She bought 4 English books and 2 math books
27 x 4 = 108
23 x 2 = 46
108+46=154
Step-by-step explanation:
First, let's move the 
to the right-hand side so we can determine what constant we'll need on the left-hand side to complete the square:
From here, since the coefficient of the 
term is 
, we know the square will be 
(since 
it's half of ).
To complete this square, we will need to add 
to both sides of the equation:
Now we can take the square root of both sides to figure out the solutions to :
Answer: Slope = 3/4 | down 3 over 4
Step-by-step explanation: First I went into desmos graphing calc and then marked the two points (-20,-4) and on a seprete line marked (-12,-10) and then i took a ruler and put up to my screen to see if there was a simplified answer (ex: 2/4 = 1/2) there was not so I just went down to the y line of the 2nd dot which turned out to be 3 and then just counted over to the dot which was 4 units.
