Answer:
4 x + -43
Step-by-step explanation:
Simplify the following:
7 (x - 4) - 3 (x + 5)
Hint: | Distribute 7 over x - 4.
7 (x - 4) = 7 x - 28:
7 x - 28 - 3 (x + 5)
Hint: | Distribute -3 over x + 5.
-3 (x + 5) = -3 x - 15:
7 x + -3 x - 15 - 28
Hint: | Group like terms in 7 x - 3 x - 28 - 15.
Grouping like terms, 7 x - 3 x - 28 - 15 = (7 x - 3 x) + (-28 - 15):
(7 x - 3 x) + (-28 - 15)
Hint: | Combine like terms in 7 x - 3 x.
7 x - 3 x = 4 x:
4 x + (-28 - 15)
Hint: | Evaluate -28 - 15.
-28 - 15 = -43:
Answer: 4 x + -43
Answer:
it's the third one cause its square root so x can never be less then 0 but it can go in infinitely
Answer:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 13 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 13 is 100%, so we can write it down as 13=100%.
4. We know, that x is 100% of the output value, so we can write it down as x=100%.
5. Now we have two simple equations:
1) 13=100%
2) x=100%
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:
13/x=100%/100%
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 100% of 13
13/x=100/100
(13/x)*x=(100/100)*x - we multiply both sides of the equation by x
13=1*x - we divide both sides of the equation by (1) to get x
13/1=x
13=x
x=13
now we have:
100% of 13=13

Answer:
7.9 pounds of fruit
Step-by-step explanation:
In all means to add, so 7 + .9 = 7.9 pounds
Answer:
(4, 0)
Step-by-step explanation:
x=4 when y=0, and in x-intercepts, we are trying to find the value of x when y=0, which is why (4, 0) is the point of interception.
