Can someone me with these questions i will put 25 points if you me asap

To find the inverse, interchange the variables

so the Answer is 4 - 1 (x) = - 5 + 2x well thats your answer Hope this helps :)

Step 1:Replace f (x) with y

so y = x + 5 and the denominator 2

Step 2:Interchange the Variables x = y + 5 but the denominator stays the same

Now solve for y

since y is on the right of the equation switch sides so its on the left side

Step 3:y + 5 and the denominator 2 equals x

Step 4: Still solve for y Which is y = - 5 + 2x

Step 5: Solve for y and replace with 4 - 1 (x) to show the final Answer

Now the Answer is 4 - 1 (x) = - 5 + 2x

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
