There are an infinite number of possibilities, and not enough information
to decide which possibility is really the one inside the function machine.
Here are a few. Each of these gives the result that you described,
and there are an infinite number of others:
f(x) = x
f(x) = 2x + 1
f(x) = 10x + 9
f(x) = x² - 2
f(x) = 7x² - 8
f(x) = 31x³ + 30
f(x) = log( |x| ) - 1
f(x) = ln( |x| ) - 1
f(x) = x tan(45°)
.
.
etc.
The question is incomplete.
This is the complete question as I found in internet:
<span>Use substitution to determine which of the following points is a solution to the standard form equation below 5x-2y = 10
these are the points:
</span>
-1,5
1,5
0,-5
0,5
Answer: (0, -5)
Explanation:
point x y 5x - 2y = 10 ?
-1,5 -1 5 5(-1) - 2(5) = - 5 - 10 = - 15 ≠ 10 ⇒ not a solution
1,5 1 5 5(1) - 2(5) = 5 - 10 = 5 ≠ 10 ⇒ not a solution
0,-5 0 -5 0 -2(-5) = 10 ⇒ a solution
0,5 0 5 0 - 2(5) = - 10 ≠ 10 ⇒ not a solution
The answer is 35.
We have the ratio 7/9 cross multiply with x/45
7*45 = 315
315/9 = 35
Answer:
Step-by-step explanation:
Let p be the number of trees Wangari plants, and h be the time she spends planting them in hours.
We have been given that Wangari plants trees at a constant rate of 12 trees every 3 hours.
Let us find number of trees planted in 1 hour by dividing 12 by 3.
We can represent this information as:
Therefore, the equation relates the number of trees (p) Wangari plants, and the time (h) she spends planting them in hours.
8-3(p-4)= 2p
⇒ 8 -3p -3(-4)= 2p (distributive property)
⇒ 8 -3p+ 12= 2p
⇒ 8+12= 2p+3p
⇒ 20= 5p
⇒ 20/5= p
⇒ 4= p
Final answer: p=4~
