Answer:
f(-5)=30
Step-by-step explanation:
in this scenario you want to plug in -5 for x which will give you an equation of f(-5)=(-5)^2+5 which evaluates to 30
I think your answer is D because when you solve for K by simplifying both sides of the equation you get k>-10 so D would be your answer
Answer:
y=-2x+15
Step-by-step explanation:
First, write out the equation in slope-intercept form, with what you already have:
![y=-2x+b](https://tex.z-dn.net/?f=y%3D-2x%2Bb)
Let "b" represent the y-intercept.
To find the y-intercept, substitute the point (6,3) in for the "x" and "y" variable of the equation and solve for "b":
![3=-2(6)+b\\3=-12+b\\3+12=-12+12+b\\15=b](https://tex.z-dn.net/?f=3%3D-2%286%29%2Bb%5C%5C3%3D-12%2Bb%5C%5C3%2B12%3D-12%2B12%2Bb%5C%5C15%3Db)
Therefore, your y-intercept is 15.
That means your equation is slope-intercept form <em>is</em> y=-2x+15.
