Given f(x)=10-2x find f(7)
2 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 <em>y = 10-2x</em>.
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.

Answer:
134
Step-by-step explanation:
first, separate the floor into 3 different rectagles to calculate the area and then add them together.
area of rec=L*B
rec 1: 9.5*7=66.5
rec 2: (10.5-4.5)*(14.5-5-7)=15
rec 3:5*10.5=52.5
Then:
66.5+52.5+15=134
