Answer: 0.72
Step-by-step explanation:
Hope that helps :)
You can treat x and 2x+1 just as though they are real numbers.
So f(2x+1) = 3(2x+1) - 5 = 6x + 3 - 5 = 6x - 2
In the above, I made use of something called the distributive law which says that if a,b and c are real numbers, then a(b+c) = ab + ac.
Answer:
8 3/5
false
Step-by-step explanation:
All you need to do is plug in the points!
Here we go:
3(0)- 4(-5)-8
If it equals 12, then it is a point and an answer.
3(0)- 4(-5)-8= 12
(0,-5) is a point!
Next one:
3(4)-4(-2)-8
12+8-8
That equals twelve. (4,-2) is an answer as well!
I am going to quickly plug in the rest of the points, since I think you have the idea.
<span>(8,2) 3(8)-4(2)-8= 8 This is not an answer.
(-16,-17) 3(-16)-4(-17)-8 = 12 This is answer.
(-1,-8) 3 (-1)-4(-8)-8= 21 This is not an answer.
(-40,-34) 3(-40)-4(-34)-8= 8 This is not an answer.

I hope this helped you!
Brainliest answer is always appreciated!
<span>So we have a problem with two unknows and one equation. We have to express one over the other like this: 7a - 2b = 5a + b. First we separate one kind on the left side and the other kind on the right side: 7a - 5a = b + 2b. Then: 2a = 3b. Now we divide both sides by 2 and get: a= 3b/2.</span>
