5 0
F(2)=(2)^2+(2)+4/-2

Simplify both sides of the equation.

f(2)=2^2+2+4−2

Simplify

2f=4

Divide both sides by 2.

2f/2 = 4/2

f=2

Answer:

f=2

For which values of a the system has at least one solution: x≤7 x≥a urgent pls help now
allochka39001 [22]

Answer:

We have the system:

x ≤ 7

x ≥ a

Now we want to find the possible values of a such that the system has, at least, one solution.

First, we should look at the value of a where the system has only one solution:

We can write the 2 sets as:

a ≤ x

x ≥ 7

So, writing both together:

a ≤ x ≤ 7

if a is larger than 7, we do not have solutions.

then a = 7 gives:

7 ≤ x ≤ 7

Here the only solution is 7.

Now, if a is smaller than 7, for example 5, we have:

5 ≤ x ≤ 7

Now x can take different values, so we have a lot of solutions.

Then the restrictions for a, such that the system has at least one solution, is:

a ≤ 7.

Mr. Adams earned $320 at his sales job yesterday. He received $200 in commissions and worked for 8 hours. What is his pay per ho
Paladinen [302]
The answer would be 15 because if you take the 320 and subtract the 200 dollars in commissions, then your left with 120. You then divide the 120 by 8, and you get $15 per hour
