Step-by-step explanation:
- 2.3 + (- 5.7)
reminder that + (- ) = -
To obtain - 3.4 it is likely that she added 2.3 to - 5.7
The solution is
- 2.3 - 5.7 = - 8

Two equations can be generated from the equation above, one for Package A and the other for Package B.
(Package A) 3x + 2y = 18
(Package B) 8x + 6y = 50
Solving simultaneously for the values of x and y gives, x = 4 and y = 3. Hence, each birthday card costs $4.
This can be
solved by solving the slope of the line. First let y be the rating of the test
and x be the number of incorrect answers. Slope can be solved using the formula:
M = ( y2 –
y1 ) / ( x2 – x1)
M = ( 90 –
98) / ( 5 -1 )
M = -2
<span>So the model
has a negative slope</span>
