$12.25 pen set; 60% discount

1 answer:

6 0

As you want a 60% discount, you must find 40% of $12.25.

40% of $12.25 is the same as 2/5 of $12.25.

Now, 12.25 / 5 = 2.45

And, 2.45 x 2 = 4.90

--------------

This means that 60% off $12.25 is $4.90.

Write a linear function f with the values f(0)=−3 and f(7)=11.

kotegsom [21]

Answer: f(x)= 2x -3

Step-by-step explanation:

Using the given information we can come up with two points that will be use to find the slope and y-intercept.

If you input 0 you get -3 so the point will be (0,-3)

If you input 7 you get 11 so the point will be (7,11)

Now use the points to find the difference in their y coordinates and divide it by the difference in their x coordinates to find the slope.

y coordinates: -3 - 11 = -14

x coordinates: 0 - 7 = -7

-14/-7 = 2

Since the slope is two, we will use the slope intercept formula (y = mx +b) to find the b which is the y intercept.

Use one of the points and input its x and y coordinates into the formula including the slope to solve for b.

-3= 2(0) +b

-3 = 0 + b

b = -3

f(x) is the same as y in the formula, meaning that the equation will be

f(x) = 2x -3
