Divide each side by 17 and you get x>1
Answer:
7 the answer is 7
Step-by-step explanation:
1. We assume, that the number 20 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 20 is 100%, so we can write it down as 20=100%.
4. We know, that x is 35% of the output value, so we can write it down as x=35%.
5. Now we have two simple equations:
1) 20=100%
2) x=35%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
20/x=100%/35%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 35% of 20
20/x=100/35
(20/x)*x=(100/35)*x -
20=2.85714285714*x -
20/2.85714285714=x
7=x
x=7
now we have:
35% of 20=7
we multiply both sides by x
then we divide both sides by 2.85714285714 to get x
Answer:
Step-by-step explanation:
To do these the main think to consider is the boundaries of the functions. In other words, check when the boundary is true and use that function. And so,
If we look at 1a.) f(-3) this means that x=-3. Now check the boundary condition of both equations first. For 6x-1 use it only if x<0 well is -3<0? Yes, so we will use this function. But let's check why we won't use 7x+3 this is because the boundary is x≥0 and since x=-3, -3≥0 is false so we dont use that function. Therefore:
f(x)=6x-1
f(-3)= 6(-3) - 1 = -18 - 1 = -19
1b.) Same idea so we will use 7x+3 because 0≥0 is true and so:
f(x)= 7x + 3
f(0) = 7(0) + 3 = 0 + 3 = 3
1c.) We will use the second equation since 4≥0 is true and so:
f(x) = 7x + 3
f(4) = 7(4) + 3 = 28 + 3 = 31
You will use the same logic to solve 2 and 3. Good luck! Hope this helps!
Rule: Negate x. (-x,y)
f(x)=g(-x)
f(x) 5x+8
g(x) = -5x+8
