Answer:
The slope is -0.5 or -1/2
Step-by-step explanation:
the slope of a line is easily calculated by hand using small, whole number coordinates. The formula becomes increasingly useful as the coordinates take on larger values or decimal values.
It is worth mentioning that any horizontal line has a gradient of zero because a horizontal line has the same y-coordinates. This will result in a zero in the numerator of the slope formula. On the other hand, a vertical line will have an undefined slope since the x-coordinates will always be the same. This will result the division by zero error when using the formula.
The system of equations that represent the cost of x shirts, and y pairs of pants are 4x + 3y = 85.50 and 3x + 5y = 115.00. Option (a) is correct.
A system of equations or an equation system is a collection of simultaneous equations.
Given that Shopping at Saver Mart, Lisa buys her children four shirts and three pairs of pants for $85.50 and She returns the next day and buys three shirts and five pairs of pants for $115.00
Now we have to find the system of equation
Lisa buys her children four shirts and three pairs of pants for $85.50 is given by
4x + 3y = 85.50
She buys three shirts and five pairs of pants for $115.00 is given by
3x + 5y = 115.00
Therefore the system of equations that represent the cost of x shirts, and y pairs of pants are
4x + 3y = 85.50 and 3x + 5y = 115.00

Step-by-step explanation:
Applicants can be filled by equal numbers thus 5 applicants can cover per shift
531,441
solution:
Multiply.
(9²)³
Multiply 9².
9 x 9
9² the 2 means multiply to itself.
so 9x9 is equal to (81)³
Now multiply it again
81 x 81 x 81
= 531,441
