Answer:
x=2, y=13. (2, 13).
Step-by-step explanation:
y=4x+5
2x+y=17
----------
2x+4x+5=17
6x+5=17
6x=17-5
6x=12
x=12/6
x=2
y=4(2)+5
y=8+5=13
Answer:
81
Step-by-step explanation:
The term "of" can be translated to multiplication in problems like this.
So it's essentially saying multiply 45% to 180 and give me the result.
45% can be written as 45/100 in fractions (45 percent, where cent means 100 and per means division). 45/100 can be written as 0.45 in decimal form.
Now the problem reads 0.45 X 180. Using a calculator, we can solve this and the result comes out to be 81
Switch the variable x and y with each other. Then the correct option is B.
<h3>What is inverse of a function?</h3>
Let the function will be
f: X → Y
Then the inverse function will be
f⁻¹: Y → X
The function is given below.
f(x) = 3x – 10
Then the inverse function of the f(x) will be
Put y in place of f(x).
x = 3y – 10
3y = x + 10
y = (x + 10) / 3
Switch the variable x and y with each other.
Then the correct option is B.
