Solve for x: 4x/5= -20
Answers
Answer:
x = -25
Step-by-step explanation:
Get x by itself by multiplying both sides by 5: 4x = -100
Get x by itself by dividing both sides by 4: x = -25

Answer:
2,200 meters.
Step-by-step explanation:
Given that an athlete takes 10 rounds of a rectangular path, 70 meters long and 40 meters wide, in order to find the total distance covered by him the following calculation must be performed:
((40 + 70) x 2) x 10 = X
(110 x 2) x 10 = X
220 x 10 = X
2,200 = X
Thus, the total distance covered by the athlete was 2,200 meters.

What issimplification?
In mathematics, reducing an expression, fraction, or problem to a simpler form is referred to as simplification. With calculations and solution, the problem is made simple. Make something simpler by simplifying it.
We are given a polynomial as
5x - 5 + + 4x -
+ 8
Now, in order to simplify the given polynomial, we will combine the like terms of the polynomial.
On combining the like terms, we get
+ 9x + 3
Hence, the polynomial after simplification is obtained as + 9x + 3.

Answer:
1.275
Explanation:
The given equation is:
f(x) = 0.01(2)ˣ
We want to find the rate of change from 2 to 10 which means that we need to find the slope from 2 to 10.
We start by getting the y-values for each of the given x-values:
at x = 2 ..........> y = 0.01(2)² = 0.04 ...........> point is (2, 0.04)
at x = 10 .........> y = 0.01(2)¹⁰ = 10.24 .........> point is (10, 10.24)
Now, we get the slope as follows:
slope =
Hope this helps :)
Answer: a. 1.275
Step-by-step explanation:
Let f(x) be any function.
Then the average rate of change from x= a to x= b is given by :-
The given function :
Then, the average rate of change from x = 2 to x = 10 will be :-
Hence, the average rate of change from x = 2 to x = 10 is 1.275.
