Part A
The estimated cost of the fabric is 80 all together and the real cost is $72.14
consecutive even integers are 2 apart
so they are x and x+2
their sum is x+x+2
the sum is -50
so x+x+2=-50 would be the equation
we can simplify it to get 2x+2=-50
the answer is the 3rd option
To find what the y value is, we just have to input the x value and solve.
y =
x + 2
y =
* 2 + 2
y =
+ 2
y = 3.2
That means that the missing half of the coordinate is
3.2.
