Number 6 is A the slope of the graph is -1 and the starting point is seven, so that means your equation is y = -1x +7, it can also be written as y=-x+7

Number 7 is C if I’m not mistaken, because as the absent goes up the dots for grade point average goes down

Number 8 is A, because as more missing assignments goes up your grade will go down meaning it will be negative

the product of two consecutive integers n and n+1 is 42. what is the positive integer that satisfies the situation?
MrMuchimi
n(n+1)=42 \\
n^2+n=42 \\
n^2+n-42=0 \\ \\
a=1 \\ b=1 \\ c=-42 \\ b^2-4ac=1^2-4 \times 1 \times (-42)=1+168=169 \\ \\
n=\frac{-b \pm \sqrt{b^2-4ac}}{2a}=\frac{-1 \pm \sqrt{169}}{2 \times 1}=\frac{-1 \pm 13}{2} \\
n=\frac{-1 -13}{2} \ \lor \ n=\frac{-1+13}{2} \\
n=\frac{-14}{2} \ \lor \ n=\frac{12}{2} \\
n=-7 \ \lor \ n=6

The positive integer is 6.
The consecutive integers are 6 and 7.

How to solve: dy/dx=e^(x-y), y(0)=ln3
ella [17]
Hello,

\dfrac{dy}{dx} = \dfrac{e^x}{e^y} \\

e^y*dy=e^x*dx \\

e^y=e^x+C\\

if\ x=0\ then\ y=ln(3) ==\ \textgreater \  3=1+C==\ \textgreater \ C=2\\

\boxed{y=ln(2+e^x)}\\
