer would be:
Formula: I = P * r * t
P = Principle $5000
R = Rate 2.5% per year, or in decimal form, 2.5/100 =0.025
T = Time involved 7 years time period
I = Interest
Part A:
P = 5000
R = 2.5%, or .025
Part B: Riley To find the simple interest, we multiply
I = 5000 * 0.025 * 7
T = 7
The Interest is = $875.00
Part C: Investment Balance = Investment + Interest
Usually the interest is added onto the principal t figure out the new amount after 7 years.
= $5000.00 + $875
= $5875.00
Ex. if you borrowed $5000, you would now owed $5875.00
Hope that helps!!!
<span>A circle whose center is located at point (a, b) having a radius of length r has the equation:
(x -a)² + (y -b)² = r²
Therefore the radius = sq root (16) which = 4

No because it is not equaivalent to each other
Answer:
x= -45/4 or -11.25 or -11 1/4
Step-by-step explanation:
