Answer:
2
Step-by-step explanation:
Given the average rate of change formula, we must first find the x and y values of the function.
We are provided with the two x values, 1 and 2. We now need to find the output, or y.
ƒ(x)=3^x-4x
ƒ(1)=3-4=-1
ƒ(2)=9-8=1
Then, we use the formula (ƒ(2)-ƒ(1))/x2-x1(subscripts here, in case you multiplied) which gets us 2/1, or 2. Therefore, the average rate of change(ARC) is 2. I believe you just need to find the output and subtract if they are exactly one whole number apart, but don't quote me on that.
Answer:
d
Step-by-step explanation:
all of the angles add up to equal 180 so we setup the equation as 45+3x=180
first you subtract each side by 45
135=3x
then you divide each side by 3 and get that
x=45
