Answer: -12/-5x
Step-by-step explanation: use slope formula which is y2-y1/x2-x1
-7-5/-2-3
-12/-5
And then add x after the slope because slopes have x after them
Repeated multiplication can be written as *exponentiation*. Here, 3.6 is multiplied by itself 4 times, so we would rewrite it as (3.6)^4 (in writing, you’d see it as 3.6 with a small 4 written to the upper right of the number)
15/5 + 40.7 -3^4
= 3 + 40.7 - 81
= -37.3
hope this helps! :)))
When a price is increased by x percent, we multiply the price by
.
In this case, the price is $1260 and it increases by 50%. When we put that in an equation:
So, the increased price is $1890.
After that, they applied a discount of 50% to the increased price. To find a decreased price we multiply the price by:
.
So, after the discount the final price becomes
.
