Answer:
x = -1 and y = -1
Step-by-step explanation:
Solve 3x+3y=−6;−x+y=0
Steps:
I will solve your system by substitution.
−x+y=0;3x+3y=−6
Step: Solve−x+y=0for y:
−x+y+x=0+x(Add x to both sides)
y=x
Step: Substitutexforyin3x+3y=−6:
3x+3y=−6
3x+3x=−6
6x=−6(Simplify both sides of the equation)
6x
6
=
−6
6
(Divide both sides by 6)
x=−1
Step: Substitute−1forxiny=x:
y=x
y=−1
Answer:
x=−1 and y=−1
Angle BAC is 45 degrees. The diagonal bisects angle BAD and since all angles in a square are 90 degrees, half of 90 is 45 degrees.

Answer:
The amount of interest earned after a year is $32.25
Step-by-step explanation:
In this question, we are asked to calculate the amount of interest generated by depositing a sum into an account.
To calculate the interest earned, we use the simple interest formula.
Mathematically;
I = PRT/100
where I is the interest earned
R is the rate which is 6.25% according to the question
T is the time taken which is 1 year
P is the amount of money deposited also know. as the principal which is $516
Plugging these values we have
I = (516 * 6.25 * 1)/100 = $32.25
