Answer:
y = 14
Step-by-step explanation:
move 5y over to the left and you should get -2y +6=-18. subtract 6from both sides and you will now have -2y=-24. divide bothe sides from -2 and you will get y=14

The value of the expression [(114−34)⋅(−23)3]÷(−4) is equal to the fraction 5451/4 or the mixed fraction 1362 whole number, 3/4.
<h3>Evaluation for the expression considering PEDMAS</h3>
P – Parenthesis First: B – Brackets First
E – Exponents
D – Division
M – Multiplication
A – Addition
S – Subtraction
We evaluate the expression [(114−34)⋅(−23)3]÷(−4) as follows;
114 - 34 = 79
-23 × 3 = -69
so;
[(114−34)⋅(−23)3] = 79 × −69
[(114−34)⋅(−23)3] = −5451
[(114−34)⋅(−23)3]÷(−4) = −5451/−4
divide through by the common factor −1
[(114−34)⋅(−23)3]÷(−4) = 5451/4
Therefore, the simplified value for the expression [(114−34)⋅(−23)3]÷(−4) is the fraction 5451/4 or the mixed fraction 1362 whole number, 3/4

The generic equation of the circle is given by:
Where,
r: radius of the circle
(xo, yo): center of the circle.
The center of the circle in this case is:
The radius of the circle is:
Substituting values we have:
Rewriting the equation we have:
Answer:
The general form of the equation of a circle with center at (a, b) and radius of length m is:
option A
Answer:
a = 1, b = -8
Step-by-step explanation:
you need complete the square to get a and b:
x^2+2x(+1)-7(-1)
by adding and subtracting 1 you aren’t changing the equation because 1-1=0
then u could simplify the equation to
(x+1)^2 - 8 to get a=1 and b=-8
