The answer is:
There are 595 calories in a banana split To find this we first need to set up our equation:

, where x= calories in a banana split

----------------Add 5 to both sides
595=x-------------------Multiply 7 to both sides to get rid of the fraction
So, there are 595 calories in a banana split
Hope this helps! :)
Answer:
Part 1) In the procedure
Part 2) In the procedure
Step-by-step explanation:
Part 1) Observing the graph
The roots are x=-1/2 and x=4
Remember that, the roots are the x-values when the value of y is equal to zero (the x-intercepts)
That's why Sheldon immediately realizes Howard's solution is incorrect
Part 2) we have

The formula to solve a quadratic equation of the form
is equal to
in this problem we have
equate the equation to zero
so
substitute
Howard's error is in this step, is wrong with the sign of the number 7, is positive instead of negative
Answer:
x=2
HPT 3x+5y=6 (1) và 2x+y=4 (2)
Nhân phương trình (2) với 5 để hệ số y của 2 phương trình bằng nhau. Ta có:
(2)⇔ 10x+5y=20(3)
Trừ (3) cho (1), có: 7x+0y=14⇒x=2
