Given f(x)=10-2x find f(7)

Answers

Answer: -4

Step-by-step explanation: The equation is a simple function having two variables x and y. f(x) can also be written as y.

Therefore, another way to write a function is y = 10-2x.

The question requires you to insert the value of one variable and calculate the other. In this case you have to find the value of function when x=7.

Insert 7 in place of x. So, the equation will look as follows.

f(x) = 10 - 2*7

f(x) = 10 - 14

f(x) = -4

Therefore, when x=7 the value of our function f(x) is equal to -4.

f(7)=10-14=-4

The ratio of Sam age to Hanks is 5 to 3. If the sum of their ages is 24, how old is Hank?

Answers

How to solve this:

1. 5x + 3x = 24
2. x(5+3) = 24
3. x = 24/(5+3)
4. x = 24/(8)
5. x= 8
6. 5*3 = 15 (Sam) 3*3 = 9 (Hanks)

15 and 9 are the two ages so so hank is 9.

Can you tell me what is 15-2x=3x

Answers

15 - 2x = 3x
15 = 3x + 2x
15 = 5x
5x = 15
x = 15/5 = 3

The answer is 3x because first you will add 2x on both sides which will give you 5x on the other side. Then you divide 5x on both sides. 15/5x=3x
