Nancy bought 177 long sleeve and 354 short sleeve shirts.
{x+y=531, y=2x} represents the system of equations for this problem.
Step-by-step explanation:
Let,
x be the long sleeve shirts
y be the short sleeve shirts
Total shirts bought = 531
According to given statement;
x+y=531 Eqn 1
y = 2x Eqn 2
Putting value of y from Eqn 2 in Eqn 1;

Dividing both sides by 3;

Putting x=177 in Eqn 2

Nancy bought 177 long sleeve and 354 short sleeve shirts.
{x+y=531, y=2x} represents the system of equations for this problem.

It looks like they're multiplied, then you can simply add the exponents,
b⁸ * b⁴ = b⁸⁺⁴ = b¹²
remember, b⁸=b*b*b*b*b*b*b*b and b⁴=b*b*b*b
so b⁸ * b⁴ = b*b*b*b*b*b*b*b * b*b*b*b = b¹²
Answer:
(3,10) is not a solution of the given system.
Step-by-step explanation:
Testing the point (3,10) for the system of inequalities, where 3 is the x coordinate, and 10 the y-coordinate, then:

So the point (3,10) is not a solution of the given system.
Let us assume then that the center is the origin. If the major axis is 18, then a = 9 and a^2=81. If the minor axis is 16, then b = 8 and b^2=64. Now you can write the equation. Remember that this ellipse is vertical and so a^2 goes under y^2
