Answer:
(-2,0)
Step-by-step explanation:
To find the x intercept, set y =0 and solve for x
9x+3y = -18
9x +0 = -18
9x/9 = -18/9
x = -2
(-2,0)
You go down to the negative number x is first and then you go to the positive number which is y
Answer: Derivative or y = mx + b
Step-by-step explanation:
Take the m value from the standard form equation:
y = mx + b
Or, the second way, is to take the derivative of the function and plug in your x value for your slope.
The derivative of a linear function is very easy to take, so it boils to preference
Part A:
The area of the rectangle will be the length times the width, so 4•(x+3). Using distributive property, you'll multiply every term inside the parentheses by 4.
The area of the rectangle can be expressed by 4x+12.
Part B:
Multiply 4•2 and (x+3)•2, then multiply them together.
8(2x+6) Now use distributive property to find your answer simplified.
16x+48 is your answer
